Meinberg News

Meinberg manufacturer of the most powerful time and frequency synchronization solutions, is proud to announce the availability of Meinberg´s new network time sync module generation, which provides a future-proof platform for your IEEE 1588 / SyncE / Carrier Grade NTP infrastructure.
The HPS-100 offers the ability to support up to 2048 PTP-Clients in Unicast Mode (at 128 Sync and Delay Requests per second), as well as more than 250.000 Delay Requests per second in Multicast or Hybrid mode due to a powerful FPGA-based Packet Generator engine. The card is equipped with a 1GE interface as an RJ45/SFP combo port and 2 SMA outputs for configurable pulse outputs like 1-PPS, 10 MHz and 2.048 MHz.The HPS-100 can be configured to run in Master or Slave mode. It supports all major PTP profiles: Default, Power, Telecom (Frequency and Phase profiles), SMPTE, AES67/RAVENNA or IEEE 802.1AS profile. This makes it the most flexible and interoperable PTP solution on the market, suitable for a wide range of applications.

The module additionally also offers an NTP Server mode with 10 ns accurate time stamps due to a hardware time stamping NTP engine.

For providing a cost effective solution, a flexible license model is available to select the Client capacity power that is needed for a certain application.

A lot of IEEE 1588 slave devices or NTP clients from different market segments can be synchronized, for example eNodeBs for LTE base stations, Linux servers with hardware-assisted time stamping support for high-frequency trading applications, IEEE 1588 compatible IEDs in Smart Grid environments or IP-interconnected Audio / Video devices in broadcast studios. The Synchronous Ethernet function provides a highly stable frequency transport over Ethernet networks. The card supports to either use an incoming SyncE signal from the network as a source or generate SyncE as a Master.

The HPS-100 module is compatible with Meinberg´s Intelligent Modular Synchronization (IMS) platform, which is famous for it´s high level of scalability, flexibility, versatility and reliability. The modular design of Meinberg´s IMS systems allows features like field-replacement and hot-swap capabilities for I/O and power supply modules. This concept ensures future-proofness and expandability by allowing to add or replace modules when new technologies or interfaces are required.

Pickering News

A programmable resistor is designed to emulate the use of resistive sensors and variable resistors in systems when testing devices such as engine controllers.
In their simplest form, Pickering´s programmable resistors consist of a basic chain of resistance values switched in or out of circuit with reed relays, electro-mechanical relays or solid state switches. We also offer multi-channel programmable resistors with very fine value adjustment and high accuracy including programmable resistive bridges for strain gauge simulation.

Applications for Programmable Resistors

Programmable resistors have many applications in automated test, verification and simulation systems:
Strain Gauge Simulation:

Used in mechanical systems to measure the tension or compression of structural components. Simulation requires extremely fine setting resolution with high accuracy and temperature stability.
Temperature Sensor Simulation:

Simulation of resistance based temperature sensors such as positive or negative temperature coefficient thermistors.
Resistance Temperature Detectors (RTDs) can be wire-wound or thin film. Both PT100 and PT1000 types can be simulated, requiring fine setting resolution.

Pressure Sensor Simulation:

For the simulation of pressure senders in mechanical systems or barometric pressure sensors in applications such as altimeters in the aerospace industry.
Select on Test Resistance:

A programmable resistor can be used in a test environment where a component´s value is optimized at the production test stage.
Load Resistor:

Where a circuit under test requires the connection of an external load.
Position Sensor Simulation:

Rotary or linear position sensors in mechanical systems usually take the form of potentiometers and are used in applications such as throttle position senders in automotive systems.
Switch Simulation:

Can be used to simulate the contacts of a worn or contaminated switch for automotive ECU (Engine Control Unit) testing.
Fault Insertion:

Can be used for injecting fault conditions when testing the fault tolerance of aircraft or automotive control systems.

Selecting a Programmable Resistor

Pickering offers a variety of PXI programmable resistor modules and PCI programmable resistor cards for use in medical, automotive and aerospace applications. We offer different features for use in different applications, these include:

Platform:
Solutions in both the PXI and PCI formats
Ethernet control of any of our PXI modules when installed in our LXI Chassis

Number of Channels:

Between 1 and 18 channels
Range:

Many resistance ranges are available with values from a short circuit to millions of Ohms
Modules and cards are available with a narrow setting range and very fine resolution for simulating sensors and strain gauges

Resolution:

Resistance setting resolutions are available from 10Ω to 2mΩ for a wide range of applications
Power Handling:

Generally 100mW for precision programmable resistors and up to 1W for standard programmable resistors
We also offer a PXI programmable load module with up to 15W power handling (model 40-292)

Minimum Resistance Value:

The lower the minimum resistance value required the greater the errors caused by relay contact resistance and copper trace losses.
Generally, modules and cards with a low minimum resistance do not have as wide a range of resistance values as those with higher minimum resistances.

Accuracy:

High accuracy requires careful design to ensure low loss paths, management of thermoelectric EMF and the use of higher stability resistors
Calibration Port:

A calibration port allows the user to check the resistor channel without having to disconnect the front panel connector. It can be used to connect any of the resistor channels to a DMM to perform an accurate four terminal measurement.

Custom Programmable Resistors:

If the desired accuracy, precision, range, number of channel, power handling, etc is not available, we are often able to configure custom builds or even design a new version of a PXI/PCI model.
Our entire range use real resistors, they do not use current loads or other electronic means to control the resistance value. Therefore they behave in exactly the same way as an actual resistor.

We carry over 130 PXI modules and over 120 PCI cards featuring:
Up to 18 channels in a single PXI/PCI slot

Resistance ranges from 1Ω to 22MΩ

Resolutions down to 2mΩ with accuracies down to 0.03%

PXI modules can be supported in our LXI Chassis

Supported by a full range of connector and cabling solutions

Meinberg News

Meinberg manufacturer of the world´s most powerful solutions for time and frequency synchronization, will show its latest synchronization systems and monitoring/audit solutions for the financial sector at several industry relevant events.
The Spring 2016 STAC Summits organized by the Securities Technology Analysis Center (STAC) bring together industry leaders to focus on challenging areas of financial technology. STAC provides technology research and testing tools based on community-source standards. This accelerates technology selection at user firms while reducing the sales cycle for vendors. The standards are developed by the STAC Benchmark Council ®, a group of major financial firms and other “algorithmic enterprises” as well as leading technology vendors. Through a variety of online and in-person forums, the Council discusses key technology challenges and new solutions for them.

With MiFID II set for January 3, 2018 the financial industry is currently trying to meet the clock synchronization UTC divergence. MiFID II will introduce the requirement for trading venues, their members and participants to synchronize the business clocks used to record the date and time of reportable events to UTC with an accuracy of 100 microseconds. How to best achieve this accuracy, monitor and demonstrate compliance, with a robust and competitive implementation is a major challenge facing the global financial sector.The objective of the MiFID II Workshop presented by EIE, ITSF and NPL is to help financial institutions, equipment/service providers and implementers to better understand the motivations and requirement of time-stamping required by MiFID II, and manage the delivery. This workshop will bring together interested parties from the regulatory, finance and measurement communities.

As a new member of the STAC Council, Meinberg will be attending the STAC events in London and Chicago in May. Meinberg will be proving an innovation round-up presentation with the title “Measuring MiFID II Compliance: How to Audit and Monitor your Time Synchronization Infrastructure” and operates an exhibition stand showing a selection of Meinberg´s latest synchronization solutions for financial applications.

The LANTIME M1000, equipped with the new generation of the Meinberg time stamping unit HPS (High Precision Synchronization) provides a future-proof platform for your IEEE 1588 / NTP infrastructure. The high-performance processing unit, the 1-step master clock and the 1GE interface with SFP slot support a very large number of PTP clients. Thousands of IEEE 1588 slave devices or NTP clients can be synchronized, both in IPv4 and IPv6 networks, for example transaction servers running high-frequency trading applications. For NTP-based synchronization, each of the HPS-100 network interfaces of the LANTIME M1000 can be configured to act as a carrier grade NTP server with 10 ns time stamp accuracy, serving up to 12,000 NTP requests per second on each port. Each HPS module can serve time to up to 2,048 PTP Slaves at full Unicast rate (128 sync/128 delay req. per second) or 250K DelayRequests per second in Enterprise Profile/Hybrid mode. Each M1000 can hold up to four HPS modules, enabling a performance increase to 90,000 NTP requests/second or 8,096 unicast PTP Slaves (at full rate). As a part of the IMS family, the M1000 allows users to add or replace modules without having to shut down the system. The M1000-S is the compact version of the M1000 and provides the same outstanding synchronization capabilities.

As part of the Intelligent Modular Synchronization System (IMS) family, the M1000 and M1000S both allow field-replacement and hot-swap capabilities for IO modules and power supplies. This concept ensures future-proofness and expandability by allowing to add or replace modules when new technologies or interfaces are required and makes this product one of the most scalable and flexible synchronization solutions on the market.

Meinberg News

Meinberg Sync Academy in cooperation with Sincron Sistemi SrL, our local partner, organized Synchronization Seminars in Rome (April 11th) and Milano (April 13th).
The two seminars have been a great success, with more than 100 participants from the most important companies in the field of Broadcast, Defense, Energy, Finance, IT, Telecom and Transport.After a brief overview of various Synchronization methods like GPS, Glonass, Beidou, DCF77, IRIG, NTP, PTP IEEE1588, PPS, 10 MHz the new family IMS (Intelligent Modular Synchronization) of Meinberg was highlighted and it was demonstrated how specific solutions for different synchronization applications could be configured. LANTIME M500 IMS and M3000 models were used to showcase the flexibility and adaptibility of the Meinberg IMS system. The NTP mechanisms, related performances in various operating systems and explanations for all relevant setting options have been presented. In a live demo part, practical examples for the discussed topics were shown.

Special attention was paid regarding PTP IEEE1588, we revisited its historical evolution, explained different modes of operation, switch and router roles and discussed performance, pros and cons of Unicast and Multicast communication and the various profiles used in Power and Telecom applications.

A special section of the seminar was reserved to creating different IMS configurations by using the large selection of modules available from Meinberg. Redundancy concepts of synchronization, its various possible implementations and a couple of case studies stressing advantages of down converted antenna were shown. The conformance with ITU-T G.811 and the outstanding performance of the low jitter PPS output were mentioned, too.

In the following session, the Network Management using the Espy II Software from Bridgeworx was discussed in details. In a live simulation, the management and monitoring capabilities of Meinberg M3000 IMS using Espy II and some failure simulations were demonstrated. Many operators currently have existing deployments (or devices from multiple vendors) so the Espy ability to not only manage Meinberg IMS devices is a big advantage, avoiding to have separate management systems for each vendor.

Finally live demos using different PTP profiles (IEEE 1588v2 Default Profile and ITU-T G.8265.1 Frequency Profile) for PTP synchronization between Lantime M500 acting as slave and M3000 used as PTP Grandmaster were shown. At the end the attendees expressed great appreciation of the Sync Seminars and the Meinberg and Sincron team received a lot of positive feedback.

GW Instek News

GW Instek launches new PEL-3000E series programmable single-channel electronic load. In the series, PEL-3031E provides 300W (1V~150V/60A) current sink capability. Inherited from the PEL-3000 series, PEL-3031E has an easy-to-read LCD panel and user-friendly interface. This model features high speed and accurate measurement capability for electronic component, battery, portable charger and power products that require low to medium power consumption. The PEL-3000E series is designed for current sink operation starting from 60mA and aims at measurement applications, including charger, adapter, various power supply equipment, and portable charger. The PEL-3000E has seven operating modes. Among them, four basic operating modes are constant current, constant voltage, constant resistance, and constant power. Three other combined operating modes are constant current + constant voltage, constant resistance + constant voltage, constant power + constant voltage. Users can select operating modes based upon products’ test requirements. For C.C. mode, electronic load will sink a constant current according to the set current value; for C.V. mode, electronic load will attempt to sink sufficient current to control the source voltage to the programmed value; for C.R. mode, electronic load will sink a current linearly proportional to input voltage according to the set resistance value; for C.P. mode, electronic load will initiate load power sinking operation (load voltage x load current) in accordance with the programmed power setting.
To meet the requirements of different test conditions, the Static function is to sink a constant current; the Dynamic function is to periodically switch between two sink conditions, and the Sequence function is to provide tests for more than two sink conditions. The sequence function can be divided into Normal Sequence and Fast Sequence. Normal Sequence are the most flexible means of generating complex sequences that can facilitate users to establish a set of changing current sink conditions based upon different sinking conditions (CC, CR, CV or CP mode) and time(adjustable range: 1ms to 999h 59min 59s). Fast sequence allows time resolution of 25us to be set for the smallest step. Setting parameters for multiple steps can simulate consecutive current changes of various real load conditions. For instance, while using an electronic load to test a power-driven tool’s power supply we can first obtain waveforms by an oscilloscope and a current probe from the tool, and subsequently, use the obtained waveforms to edit simulated current waveforms, via electronic load’s sequence function, to test the power-driven tool and to analyze its operational status. The Soft Start function allows users to determine the rise time of current sink that is to decide the required time to reach electronic load’s set current, resistance or power value. Setting a proper rise time for Soft Start is effective to counter output voltage fluctuation caused by DUT’s (power supply) transient output current. It is worth noting, General DC loads do not have the soft start function. When conducting high speed current sink operation, the inductance effect on the cable connecting electronic load and DUT will lead to transient voltage drop on electronic load’s input terminal, therefore, that will result in Voltage Non-monotonic increase. PEL-3000E’s soft start function not only allows output voltage to be Monotonic increase, but also prevents inrush current and surge voltage from happening on DUT. For instance, tests using a power supply, LED and a DC load (activate the soft start function) can prevent inrush current and surge voltage from causing damages on LED.

The PEL-3000E is equipped with the count time function to obtain total time for electronic load’s current sink that helps users estimate DUT’s power capacity. The cut off time function is for users to control the total time of electronic load’s current sink. Both flexible time control functions increase the test adaptability of electronic load. UVP can be applied on battery discharge tests. Electronic load will cease operation if battery’s voltage is lower than the set UVP threshold to protect battery from over discharge. Other than that, PEL-3000E provides users with analog control terminal to control PEL-3000E from external voltage, external resistance and switch. Analog control terminal can also monitor electronic load’s status and display protective alarms.

GW Instek News

GW Instek rolls out the new AFG-3000 series arbitrary function generators, including 20MHz/30MHz single channel and dual channel models, designed to meet industry, scientific research, and education applications. In the design of isolated output, all output channels are earth ground isolation, which is suitable for test applications of floating circuit. For instance, connecting an AFG-3000 with a power supply’s DC voltage, the maximum AC-DC cascaded output reaches +42V or -42V. Each channel of dual channel models can be operated independently or multi units can simultaneously function without taking grounding reference into consideration. Applications are, for instance, the ignition control or transmission device of automotive electronics. The series features sample rate of 250MSa/s, 16-bit resolution, and 8M point memory depth for arbitrary waveform generation. Users not only can save the edited waveforms to the memory to build arbitrary waveforms, but also rebuild waveforms by the AFG-3000’s built-in DSOLink function with a GW Instek digital storage oscilloscope.
The AFG-3000 series supports synchronized phase for multi channel operation up to 6 units and 12 channels. A reference input connector is available allowing an external 10 MHz time base to synchronize the internal clock and elevate the frequency output accuracy. The series supports frequency sweep and amplitude sweep that can also integrate other functions, including linear/logarithm, one-way (saw tooth)/two-way (triangle), continuous/single trigger/gated trigger to meet various application requirements by applying different sweep methods. Frequency sweep tests the frequency response of electronic components such as filter and low frequency amplifier. Amplitude sweep simulates vibration tests (requires a vibration tester), and it also conducts aging tests of various materials and linearity tests of low frequency amplifier. The main features of the AFG-3000 series include output amplitude from 1mVpp to 10Vpp (connected with a 50 ohm load); frequency range from 1uHz to 20MHz or 30MHz; 1uHz frequency resolution; and built-in sine, square, pulse, triangle, ramp, DC voltage, harmonic and noise. The waveform width, rise edge time and fall edge time of pulse waveform can be adjusted flexibly. Pulse waveform, with duty cycle from 0.017% to 99.983%, can be applied as trigger signals. Users can conduct arbitrary editing via 65 built-in function waveforms. The series supports AM/FM/PM/FSK/PWM modulation, frequency sweep, amplitude sweep and burst to satisfy industrial application requirements. Dual channel models provide SUM modulation, coupling, tracking, and phase to meet the test requirements of differential signal, phase control and amplifier distortion. Built-in 8th harmonic signal generator simulates harmonic signal of switching power supplies and it also tests EMI power filter characteristics. The AFG-3000 series provides free arbitrary waveform editing software (AWES) for users to quickly edit waveforms from the built-in diagrams so as to execute measurements.

Meinberg News

Meinberg manufacturer of the world´s most powerful time and frequency synchronization equipment, is proud to announce the outstanding EANTC Interoperability Test results of the tested Meinberg devices and a successful exhibition presence at one of the major global MPLS+SDN+NFV events.
In January and February 2016, interoperability of Meinberg´s telecom optimized synchronization systems had been successfully tested at the EANTC Interop Test Event in Berlin, Germany. The clock synchronization part of this year´s EANTC Interop Tests included topics such as delay asymmetry, multi-vendor grandmaster changeover, holdover performance and microwave transport, which are some of the fundamental areas of interest for service providers. Interoperability tests of the participating devices covered the two published ITU telecom profiles for frequency and phase/time, including full on-path support and assisted partial timing support (APTS) network environments.

Two of this year´s tests were affected by a rather unusual event, a GPS Ground System anomaly, which later has been confirmed by an official US Air Force press release. This type of anomaly expanded the category GPS jamming and GPS spoofing and perfectly fitted in this year´s clock synchronization testing program regarding performance in optimal and suboptimal conditions (e.g. source failover between two different grandmasters).

Meinberg successfully participated in 15 test scenarios, proving interoperability of the LANTIME M1000-S and LANTIME M4000 model with devices from Ericsson, Huawei, Omnitron, ADVA and Microsemi. The unmatched flexibility of the LANTIME IMS platform allowed to use the M1000S and M4000 in various roles during the tests.

Details and descriptions of each test and their results are summed up in the EANTC Whitepaper, which can be downloaded at:

EANTC Interop Whitepaper

The different EANTC Interop test scenarios were demonstrated and explained at the Public Multi-Vendor Interoperability Showcase during the 2016 MPLS+SDN+NFV World Congress in Paris, France. A joint presentation of Ericsson and Meinberg during this event explained one of the synchronization tests concerning sync over a Microwave link. Meinberg also hosted a special event for their customers in Paris in cooperation with the local Meinberg partner for France, JTELEC.

Meinberg News

The Public NTP Services Project (www.ntp.org) announced on Dec 19th that the current versions of the reference implementation of NTP contain a number of security related bugs that affect all NTP 4.x versions.

CVE-ID:

CVE-2014-9293CVE-2014-9294CVE-2014-9295CVE-2014-9296

*1. Description of the Problem*
The version of the reference implementation of NTP installed on LANTIME firmware appliances and included in our Windows NTP Installer contains several bugs that can cause security vulnerabilities.

Most of the recently reported issues are only affecting systems which have the so-called Autokey feature enabled. Due to the fact that Autokey has been found to have structural security flaws and therefore is not considered a secure way of providing NTP services, Meinberg recommends to not enabling this feature if possible.

Another set of the reported vulnerabilities are only exploitable if mode 6/mode 7 packets are not restricted on the target system to avoid that untrusted IP addresses are able to send these packets.

*2. Affected Systems*
All LANTIME Firmware Versions before V6.16.006 are affected by this vulnerability.
All NTP V4.x Versions before 4.2.8 are affected according to the information we received from the maintainers of NTP. We are still investigating whether this affects LANTIME V3.x, V4.x and V5.x firmware versions (using NTP 4.2.0b) and will update this page if we find out that they are not affected. Until then we consider these firmware generations to be affected.

*3. Possible Defense Strategies*

Meinberg Products
We recommend to set up firewall protection for all LANTIME V3.x systems still in use and reachable from untrusted networks. For Meinberg LANTIME products running firmware versions V4.x and V5.x, the recommended configuration changes outlined below can be applied using the “Edit additional NTP configuration” function on the NTP configuration page of the web UI.

In order to protect LANTIME systems that cannot be updated to V6.16.006, we recommend to disable Autokey using the Web UI of your LANTIME systems. Please note that this feature is disabled by default and therefore only needs to be disabled again if it had been actively enabled.

In order to restrict the use of Mode 6/Mode 7 packets on your LANTIME systems, please add the following lines to the “additional NTP configuration” of your LANTIME:# LANTIME Additional NTP Configuration:restrict default limited kod nomodify notrap nopeer noqueryrestrict -6 default limited kod nomodify notrap nopeer noqueryrestrict 127.0.0.1

IMPORTANT: the last “restrict” line is required to ensure that the internal status updates continue to work. Failing to add this line (restrict 127.0.0.1) can cause problems with displaying the NTP status on the Web UI and on the front display etc.

LANTIME products running V6 firmware versions can be protected either by using the same approach as V4/V5 or by disabling mode 6/mode 7 support generally using the “Disable mode 6 / mode 7” option in the “General Options” section on the NTP page of the web interface.

Other NTP Installations
If updating your NTP installation to 4.2.8 or a patched version provided by your OS vendor is not possible, you can disable the support for handling NTP mode 7 requests by using the “restrict” statement. The “noquery” flag will disable mode 7 support (including the “monlist” feature) and can be set up in a “default restrict” statement to be applied to all incoming requests. NTP allows to define default “restrict” setting and different restrictions for specific IPs and/or subnets. You should also disable Autokey if it is enabled in your configuration by removing, or commenting out, all configuration directives beginning with the crypto keyword in your ntp.conf file.

NTP packets are used for requesting status information from the NTP daemon and allow attackers to obtain knowledge about the NTP version and the OS version running on your NTP server as well as other information like upstream NTP servers and details about the current status of your NTP synchronization. In addition to disabling status query support, Meinberg recommends you disable configuration change support as well, which can be achieved by using the “nomodify” flag.

NOTE: To find out more about the meaning of the configuration statements used in this article, please refer to http://doc.ntp.org for further explanation. The configuration examples provided here should work with all ntpd versions from 4.2.0 to 4.2.6 with the obvious limitation that the IPv6 related configuration lines only work with versions that support IPv6.

Add the following lines to your NTP configuration file (ntp.conf):

# for IPv4 restrict default limited kod nomodify notrap nopeer noquery# for IPv6restrict -6 default limited kod nomodify notrap nopeer noquery

This will for all incoming requests disable mode 6 and mode 7 support and in addition enables the “kiss-o´-death” (kod) functionality of NTP. It will still allow everybody to send a regular NTP request (for time), but prevents all IP addresses not specifically configured from using mode 6 (status) or mode 7 (control) requests to obtain detailed information about your NTP server or use the mode 7 “monlist” feature for traffic amplification attacks.

It often makes sense to allow full access from the server itself, you can remove the restrictions for the local host by using these “restrict” lines:

# for IPv4 restrict 127.0.0.1# for IPv6restrict -6 ::1

In order to disable these restrictions for specific hosts or whole subnets that need access to the “monlist” and other status information provided by ntpd with the mode 6/mode 7 approach, additional “restrict” statements can be added for each of those IP addresses or subnets. If you want to allow an administrator PC to access the detailed NTP status information, you can add another “restrict” statement:

# for IPv4 restrict 192.168.0.20 nomodify nopeer

Or, to define different restrictions for a whole subnet:# for IPv4 restrict 192.168.0.0 mask 255.255.255.0 nomodify kod

You can define multiple “restrict” lines to grant access to multiple hosts and subnets. More about possible access control configuraton functions can be found on the NTP documentation site of the NTP Project (doc.ntp.org).
