Wireless Multi Instrument Synchronization Module WCMI-8

Features

Easy expanding the number of input channels

Using WCMIs, multiple oscilloscopes are combined to a scope with many input channels. It’s then easy to create and control a scope with e.g. 16 input channels. 128 input channels is possible as well.

Wireless connection

An accurate wireless RF connection between the WCMI modules shares the trigger signals to start the combined scopes at exactly the same moment. The WCMI module has an automatic time synchronization system that takes care that all sample clocks of the oscilloscopes are synchronized.

Multiple measurement points at large distance

Many signals can be measured synchronously, using scopes that can be up to 400 m apart from each other. No long cabling is required between the scopes and the computer, which makes the setup very easy and hassle free.

Software

The Multi Channel oscilloscope software automatically detects how many instruments are equipped with a WCMI module. All detected oscilloscopes, connected via WiFi, LAN or USB, are combined to one single oscilloscope with a total number of channels that equals the sum of the number of channels of the detected oscilloscopes.

New functions that make the best scopes better

WCMI is a Plug and Play module
Wireless combining of multiple measurement instruments
Software automatically searches for available WCMI modules
Automatic sample clock synchronization of of each measurement instrument
Triggering possible on all combined instruments
Fully galvanic isolation possible when measuring with multiple instruments
Measure distant measuring points synchronized as with one instrument
Modules suitable for the 868 MHz band (WCMI – 8) and 915 MHz band (WCMI – 9)

The Wireless Multi Instrument Synchronization Module WCMI is a module that allows to combine and synchronize two or more WiFiScopes or Handyscopes via an RF wireless trigger connection. The scopes can be up to 400 m apart from each other.

The WCMI is compatible with the WiFiScope WS6 DIFF, the WiFiScope WS6, the WiFiScope WS5, the Handyscope HS6 and the Handyscope HS5.

The WCMI is available in two models:

WCMI – 8, for the 868 MHz band, region Europe
WCMI – 9, for the 915 MHz band, region America (North, Central and South)
These are available as single module and as set of two modules. To combine and synchronize oscilloscopes, a minimum of 2 WCMI modules is required. For each scope in the combined instrument, a WCMI modules is required.
