EMI Pre Compliance Tester Handyscope HS6-DIFF-1000XMESG-W5

The powerful capabilities of the Handyscope HS6 DIFF – 1000XMESG EMI analyzer give the user the possibility to quickly perform a good EMI compliance test. With this cost effective test, time and money are saved by avoiding extra visits to expensive EMC testing facilities. The supplied EMI probe set TP-EMI-HS6 contains three magnetic field (H field) probes and one electric field (E field) probe. The tripod ensures that the probes can be positioned properly at the object under test.

The Handyscope HS6 DIFF – 1000XMESG EMI analyzer has a very low resolution bandwidth of up to 7.45 Hz (at a span of 500 MHz), which is unique in its class. As a result, details in each part of the spectrum can be analyzed thoroughly.

Note: A resolution bandwidth of 7.45 Hz at a span of 500 MHz gives a total of 67,108,864 spectral components. When your display is 1920 pixels wide, you require 34,952 displays to show the full spectrum 1:1. 34,952 displays with a width of 50 cm (23 inch diagonal) each, gives a total display width of 17.47 km (10.85 mile)! Therefore, if you zoom in 35,000 times, you will get the spectral components 1:1 on your display. That is exceptional for an EMI analyzer and it makes each frequency component very well visible.

The large dynamic range of 140 dB allows the measurement of a wide variety of interference frequencies. Standard limit lines according to EN61326-1:2006/EN55011:2007 can be switched on or off. The resolution bandwidth and frequency range can be selected individually.

There are three operating modes: Normal, Average and Max Hold. Normal mode displays the spectrum of the source trace. Averaging mode is effective in reducing the noise of the signal, to see more of the harmonic or carrier detail. You can select the number of spectra to be averaged. Max Hold displays the maximum level that the signal reaches and is useful for frequency measurements where it shows the history of peak values across the frequency axis. Averaging and Max Hold history can be cleared manually to start a new measurement.

With the extensive marker capabilities in the graph, various aspects of the spectrum can be measured.

The amplitude unit can be set to dB, dBv, dBmV, dBµV, dBµV (at 10m) and dBm. The amplitude range can be set to one of three ranges: 0 to 100 dBµV, 20 to 120 dBµV or 40 to 140 dBµV. For accurate amplitude measurement, a flat top window is used by default. Besides the flat top window, eight other windows can be selected from.

The EMI analyzer can also be used as normal spectrum analyzer. With a biconical antenna or Combilog Antenna a spectrum of 10 MHz to 500 MHz can be measured.

Figure 4 shows a spectrum measured with a Combilog antenna which was placed outside. Next to the full spectrum from 0 Hz to 500 MHz, there is also a view with the FM band of 87.5 MHz to 108 MHz, an FM radio station at 92.2 MHz and even an AM radio station at 1600 kHz. The time domain signal is also shown, as well as a zoomed in part of the time domain signal. All windows are real time and correlations between different frequencies and the time domain signal can be conveniently viewed. The multi window feature of the EMI analyzer offers the user unlimited analysis and display capabilities.

The TiePie HS6-DIFF-1000XMESG-W5 is a high-performance USB oscilloscope engineered specifically for EMI pre-compliance analysis. Featuring four fully differential inputs, up to 1 GSa/s sampling rate, 250 MHz bandwidth, and a dynamic range of 140 dB, it enables precise diagnostics of radiated and conducted emissions.

Its integrated EMI spectrum analyzer includes multi-window FFT views, allowing users to examine the full spectrum (up to 500 MHz) while simultaneously zooming in on multiple frequency bands. This unique capability offers a significant advantage over traditional spectrum analyzers, which typically display only one view at a time.

The analyzer features a resolution bandwidth of just 7.45 Hz, providing over 67 million spectral components across the 500 MHz span. This allows users to detect even the smallest frequency emissions. With compliance limit lines for EN55011 and EN61326, it supports fast, standard-aligned diagnostics.

Included is the TP-EMI-HS6 probe set, featuring three magnetic field (H-field) probes and one electric field (E-field) probe. A tripod and SMA/BNC cables ensure precise probe positioning and reliable connections. Modes such as Normal, Average, and Max Hold offer additional flexibility in visualizing signal behavior over time.

Powered via USB and enhanced by SafeGround technology, the HS6-DIFF-1000XMESG-W5 is safe, portable, and ideal for lab or field EMI investigations—delivering comprehensive insight into signal sources and EMI behavior in real time.
