New EMC Diagnostic Option for Signal and Spectrum Analyzers

Rohde & Schwarz is adding an EMI measurement application option for the R&S FSVR real-time spectrum analyzer and the R&S FSV signal and spectrum analyzer. The new R&S FSV-K54 option enables developers to use the analyzers for EMC diagnostic and precompliance measurements. Users in the communications and automobile industry, in service and test labs and in universities alike will all benefit from the analyzers’ high measurement speed and sensitivity.

All electronic devices must be tested for electromagnetic compatibility (EMC) before market approval can be granted by regulatory bodies. It pays to measure electromagnetic interference (EMI) early in the product development cycle so that effective countermeasures can be developed in the lab well before CE certification. This prevents expensive product redevelopment and ensures a timely market launch. Equipping the R&S FSVR real-time spectrum analyzer and the R&S FSV signal and spectrum analyzer with the R&S FSV-K54 option makes it possible to assess a DUT’s EMC properties in the prototype phase.

This new solution allows users to analyze specific EMI characteristics that were previously detected in an EMC lab. Developers can determine the effectiveness of shielding measures and the effects of changes in the circuit or design. The optional spectrogram mode, which displays the amplitude and frequency of the signal versus time, is a particularly valuable aid during development. The R&S FSVR real-time spectrum analyzer reliably detects even sporadic, intermittent interferers and narrowband interferers that drift in frequency. It seamlessly analyzes a frequency spectrum of up to 40 MHz in a frequency range up to 40 GHz .

The R&S FSV-K54 option contains standard-compliant EMI detectors such as quasi-peak, CISPR-average and RMS-average and supports EMC bandwidths for both commercial and military standards. It also offers limit line and transducer options for typical measurement tasks as well as a logarithmic frequency axis for displaying the measured spectrum. The ability to link the analyzer’s markers to the various EMI detectors helps users quickly find critical areas. Remote-controlled measurements are possible with the R&S EMC32 and R&S ES-SCAN PC software packages, which can also be used to generate test reports and document measurement results.

The R&S FSVR real-time spectrum analyzer and the R&S FSV signal and spectrum analyzer are available in various models up to a maximum frequency of 40 GHz. In addition to the R&S FSV-K54 EMI measurement application, they offer numerous options for measuring RF parameters and analyzing digitally modulated signals such as LTE, WCDMA, CDMA2000®, TD-SCDMA, GSM, WiMAXTM, WLAN and Bluetooth®.

The R&S FSV-K54 EMI measurement option for the R&S FSV and R&S FSVR is now available from Rohde & Schwarz.
