Rohde & Schwarz ESR EMI test receiver

Monday, 20 August, 2012 | Supplied by: Rohde & Schwarz (Australia) Pty Ltd

The R&S ESR EMI test receiver is available in two different models for frequencies ranging from 10 Hz to 3 or 7 GHz to meet the requirements of users who perform EMC certification on commercial equipment. It covers all commercial standards relevant for test houses and EMC labs used by electrical equipment manufacturers and their suppliers.

The receiver has diagnostic tools such as spectrogram display, real-time spectrum analysis and IF analysis to help developers detect and eliminate EMI. It features time domain scan, an FFT-based receiver technology said to allow it to perform measurements up to 6000 times faster than other EMI test receivers. This measurement method is suitable when the DUT can only be operated for short periods for testing, eg, in the automotive and lighting industry.

The spectrogram function displays the analysed spectrum over time and records measurements for up to five hours, allowing developers to detect sporadic interferers.

The frequency mask trigger responds to specific events in a spectrum. If the mask is violated, a trigger is activated. The measurement is stopped, and the user can analyse the exact cause and effect of the interferer.

The persistence mode allows users to clearly differentiate between pulse interferers and continuous interference. It displays the probability distribution of occurring frequencies and amplitudes in various colours, making it possible to detect interferers that are hidden by broadband signals.

The receiver also provides a conventional stepped frequency scan so the user can compare it with existing results. The software can be used to remotely control the receiver and integrate it into EMC systems for automated measurement sequences.
