Fast EMI test receiver spans 10 Hz to 7 GHz

Staff - February 23, 2013

Intended for diagnostic and precompliance measurements in the frequency range of 10 Hz to 7 GHz, the Rohde & Schwarz ESRP test receiver measures conducted and radiated EMI, while a preselection option protects the front end against overloading and delivers reproducible measurement results.

The instrument offers two methods for measuring disturbance signals: the fast FFT-based time-domain scan and the conventional, but slower, stepped-frequency scan. Both methods comply with the CISPR 16-1-1 standard for EMC measurements.

In time-domain scan mode, the ESRP measures conducted disturbances in CISPR band B with quasi-peak weighting many orders of magnitude faster than conventional EMI test receivers using stepped-frequency scan. Time-domain scanning makes the ESRP useful for testing DUTs with function-specific short operating times in the automotive and lighting industries, such as starters and window lifters or fluorescent lamps in the warm-up phase.

In addition, the ESRP operates as a spectrum analyzer. A spectrogram function displays and records the analyzed spectrum versus time, and an IF analysis function displays the spectrum around disturbance signals.
