Engineered for reliable pre-compliance and powerful diagnostics 
The R&S®ESRP EMI test receiver has been designed for diagnostic measurements during development and for pre-compliance measurements to prepare products for final certification testing. It measures electromagnetic disturbances in the 10 Hz to 7 GHz frequency range, using either conventional stepped frequency scans or FFT-based time domain scans to significantly speed up measurements. The R&S®ESRP is also a full-featured, powerful signal and spectrum analyzer for lab applications. The touch screen and straightforward menu structure make the R&S®ESRP easy to operate in any mode.

Precompliance measurements
The R&S®ESR has been designed with the main focus on diagnostic measurements in line with commercial EMC standards and on all measurements in the runup to final product certification. Equipped with optional preselection (R&S®ESRP-B2), including a 20 dB preamplifier, the R&S®ESRP performs measurements of intermittent disturbance signals with pulse repetition rates of 10 Hz or higher in line with the CISPR 16-1-1 basic standard.
 
The R&S®ESRP has a standard frequency range from 9 kHz to 3.6 GHz or 7 GHz. The R&S®ESRP-B29 option extends the frequency range down to 10 Hz.
 
The R&S®ESRP weighting detectors, including CISPR-average (average detector with meter time constant) and RMS-average, meet the requirements of the CISPR 16-1-1 basic standard, as do the EMI resolution bandwidths (200 Hz, 9 kHz, 120 kHz as 6 dB bandwidths, 1 MHz as impulse bandwidth). 6 dB resolution bandwidths in decade steps from 10 Hz to 1 MHz are optionally available (R&S®ESRP-B29), for example, to enable measurements in line with MIL-STD-461, DO-160 and ICNIRP guidelines on exposure limits.
 
EMI measurements in spectrum analyzer mode
Like all Rohde & Schwarz EMI test receivers, the R&S®ESRP is based on a powerful signal/spectrum analyzer platform. EMI analysis during development is possible in the spectrum analyzer mode, with or without preselection (option) activated.
 
Up to 16 configurable markers are placed on the frequency of disturbance signals to conduct a targeted analysis. Markers can be coupled with a CISPR weighting detector to enable direct comparison with limit values. The spectrum can also be displayed along a logarithmic frequency axis, which simplifies result analysis across a wide frequency range and displays limit lines in compliance with relevant standards. Critical frequencies are presented in a peak list, enabling fast comparison of disturbance signals with limit lines.
