The Rohde & Schwarz ESRP7 is an EMI test receiver and signal/spectrum analyzer combined into a single instrument for electromagnetic compatibility compliance testing, product development diagnostics, and pre-compliance measurements. Operating from 9 kHz to 7 GHz, it meets CISPR 16-1-1 standards and delivers 110 dB dynamic range with input sensitivity to –152 dBm across key frequency bands. The instrument supports both conventional stepped frequency scans and FFT-based time-domain scans, the latter significantly accelerating measurement cycles. Its weighting detectors—including CISPR, QPK, PK+, and RMS average—enable direct comparison with regulatory limit values, while configurable markers, IF analysis, and spectrogram display provide detailed signal characterization for laboratory and field applications.
