The Rohde & Schwarz ESPC is a dedicated EMI test receiver for EMC compliance measurement across 150 kHz to 1 GHz. It delivers parallel detection of Average, Peak, and Quasi-Peak signals with correct CISPR 16-1 interference weighting down to 10 Hz pulse repetition frequency. The instrument combines fast frequency synthesis, multiple IF bandwidths (200 Hz, 9 kHz, 120 kHz, 1 MHz), and 80 dB dynamic range to characterize emissions in voltage, field strength, current, and pulse spectral density formats.
