The Rohde & Schwarz ESVP is a programmable measuring receiver for signal analysis and interference detection across 20 MHz to 1.3 GHz. Built for EMC testing, radiomonitoring, and radio communication analysis, it delivers amplitude measurements from -20 dBm to +137 dBµV with sub-1 dB accuracy and dynamic range exceeding 100 dB. The instrument supports selective voltage and two-port measurements across AM, FM, PM, SSB, ASK, FSK, PSK, and QAM modulations, with demodulation bandwidth spanning 1 Hz to 10 MHz and IF bandwidth options from 10 Hz to 10 MHz. Frequency setting resolution reaches 100 Hz in SSB mode with frequency error below 5 × 10⁻⁹ (maximum 5 kHz at 1 GHz), improving to 2 × 10⁻⁹ with the optional oven-controlled crystal oscillator.
