The Rohde & Schwarz ESVP52 is a programmable test receiver for RF and microwave measurements across signal monitoring, interference analysis, EMC testing, and component validation in laboratory and production environments. Operating from 20 MHz to 1300 MHz with a measurement range of −20 dBµV to +137 dBµV, the instrument delivers selective voltage and two-port measurements essential for automated test systems. Its dual-conversion architecture employs 1st intermediate frequencies of 810.7/310.7 MHz and a 2nd IF of 10.7 MHz, with selectable bandwidths of 7.5 kHz, 12 kHz, 120 kHz, and 1 MHz. Tuning resolution spans 100 kHz, 10 kHz, or 1 kHz steps for precise frequency definition.
