The Rohde & Schwarz URV5 (394.8010.02) is a precision RF voltmeter for broadband voltage, level, and power measurements spanning DC to 26.5 GHz. It delivers ±1% basic accuracy through microprocessor-controlled error correction and maintains a dynamic range exceeding 94 dB. The instrument accommodates two test inputs and supports modular probe and sensor configurations, making it suitable for both standalone operation and automated test system integration.
