Rohde & Schwarz URV5 9KHz-26.5GHz Millivoltmeter

The Rohde & Schwarz URV5 is a precision millivoltmeter for voltage, level, and power measurements spanning DC through 26.5 GHz. It delivers ±1% accuracy across a dynamic range exceeding 94 dB, supporting both standalone operation and integration into automated test systems via IEC/IEEE-bus interface. The instrument measures voltages from 200 µV to 1000 V and power from 4 nW to 2 kW (50 Ω), with measurement rates up to 30 readings per second and microprocessor-controlled error correction.
