Rohde & Schwarz URV5-Z1 DC Probe

The Rohde & Schwarz URV5-Z1 DC Probe is a precision DC voltage measurement accessory engineered for high-frequency and RF circuit applications. It connects directly to URV5 series power meters and millivoltmeters, delivering stable measurements without circuit loading. The probe’s 9 MΩ input impedance and 6 pF input capacitance preserve circuit operating points and eliminate capacitive interaction—critical for active circuit characterization.

Measure DC voltages from 0 to 400 V with minimal impact on the circuit under test. Integrated calibration data stored within the probe enables direct connection to compatible Rohde & Schwarz instruments without manual adjustment. The 1.2 m connecting cable, compact 15 mm diameter × 125 mm length design, and included ground cable, clamp-on tip, and BNC adapter support flexible bench and production setups.
