Yokogawa 701944 High Voltage Passive Probe, 1000Vrms, 400 MHz

The Yokogawa 701944 is a high voltage passive probe designed for precision measurement of signals up to 1000 Vrms in demanding electrical and power electronics environments. With a 100:1 attenuation ratio and 400 MHz bandwidth, it captures transient and steady-state behavior across DC and AC circuits. The probe’s 50 MΩ input resistance and 7.5 pF input capacitance minimize circuit loading, while the 1.2 meter coax cable provides practical reach for bench and field measurements.
