Yokogawa 701944/701945 100:1 High Voltage Probe

When the rise time of the probe is 10%~90%, it is less than 900ps. When it is 10%~90%, it is less than 1.4ns. The shorter the rise time, the faster the high-frequency signal response

The maximum input voltage is 1000Vrms. The voltage derating curve should be referenced for 1000Vrms, and the input voltage should be reduced at high frequencies

System input resistance 50M Ω± 1% 50M Ω± 1% ensures matching with oscilloscope input impedance

The typical value of system input capacitance is 7.5pF, which affects the stability of high-frequency signal measurement

Compensation range typical value 10pF~25pF typical value 10pF~25pF adapted to different oscilloscope input capacitors

（2） Mechanical and environmental parameters

Weight: The probe body weighs about 55g, lightweight and easy to operate, reducing fatigue from prolonged use.

Cable length: 701944 is about 1.2m, 701945 is about 3m, suitable for different measurement distance requirements. The long cable model (701945) is more suitable for long-distance measurement scenarios.

Protection standard: Complies with EN 61010-031 safety standard, measurement category II, transient voltage 4000V; complies with the EU RoHS directive, environmentally friendly and free of harmful substances.

Input impedance characteristics: It decreases with the increase of input signal frequency, and reference should be made to the "input impedance curve". When measuring at high frequencies, attention should be paid to the impact of impedance changes on the measurement results.
