The Yokogawa 701949 is a miniature passive probe engineered for high-frequency signal measurement with oscilloscopes operating from DC to 500 MHz. Built with a 10:1 attenuation ratio and rated for maximum input voltage of 400 Vrms, this probe delivers precise waveform acquisition across a broad bandwidth with minimal loading effects on the circuit under test. The compact, lightweight design incorporates a spring-loaded contact tip that reduces stress on sensitive components while enabling access to densely populated PCBs and ICs. With 10 MΩ input resistance, 9.5 pF typical input capacitance, and 700 ps rise time, the probe provides clean signal fidelity for transient and frequency-domain analysis. A 1.3 meter cable length supports flexible test setups, and the included accessory kit addresses common IC and PCB measurement scenarios.

– Compatibility & Integration
This probe is specified for use with Yokogawa oscilloscope series: DLM3000, DLM5000, DLM5000HD, DLM4000, DLM6000, DL9000, DL9500, DL9700, SB5000, DL6000, and DLM2000. Oscilloscope input impedance must be set to 1 MΩ. Manual attenuation ratio adjustment to 10:1 may be required if automatic detection is unavailable. Not suitable for differential voltage measurements between floating nodes or operation in wet, damp, or hazardous environments.
