The Yokogawa 701939 is a 500 MHz passive probe engineered for precision signal acquisition across DC to 500 MHz bandwidth. Rated for 600 V maximum input (DC + AC peak) or 424 Vrms CAT II, this 10:1 attenuation probe delivers 700 ps maximum rise time and 10.5 pF input capacitance when paired with 1 MΩ oscilloscope inputs. The 1.3 meter coaxial cable integrates with Yokogawa’s DLM2000, DLM4000, DL6000, and DLM6000 series instruments via automatic probe ID recognition.

– Compatibility & Integration
Designed for Yokogawa oscilloscopes with 1 MΩ input impedance. Direct compatibility confirmed with DLM2000, DLM4000, DL6000, and DLM6000 series. Ground the oscilloscope’s protective terminal and connect the probe ground lead to measurement reference potential. Do not use for floating voltage measurements or main power supply analysis—differential probes required for floating applications.
