The Yokogawa 701938 is a 10:1 passive probe engineered for precision voltage measurement on Yokogawa oscilloscopes up to 200 MHz. Rated for 600 V (DC + ACpeak) or 424 Vrms, this probe delivers the input impedance and capacitance matching required for accurate waveform acquisition across moderate-frequency and high-voltage applications.
– Technical Specifications
• Bandwidth: DC to 200 MHz (−3 dB)
• Attenuation Ratio: 10:1
• Input Resistance: 10 MΩ ±2% (with 1 MΩ ±1% oscilloscope input impedance)
• Input Capacitance: Approximately 13.5 pF (with 1 MΩ ±1% oscilloscope input impedance)
• Maximum Input Voltage: 600 V (DC + ACpeak) or 424 Vrms
• Rise Time: 1.75 ns maximum (typical)
• Coaxial Cable Length: 1.5 meters
– Key Features
• 10:1 attenuation minimizes loading effects on test circuits
• Matched impedance termination ensures flat frequency response to 200 MHz
• Color-coded options (yellow, green, magenta, cyan, red, orange, light blue, purple) enable circuit-specific identification
• Included ground lead, pinchers tip, IC test tip, ground attachment, and marker tip provide flexible probing configurations
• Capacitance adjustment via trimmer tuning compensates for oscilloscope input characteristics
– Typical Applications
• Power supply and switched-mode power supply (SMPS) testing
• Motor drive and inverter circuit analysis
• Industrial control signal acquisition
• General-purpose analog circuit measurement at moderate frequencies
– Compatibility & Integration
The 701938 is engineered for Yokogawa DLM2000/4000, DL6000, and DLM6000 series oscilloscopes with 1 MΩ input impedance. Before first use, connect the probe to the oscilloscope’s CAL signal output and adjust the trimmer capacitance to obtain the correct calibration waveform. Clean only with a soft cloth; avoid abrasive materials, benzene-based solvents, and immersion. Do not exceed maximum working voltage; contact a Yokogawa dealer if damage is suspected.
