Micsig MDP703 High Voltage Differential Probe User Guide

Quick Guide
High Voltage Differential Probe — MDP series
Bandwidth: 100MHz / 150MHz / 200MHz

Overview

Originated from Micsig’s cutting-edge SigOFIT technology, the MDP series highvoltage differential probe has very low noise floor, excellent amplitude- frequency characteristics and industry-leading common mode rejection capability, allow users to test high-frequency and high-voltage signals with ease.

* Extension leads, twist together can lower noise

Precautions

1. Calibrate the probe before use:
   Short-circuit the input ends, power on, press “Zero” button, 5MHz LED light flashes, after hearing a “Di” sound, means calibration succeeded; if hearing “Di Di Di” sound, means calibration failed, needs to be calibrated again;

2. The bandwidth of the oscilloscope should be no less than the bandwidth of the probe, channel input impedance should be 1MΩ.

3. Recommend to use after 10 mins warm-up to get more accurate result.

4. When Range LED indicator flashes and beeps rapidly, indicating Overvoltage warning, please switch to higher range.

Operation Steps

1. Power the probe: Connect the probe to the oscilloscope USB via USB-C cable;
2. Connect to oscilloscope: Connect the BNC end of the probe to oscilloscope channel (make sure the oscilloscope is grounded);
3. Select Range: Select appropriate voltage range according to the signal;
4. Connect the DUT: Use clips or hooks to connect the DUT, if an over-voltage alarm occurs, disconnect the power supply and the circuit immediately;
5. Set on the oscilloscope.
   *Note: Try not to use extension leads when measuring, it could bring more noise floor. If must use the extension leads, please twist the leads together to reduce noise, and the input frequency should not exceed 5MHz. If it exceeds 5MHz, the output will have a certain error.
