Quick Guide
High Voltage Differential Probe -- MDP series
Bandwidth: 300MHz / 400MHz / 500MHz
1. Overview
Originated from Micsig’s cutting-edge SigOFITTM technology, the MDP series high-
voltage 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
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.

4. Precautions
1) Calibrate the probe before use:
Short-circuit the input ends, power on, press “Zero” button, Range indicator
lights flash alternately; if hearing a “Di” sound, means calibration succeeded; if
hearing a “DiDiDi” sound, means calibration failed, needs to recalibration;
2) The bandwidth of the oscilloscope should be no less than the bandwidth of
the probe, channel input impedance should be 50Ω.
3) Recommend to use after 10 minutes warm-up to get more accurate result.
4) When Range LED indicator flashes and beeps rapidly, indicating Over-
voltage warning, please switch to higher range.
