Micsig DP Series High Voltage Differential Probe Leader

Overview

Micsig high-voltage differential probe — DP series covering bandwidth from 100MHz to 500MHz, differential voltage up to 7000Vpk. Based on the leading optical isolation probe technology, the DP series has very low noise, excellent amplitude-frequency characteristics and high CMRR. With standard BNC interface, the DP series can work with any oscilloscope; probe body is only 2cm thick, protected by metal housing, achieves strong anti-interference ability. One-press auto Zero, dual-range and overload alarm design. High impedance designed, the single-ended impedance of the input end to the signal output BNC interface > 8MΩ, single-ended capacitance < 8pF, meets various safety test requirements. 5MHz bandwidth limit function can effectively filter out high-frequency noise and interference, ideal for switching power supplies, various high-frequency and high-voltage floating or isolated signal tests.

Appearance

DP differential probe mainly consists of control module and signal box.

Control Module

Precautions

The bandwidth of the oscilloscope should be no less than the bandwidth of the probe, channel input impedance should be 50Ω.
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;
Recommend to use after 10 mins warm-up to get more accurate result.
When Range LED indicator flashes and beeps rapidly, indicating an Overvoltage warning, please switch to higher range.

Operation Steps

Power the probe: Power the probe with standard adapter;
Connect to oscilloscope: Connect the BNC end of the probe to oscilloscope channel (make sure the oscilloscope is grounded);
Select Range: Select appropriate voltage range according to the signal;
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;
Set on the oscilloscope: Set input impedance to 50Ω, adjust the channel attenuation ratio.
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.
