Micsig dp series

The Micsig DP Series High-Voltage Differential Probes offer selectable bandwidths ranging from 100MHz to 500MHz, with a maximum differential input voltage of 7000Vpk.A standard BNC interface ensures compatibility with all major oscilloscope brands. Built-in metal shielding enhances anti-interference performance. With a compact 2cm-thin design, the probes save workspace and feature one-click auto-zero for quick setup. Additional functions include overload protection alarms and power-off memory for seamless operation. A high-impedance input and low input capacitance minimize loading effects, delivering ±2% measurement accuracy and excellent common-mode rejection (CMRR). Ideal for EV power systems, solar inverters, switching power supplies, and floating or isolated high-voltage signal testing.

Excellent Bandwidth Flatness


The DP series probe has excellent bandwidth flatness, amplitude fluctuation less than 0.5dB within its half bandwidth range, even in high frequency bands can also maintain high accuracy.

differential probe

High Accuracy, High CMRR


High input impedance and low input capacitance, minimized load effect, greatly improved the accuracy of the differential signal. High common mode rejection capability, able to meet floating measurements of large common mode voltage at high frequencies.


CH1: @ 100KHz, 207.7V, output common mode signal amplitude 94.62mV, CMRR > -60dB

differential probe

Low Noise


DP3000 test results: noise at full bandwidth is 254.8μVrms.

5MHz Bandwidth Limit 

(only available on 100MHz ~ 200MHz versions)

When measuring FET switching frequency in most switching power supplies, DP probe effectively eliminates high-frequency noise.


Quick Zero

Short-circuit the test leads, press Zero button, the probe can be zeroed very fast.


Dual Range Selection

Improves signal-to-noise ratio, meet more test requirements.


BNC Interface

Standard BNC interface, work with any oscilloscope.


differential probe

Overvoltage Alarm

LED flashes, buzzer "beeps" rapidly, indicating an over-range alert.


Compact & Exquisite

Much smaller than traditional differential probes.

Built-in metal shielding enhances anti-interference performance. With a compact 2cm-thin design, the probes save workspace and feature one-click auto-zero for quick setup. Additional functions include overload protection alarms and power-off memory for seamless operation.


An ultra-low noise floor (as low as 5mVrms) and dual-range design optimize the signal-to-noise ratio across different voltage levels. A high-impedance input and low input capacitance minimize loading effects, delivering ±2% measurement accuracy and excellent common-mode rejection (CMRR).


The 5MHz bandwidth limit reduces high-frequency noise for accurate, high-speed differential voltage measurements. Ideal for EV power systems, solar inverters, switching power supplies, and floating or isolated high-voltage signal testing.
