Micsig DP Series High Voltage Differential Probe
MICSIG 麦科信
Product Overview
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-zeroing 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.
Product Features
Excellent amplitude frequency characteristics: The amplitude fluctuation within half bandwidth is less than 0.5dB, achieving excellent bandwidth flatness and maintaining high accuracy in high frequency bands.
High Accuracy, High CMRR: DP series has 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 high common mode voltage at high frequencies.
Low Noise: The extremely low noise floor enhances the sensitivity of measurement and can accurately measure small signal changes.
5MHz Bandwidth Limit: (*Available on 100-200MHz bandwidth only) When measuring FET switching frequency in most switching power supplies, it could effectively eliminate high frequency noise.
BNC Interface: Standard BNC interface, works with any oscilloscope.
Stronger anti-interference ability: Built-in strong metal shielding, more durable, and have stronger anti-interference ability.
