Description

DP Series

Product Details

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.

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

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.

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

Compact & Exquisite
Much smaller than traditional differential probes.
