Micsig DP3003 300MHz ±3000V High Voltage Differential Probe

Description

Originating from Micsig’s cutting-edge SigOFIT ™ technology, the DP series high-voltage differential probes have a very low noise floor, excellent amplitude-frequency characteristics, and industry-leading common mode rejection capability, allowing users to test high-frequency and high-voltage signals with ease.

5MHz Bandwidth Limit

When measuring FET switching frequency in most switching power supplies, the DP probe’s switchable 5MHz filter effectively eliminates high-frequency noise.

Quick Zero

The probe can be zeroed very quickly:  just short-circuit the test leads and press the Zero button.

Dual Range Selection Capability

Improves signal-to-noise ratio, suits more test situations.

BNC Interface

Standard BNC interface, works with any oscilloscope.

USB Power Supply

Powered directly by oscilloscope’s USB port via type-C cable.

Overvoltage Alarm

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

Compact & Exquisite

Much smaller than traditional differential probes.

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

Short circuit the input ends, connect to CH1. Set both attenuation ratio at 50X, vertical scale at 250mV/div, time base at 1ms, input impedance is 1MΩ, observe the noise floor:

* Noise: 40.62mV (RMS) at full bandwidth
