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
