Micsig DP Series High Voltage Differential Probe
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.
[Description of Amplitude-Frequency Characteristic Curve Graph]: The graph shows Gain Loss in dB versus Frequency in MHz, illustrating the probe's performance across different frequencies with minimal fluctuation.
High Accuracy, High CMRR
DP series probes feature high input impedance and low input capacitance, minimizing load effects and greatly improving the accuracy of differential signal measurements. They offer high common-mode rejection capability, suitable for floating measurements of high common-mode voltage at high frequencies.
[Description of Oscilloscope Measurement 1]: Shows a differential signal measurement at 100MHz with 6.354V amplitude. The output common mode signal amplitude is 223.1mV, indicating a CMRR of -29dB.
[Description of Oscilloscope Measurement 2]: Shows a differential signal measurement at 100KHz with 207.7V amplitude. The output common mode signal amplitude is 94.62mV, indicating a CMRR greater than -70dB.
Low Noise
The extremely low noise floor enhances measurement sensitivity, allowing for accurate measurement of small signal changes.
[Description of Low Noise Oscilloscope Measurement]: Shows a measurement with a noise floor of 339.6μVrms at 500X, full bandwidth (300MHz).
5MHz Bandwidth Limit
(*Available on 100-200MHz bandwidth models only). When measuring FET switching frequency in most switching power supplies, this limit effectively eliminates high-frequency noise.
BNC Interface
Features a standard BNC interface for compatibility with any oscilloscope.
Stronger Anti-Interference Ability
Built-in strong metal shielding provides increased durability and enhanced anti-interference performance.
