Product Description

The Micsig DP Series High Voltage Differential Probes (DP700 / DP1500 / DP3000) provide accurate and safe high-voltage signal measurement for oscilloscopes. Designed for engineers working with power electronics, switching power supplies, motor drives, and industrial systems, these probes deliver excellent signal fidelity with 100MHz bandwidth and superior common-mode noise rejection.

With selectable models supporting up to 700V, 1500V, or 3000V differential voltage, the DP series offers a flexible solution for a wide range of high-voltage testing applications. Its compact, USB-powered design eliminates the need for bulky external power supplies, making it ideal for both laboratory and field diagnostics.

Equipped with a standard BNC output, the probe is compatible with most oscilloscopes from major brands including Tektronix, Keysight, Rigol, Siglent, Hantek, and more.

Key Features

High Voltage Differential Measurement

Supports safe differential voltage measurements with three selectable models:

• DP700 – up to 700V

• DP1500 – up to 1500V

• DP3000 – up to 3000V

Ideal for analyzing high-voltage circuits and floating signals.

100MHz Bandwidth for Accurate Waveforms

With 100MHz bandwidth and fast rise time, the probe captures high-speed switching signals with excellent accuracy.

Adjustable Attenuation Range

Selectable 20X – 200X attenuation with ±2% accuracy allows flexible measurement across various voltage ranges.

Excellent Noise Rejection

High Common Mode Rejection Ratio (CMRR) ensures stable measurements even in electrically noisy environments:

• 80dB (DC)

• 60dB @ 100kHz

• 30dB @ 10MHz

Compact & USB Powered

Powered via USB 5V, the probe eliminates the need for an external power adapter. The compact and lightweight design makes it ideal for portable diagnostics and bench testing.

Built-in Safety Protection

Integrated over-voltage alarm with LED indicator provides additional safety during high-voltage measurements.

Flexible Cable Length

Includes long 45cm input leads and 90cm output cable, allowing convenient access to test points in complex setups.
