High Voltage Differential Probe DP700

The DP700 is a high-performance high voltage differential probe from the DP Series, designed for safe and accurate measurement of high-voltage differential signals in demanding electronic applications. Featuring a bandwidth of 100MHz and a maximum differential input voltage of 70V (20X) or 700V (200X), it is engineered to deliver reliable performance in high-frequency, high-voltage environments. The probe adopts an innovative integrated host design, consolidating signal input, control buttons, and BNC output into a compact unit for easier deployment and use. Its high input impedance (6MΩ differential, 3MΩ to ground per side) and low input capacitance (1.67pF differential) effectively suppress loading effects on the circuit under test, ensuring measurement integrity. Key attributes include an excellent common-mode rejection ratio (CMRR), low noise floor for sensitive small-signal measurements, and a one-button zero calibration function for quick setup. With dual power supply options (DC5V and Type-C) and support for command programming, the DP700 is versatile for both manual and automated test scenarios. It is an ideal tool for debugging and testing in New Energy Vehicle power systems, photovoltaic inverters, switching power supplies, and other power electronics applications.

Key Features

• High Bandwidth & Voltage Range: 100MHz bandwidth with maximum input voltages of 70V (20X) and 700V (200X).
• High Accuracy & Low Noise: Typical accuracy of ±2% (customizable to ±1%). Low noise floor (20X: <20mVrms; 200X: <90mVrms) enables precise measurement of small signal variations.
• Excellent CMRR: High common-mode rejection ratio (>-80dB at DC, >-60dB at 100kHz) ensures accurate measurements in noisy environments.
• High Impedance, Low Capacitance Input: 6MΩ / 1.67pF differential input minimizes circuit loading and preserves signal fidelity.
• Convenient Operation: Features one-touch zero calibration, dual-range selection, overload alarm (LED and buzzer), and range power-off memory.
• Flexible Power & Control: Dual power supply ports (DC5V and Type-C) for mobility. Supports command programming for automated testing.
• Noise Suppression: Built-in 5MHz bandwidth limit function to filter out high-frequency noise for cleaner waveforms.
