High-frequency test probe DP1500

electricinterface

Overview
The DP1500 is a high-performance high-voltage differential probe engineered for precise differential voltage measurement in high-voltage, high-frequency environments. With 100 MHz bandwidth and a maximum input differential voltage of 1500 Vpk (500X attenuation) it is suitable for applications such as new energy vehicle power systems, photovoltaic inverters and switching power supply design. The probe provides high input impedance and low input capacitance to reduce loading and noise, and supports DC 5V and USB Type-C power options, one-touch zero calibration, dual-range selection and a 5 MHz bandwidth limit. Overload indication and command programming control enable integration into automated test systems. The DP1500 is supplied with a comprehensive accessory kit for immediate deployment.

Key Features

• High voltage & high bandwidth: 1500 Vpk max input, 100 MHz bandwidth for high-frequency high-voltage testing.
• Dual range selection: 500X and 50X attenuation options to match test levels.
• One-touch zero calibration: fast offset calibration before measurements.
• 5 MHz bandwidth limit: reduces high-frequency noise for clearer waveform display.
• Dual power supply ports: supports DC 5V and USB Type-C for flexible operation.
• Command programming control: integration into automated test setups.
• High CMRR: > -80 dB at DC, > -60 dB at 100 kHz, ensuring accurate differential measurements.
• Low noise floor: < 50 mVrms at 50X improving sensitivity for small signal changes.
• Compact integrated design: all functions contained in a single unit for easy deployment.
