DPB5700 Differential High Voltage Probe 70 MHz Bandwidth 7000 V Differential Input 100X 1000X Attenuation

The Siglent DPB5700 is a precision differential high-voltage probe designed for high-performance measurements in demanding applications. With a wide bandwidth of 70 MHz and fast rise time of 5 ns, it accurately captures high-speed differential signals. It offers selectable attenuation ratios of 100× and 1000×, enabling safe measurement of voltages up to 7,000 V peak differential. The probe features high input impedance (up to 40 MΩ) and low input capacitance, minimizing loading on the test circuit. DC accuracy is maintained at ±2% across both ranges. The DPB5700 includes built-in overload protection, LED indicator, audible warning, and auto-save of offset settings. It is powered via a standard USB 5 V/1 A supply and housed in a lightweight, compact enclosure, making it ideal for field or bench use. The body dimensions are approximately 195 × 65 × 28 mm and it ships in a 32 × 26 × 9 cm box. Suitable for high-voltage inverter, converter, and industrial signal testing environments.
