DPB5700A Differential High Voltage Probe 100 MHz Bandwidth 7000 V Differential Input 100X 1000X Attenuation

The Siglent DPB5700A is an advanced differential high‑voltage probe in the DPB5000 series, ideal for floating voltage measurement in high-power electronics, converters, and industrial environments. It offers a 100 MHz bandwidth with a rise time of ≤ 3.5 ns, and supports maximum differential input voltages up to 7,000 V (DC + AC peak). The probe features switchable attenuation ratios of 100× or 1000×, converting measured voltages to a safe ±8 V maximum output. With ±2% DC accuracy, ultra-low input capacitance (≤ 2.5 pF differential), and high input impedance (20 MΩ single‑ended, 40 MΩ differential), it minimizes circuit loading while delivering precise signals. Designed with safety and usability in mind, the DPB5700A includes built-in overload detection, an LED indicator, an audible alarm, automatic offset memory, and optional 5 MHz bandwidth limit mode. Powered via a standard USB 5 V/1 A adapter, the lightweight probe head (~190 g) measures roughly 195 × 65 × 28 mm, and is packaged in a 32 × 26 × 9 cm box with accessories. Compatible with standard oscilloscopes via BNC output, it’s built for durability and field use.
