The Siglent DPB5700A is a high-performance 100 MHz differential high-voltage probe, ideal for applications requiring accurate floating signal measurements. Engineered for safety and precision, it supports a maximum differential test voltage of ±1300 V at 500X attenuation and ±130 V at 50X. The input impedance is 20 MΩ single-ended and 40 MΩ differential, minimizing circuit loading, while input capacitance remains below 5 pF and 2.5 pF respectively. With a common-mode voltage rating of 600 V CAT III and 1000 V CAT II, it ensures reliable operation in demanding environments. The probe features a rise time of ≤3.5 ns, excellent CMRR performance of >80 dB at DC, and includes an overload alarm and visual indicator for added protection. Powered by a USB 5 V/1 A adapter, it includes offset adjustment and automatic save functions. The compact body weighs approximately 165 g and measures 165×69×26 mm.
