The Siglent DPB5150 is a 70 MHz differential high-voltage probe engineered for precise measurements in power electronics and industrial environments. With a fast rise time of ≤5 ns and dual attenuation ratios of 50X and 500X, it supports differential voltage measurements up to 1500 V (DC + peak AC) and provides excellent accuracy of ±2%. The probe features high input impedance (10 MΩ differential) and low input capacitance (<2 pF), minimizing loading effects and preserving signal integrity. It offers excellent CMRR performance, with >80 dB at DC and >50 dB at 1 MHz, ensuring reliable differential signal capture in noisy environments. Powered via USB (5 V/1 A), the DPB5150 is ideal for engineers analyzing switching power supplies, inverters, and high-voltage differential circuits.
