Siglent DPB5700A: High-Voltage Differential Probe for Precision Measurements

Siglent DPB5700A High Voltage Differential Probe (100 MHz / 7000V)

The Siglent DPB5700A is a high-performance 100 MHz high-voltage differential probe designed for safe, accurate measurement of floating and high-potential signals. With a maximum differential voltage of 7000V (DC + Peak AC) and dual attenuation ranges (100X / 1000X), it is ideal for high-voltage power electronics testing, inverter development, motor drive research, and advanced switching power supply diagnostics.

Engineered for professional test environments, the DPB5700A offers excellent CMRR performance, fast 3.5 ns rise time, and CAT III / CAT II safety ratings, ensuring precise and safe measurement when paired with modern oscilloscopes. For applications requiring alternative voltage ranges or bandwidths, users may also consider the Siglent DPB5150A  — a versatile 1500V, 100MHz option suitable for power electronics and general test labs.
