DPB4080 Differential High Voltage Probe 50 MHz Bandwidth 800 V Input 10X100X Attenuation

The DPB4080 is a professional-grade differential high-voltage probe from Siglent offering up to 50 MHz bandwidth and supporting maximum input differential voltage of 800 V (DC + peak AC). Designed for safe and accurate voltage measurement, it features selectable attenuation ratios of 10X or 100X, converting the input differential voltage into a low-voltage signal (≤ 8 V). With ±1% accuracy, it’s powered by a standard 9 V/1 A DC adapter. Compact and rugged, the probe includes built-in overload indicator and safety features to protect both user and instrumentation. Packaged dimensions are 32 × 26 × 9 cm. Ideal for lab, industrial, and power electronics testing where high-voltage differential signals are present.
