KEYSIGHT PS00XXA Optically Isolated Differential Probe Introduction

Posted by Batter Fly 11/04/2025 0 Comment(s) 583

Keysight PS0004A, PS0006A, and PS0008A are part of the PS00XXA series of optically isolated differential probes, designed for high-precision measurements in high-voltage environments. These probes provide galvanic isolation between the device under test (DUT), the oscilloscope, and earth ground, ensuring safer and more accurate measurements by eliminating common-mode signals, reducing noise interference, and preventing ground loops.

The PS00XXA series supports bandwidths ranging from 350 MHz (PS0004A) to 1 GHz (PS0008A) and differential voltage measurements up to ±2,500 V. With a high common-mode rejection ratio (CMRR), these probes excel at capturing small signals even in the presence of large common-mode voltages on floating nodes. Each probe requires a compatible tip, sold separately, to connect the sensor head to the DUT.

Main Features

  • Bandwidth: 350 MHz (PS0004A), 700 MHz (PS0006A), 1 GHz (PS0008A)
  • Cable length: 2 m
  • AutoProbe 1 interface for seamless integration
  • Supports differential measurements up to ±2,500 V
  • High common-mode rejection ratio (CMRR)
  • UL-certified for safety
  • Requires compatible probe tips (sold separately)

Enhanced Measurement Precision

The PS00XXA series ensures accurate measurements of fast-switching signals and transients in noisy environments. Its optical isolation minimizes electromagnetic interference (EMI) while supporting higher offset voltages and broader differential voltage ranges. Whether used for high-voltage testing or sensitive signal analysis, these probes deliver reliable performance.
