PS00xxA Optical Isolated Differential Probes and Accessories Streamline Safe, Isolated Insight Information.

Electrically isolated voltage probes isolate the test equipment (DUT) from the oscilloscope.

Ground, enabling safer and more accurate measurements. This isolation effectively eliminates interference.

Common mode signals minimize noise interference and eliminate ground loops in high-voltage systems.

Environment. High Common Mode Rejection Ratio (CMRR) is crucial for capturing tiny signals.

Accuracy, even when floating nodes have large common-mode voltages.

The sensitivity of isolated probes can be over 100 million times higher than standard differential voltage probes.

Reference to Earth Grounding.

In addition to high CMRR and enhanced safety, isolated probes offer additional advantages over standard probes.

Differential probes. Their isolation characteristics make them less susceptible to electromagnetic interference (EMI).

Reduced signal distortion. Additionally, Gisly's isolated probes support higher offset voltages.

At higher bandwidths, a wider differential voltage range ensures precise measurements during fast switchovers.

Signal and transient phenomena occurring in noisy, high common-mode environments.
