Tips for PS000XA Series Probe Pods

The main structure of the PS000xA series of isolated probes include a probe pod and a sensor head. The pod features the AutoProbe 1 interface, which connects to the oscilloscope input. To measure, a probe tip like the PS0025A is needed to link the sensor head to the device under test (DUT). Probe tips are sold separately from the pod and come in different voltage ratings and connector types (MMCX, 100 Mil or 200 Mil Sockets). The family of PS000xA probes are compatible with Keysight's Infiniium EXR-Series, MXR B-Series and InfiniiVision HD3 Series of oscilloscopes.

Tip Series Performance Guide

The electrical ratings listed below apply solely to the probe tips. Since each isolated probe must be used with a probe tip, the lower of the two electrical ratings should be considered when used together. The specifications reflect both guaranteed (as indicated) and typical performance after a recommended warm-up period of 30 minutes.

1- Denotes a warranted specification using the PS0008A 1 GHz isolated probe with the PS0017A 10 V MMCX probe tip. All other measurements are typical.

3 Denotes a warranted specification using the PS0008A 1 GHz isolated probe with the PS0017A 10 V MMCX probe tip as per the performance verification procedure outlined in the User Guide. All other measurements are typical.

4 (a) Derated with frequency. See voltage derating curves. (b) View the diagram in Figure 9 to compare input voltage ranges.

5- If an optically isolated probe is held with a non-conducting probe holder that has virtually no DC leakage to the surrounding environment (i.e. very high resistance) then the DC CMRR becomes unmeasurable in practice and is considered nearly infinite.

6- View the User Guide for connector dimensions.

PS000xA Series of Optically Isolated Differential Probes

Three models are available to choose from in the PS000XA family of probe pods to pair with the tips. Galvanically isolated voltage probes provide separation between the device under test (DUT) and the oscilloscope, as well as earth ground, allowing for safer and more precise measurements. This isolation effectively blocks common-mode signals, reduces noise interference, and prevents ground loops in high-voltage settings. A high common-mode rejection ratio (CMRR) is crucial for accurately detecting small signals, even amidst large common-mode voltages at floating nodes. The CMRR of an isolated probe can be over 100 million times higher than that of a standard differential voltage probe referenced to earth ground.

In addition to high CMRR and improved safety, isolated probes offer further benefits compared to standard differential probes. Their isolation makes them less prone to electromagnetic interference (EMI), decreasing signal distortion. Moreover, Keysight’s isolated probes support higher offset voltages and broader differential voltage ranges at higher bandwidths, ensuring accurate measurements of fast-switching signals and transients in noisy, high-common-mode environments.
