Keysight offers a family of single-ended passive probes offers the performance expected of an active probe with the usability expected from a passive probe. The Hi-Z+ probes support higher input voltages and support for simplified probing of MMCX connectors. All three of these probes leverage the PP0004A Hi-Z+ Adapter to interface with our current generation oscilloscopes with AutoProbe 1 interfaces. There are also a variety of accessory kits available for extra parts or replacements.
