Hi-Z+ PASSIVE PROBING SYSTEM
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.

Power Rail Probes
Measure Output Ripple with High-Sensitivity
Engineers often use 1:1 passive probes for the sensitivity required to measure the output ripple of DC supplies. But 1:1 passive probes have limited bandwidth (typically less than 35 MHz) and no DC offset capability. A Keysight power rail probe can measure noise, output ripple, and transients on DC power supplies with high sensitivity (millivolts), large DC offsets, and high bandwidth.
