• Probe Types

    Keysight offers a broad range of voltage, current, and optical probing solutions for InfiniiVision and Infiniium Series oscilloscopes. Select from the probe categories listed below to see what Keysight has to offer.

    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.

    AutoProbe1 Oscilloscope
    1. When using a power adapter booster (standard). 15 A-Pk, 5 V-RMS without oscilloscope-provided power only. An MXR/EXR enables max current range without using the power adapter.
    2. Auto-selected based on Amps/division setting.
    3. The maximum number of current probes supported by InfiniiVision oscilloscopes is limited depending on the oscilloscope. Infiniium oscilloscopes have no limitations.
    4. Manually selectable.?
    5. A wider input range is possible when using the user-defined head and Rsense.
