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.

1. Input impedance when terminated into oscilloscopes with 1-MΩ input terminations. For higher-bandwidth Infiniium oscilloscopes with 50-Ω input terminations only, the E2697A high impedance adapter can be purchased (includes 10073D 500-MHz passive probe) to provide a 1-MΩ input termination. 

2. For proper probe compensation (flatness), the oscilloscope’s input capacitance must be within the specified compensation range of the probe. 

3. Capacitance at the probe tip of 1:1 probes is the specified probe capacitance plus the capacitance of the oscilloscope when terminated into 1-MΩ.

4. Input impedance when terminated into oscilloscopes with 50-Ω input terminations. These probes are not compatible with Keysight’s InfiniiVision 1000 and 2000 X-Series oscilloscopes. 

High-Frequency Differential Active Probes < 10 GHz

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.

  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.

AutoProbe1 Interface

Keysight’s AutoProbe1 interface provides the following:

  • DC voltage to power active probe circuitry
  • Automatic detection of probe attenuation
  • Automatic control of selectable probe attenuation on some probes
  • Probe DC offset on many probes

Optical Probes

Keysight offers fully-integrated optical front-end solutions for Infiniium real-time oscilloscopes. The solution is designed for reference receiver testing of industry optical standards or characterizing the raw response of an optical transmitter. It can also be used to view optical streams at speeds up to 56 Gbaud PAM4, making it an ideal solution for characterizing or troubleshooting high-speed optical signals in system level testing and debugging.
