  • Variable clock input

Stimulus Probe Features

  • Deterministic D-PHY, DSI, and CSI-2 pattern generation
  • Configurable traffic can be generated from the interface or from CSV files
  • Timing control of MIPI D-PHY link layer events
  • Captured logic analyzer trace converted to digital stimulus

Methods for Creating Stimulus

  • Custom programming package
  • Bit level to picture level stimulus generation
  • Captured logic analyzer trace converted to digital stimulus

Configuration Considerations

  • Requires probe N4851A MIPI D-PHY Digital Acquisition Probe
  • Requires 16800 or 16900 Series 68-channel (or more) logic analyzer with a pattern generator
  • Connects to target using SMA (m-m) connectors
  • Refer to data sheet for more information


The N4851A MIPI D-PHY acquisition probe and N4861A MIPI D-PHY stimulus probe enable users to perform real-time digital serial analysis and generate real-time digital serial stimulus of the MIPI D-PHY interface.

Both probes support the CSI-2 (Camera Serial interface) and DSI (Display Serial Interface), enabling users to comprehensively characterize the behavior of controllers as well as display or camera devices.

The Keysight Technologies N4851A acquisition probe and the N4861A stimulus probe operate in conjunction with Keysight 16800 and 16900 Series logic analyzers to provide the digital serial stimulus and acquisition capabilities required to independently debug and test MIPI D-PHY components , or integrate your MIPI D-PHY based mobile designs.
