Keysight’s U7238B MIPI D-PHY compliance test software for Infiniium oscilloscopes enables you with a fast and easy way to validate and debug your embedded D-PHY data links in accordance to the specification and CTS. The D-PHY electrical test software allows you to automatically execute D-PHY electrical checklist tests for CSI-2 and DSI architectures and displays the results in a flexible report format. In addition to the measurement data, the report provides margin analysis that shows how closely your product passed or failed each test.

Used with the automated switching solution, engineers have the ability to:

  • Eliminate reconnections (and errors) -- Simplifies testing by automating tests for each lane of a multilane bus.
  • Maintain accuracy -- Engineers can use Keysight’s unique N2809A PrecisionProbe or N5465A InfiniiSim to compensate switch path losses and skew.
  • Customize testing -- The test application can be extended with remote programming hooks interface and a N5467A user-defined application (N5467A) for device control, equipment control and test customization or scripting.
