For Infiniium Series Oscilloscope

Technical overview

MIPI® DigRFSM v4 (M-PHY®)

MIPI serial buses are the backbone for communication in mobile products. The serial bus interface provides content-rich points for debug and test. However, since these protocols transfer bits serially, using a traditional oscilloscope has limitations. Manually converting captured 1’s and 0’s to protocol requires significant effort, can’t be done in real-time, and includes potential for human error. As well, traditional scope triggers are not sufficient for specifying protocol-level conditions. Extend your scope capability with the Keysight Technologies, Inc. MIPI DigRF v4 (M-PHY) triggering and decode application. This application makes it easy to debug and test designs that include MIPI DigRF v4 buses using your Infiniium Series oscilloscope.  

– Set up your scope to show MIPI DigRFv4 protocol decode in less than 1 minute.

– Get access to a rich set of integrated protocol-level triggers.

– Save time and eliminate errors by viewing packets at the protocol level.

– Use time-correlated views to quickly troubleshoot serial protocol problems back to their timing or signal integrity root cause.

MIPI DigRF v4 (M-PHY) Setup, Protocol Triggering and Search Capabilities

Get access to a rich set of integrated protocol-level triggers. The application includes a suite of configurable protocol-level trigger conditions specific to MIPI DigRF v4. When serial triggering is selected, the application uses software-based triggering. With software-based protocol triggering, the oscilloscope takes signals acquired using scope channels and reconstructs protocol frames after each acquisition. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

MIPI DigRF v4 (M-PHY) Protocol Decode 

Keysight MIPI DigRF v4 (M-PHY) protocol decoder software supports both high speed (HS-BURST) and low speed (SYS-BURST) modes on Tx and Rx packets. Also, decodes with or without cyclical redundancy check (CRC) support.
