MIPI DigRF v4 (M-PHY) Protocol Triggering and Decode for Infiniium Series Oscilloscopes

MIPI DigRF v4 (M-PHY)

MIPI (Mobile Industry Processor Interface) 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 DigRF v4 protocol decode in less than 30 seconds.
• 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.

The following are the MIPI DigRF v4 protocols and features that will be supported by the application.

1. Supports DigRF v4 v1.00.00 decode and triggering
2. Decodes high-speed (HS-BURST) and low-speed (SYS-BURST) modes
3. Decodes with and without cyclical redundancy check (CRC) support
4. Supports decode on Tx and Rx packets
5. Supports search capability for various frames, sequence and errors

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 either scope or digital 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.
