SVID Protocol Triggering and Decode for Infiniium Series Oscilloscopes

SVID

SerialVID is a three wire (clock, data, alert) serial synchronous interface used to transfer power management information between a master (typically a microprocessor) and a slave (typically a voltage regulator controller). The bus will operate at a maximum frequency of 26.25 MHz. 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. SVID triggering and decode application. This application makes it easy to debug and test designs that include SVID buses using your Infiniium Series oscilloscope.

Set up your scope to show SVID protocol decode in less than 30 seconds.

Get access to a rich set of integrated protocol-level (Protocol trigger capability available with the 9000 series oscilloscope).

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.

Easy to find

Turn decode on/off via the “Serial Decode” button on the front of 9000 Series scopes or in the “Setup” menu. View decode embedded on the waveform display or in the protocol viewer listing window.

SVID 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 SVID. When serial trigger­ing is selected, the application enables special real-time triggering hardware inside the scope. Hardware-based trig­gering ensures that the scope never misses a trigger event when armed. This hardware takes signals acquired using either scope or digital channels and reconstructs proto­col frames. It then inspects these protocol frames against specified protocol-level trigger conditions and triggers when the condition is met.

SVID decode embedded in waveform area

Utilize the oscilloscope waveform area to display decode information. Minor ticks indicate clock transitions and major ticks show segments within each SVID packet.
