Combining a 16-channel logic analyzer with 4-channel analog inputs, it is suitable for simultaneously monitoring SVID commands and voltage changes of VRMs (Voltage Regulator Modules).

Multiple trigger methods:

  • Use the rising or falling edge of the VRM voltage as the trigger to trace back the protocol content and identify the command that caused the voltage change.

  • Conversely, a specific protocol command can be set as the trigger to observe the corresponding VRM voltage change.


Supported version:

SVID Rev 1.96
