Command Groups
Bus Command GroupUse the Bus commands when working with serial or parallel bus measurements.
Install the DPOEMBD application module when working with I2CorSPI
bus signals.
Install the DPO4COMP module when working with RS-232, RS-422,
RS-485, or UART bus signals.
Install the DPO4AUDIO module when working with I2S, Left Justified (LJ),
Right Justified (RJ), or TDM bus signals.
Install the DPO4AUTO or DPO4AUTOMAX module when working with
CAN or LIN bus signals.
Install the DPO4AUTOMAX module when working with FlexRay bus
signals.
NOTE. LIN and FlexRay work on DPO4000s with serial numbers greater than
C020000 and on all MSO4000s.
NOTE. The parallel bus commands work with MSO4000 Series oscilloscopes only.
NOTE. The Search Command Group and theTrigger Command Group also
contain bus-related commands.
