Trigger Setup
Triggering on Buses
You can use your oscilloscope to trigger on CAN, I

C, SPI, RS-232, RS-422 , RS-485, UART, LIN, FlexRay, I

S, Left Justified, Right
Justified, and TDM buses, if you have the appropriate DPO4AUTO, DPO4AUTOMAX, DPO4EMBD, DPO4COMP, or DPO4AUDIO
application module installed. The MSO4000 Series can trigger on parallel buses without an application module. The oscilloscope
can display both physical layer (as analog waveforms) and protocol level information (as digital and symbolic waveforms).
To set up the bus trigger:
1. If you have not already defined your bus using
the front-panel B1 and B2 buttons (and B3 and
B4 on the MSO400 0 Series), do so now. (See
page 100, Setting Up a S erial or Parallel Bus.)
2. Push Trigger Menu.
