10.1.1 Configuration - General Settings
For all protocols, configuration starts with the selection of the serial bus and the protocol.
The "Trigger Setup" button leads directly to the trigger configuration.
Protocol-specific configuration settings are described in the protocol chapters:
● I²C: chapter 10.2.3.1, "I²C Configuration", on page 260
● SPI: chapter 10.3.3.1, "SPI Configuration", on page 271
● UART: chapter 10.4.2.1, "UART Configuration", on page 279
● LIN: chapter 10.6.2.1, "LIN Configuration", on page 297
● CAN: chapter 10.5.1.1, "CAN Configuration", on page 286
● FlexRay: chapter 10.7.1.1, "FlexRay Configuration", on page 307
Make sure that the tab of the correct serial bus is selected on the left side.
Protocol
Defines protocol type of the bus for bus configuration and trigger settings.
SCPI command:
BUS<m>:TYPE on page 643
Decode
Enables the decoding of the selected bus. The signal icon appears on the signal bar.
This function is only available if at least one protocol option is installed. For triggering on
I²C, SPI, and UART signals, the bus can be used as trigger source without any option,
provided that the bus is configured correctly.
SCPI command:
BUS<m>[:STATe] on page 644
10.1.2 Display
For all protocols, you can select to display the decoded signal as a table and to show the
binary signal on the screen. Optionally, you can assign a label to the bus.
