Trigger on the specified data when the timeout condition is meet. When using
SPI trigger, you need to specify the SCL and SDA data sources.
In SPI bus trigger mode, the trigger setting information is displayed on bottom
right of the screen, for example,
SPI, CH1 trigger level is 0.00mV.

4. CAN Trigger
CAN (Controller Area Network) is a serial communication protocol of the ISO
international standardization.
By using the CAN bus trigger, you can trigger on Start of Frame, Type of

Instruction
Set vertical channel bus type as SPI trigger.
Set SCL.
Set SDA.
Set the minimum time that SCL must be idle, that
is a period of SCL, available range 100ns-10s.
Time out means SCL keeps idle for a specified
time before oscilloscope starts to search for the
data (SDA) on which to trigger. Click
set time out, click
which digit to be set.
Means sample the SDA data on the rising edge or
falling edge of the clock.
Set the number of bits of the serial data character
string. It can be set to any integer between 4-32.
