Source (Source)
Select the trigger source. After selecting the trigger source, configure the trigger level, hysteresis, bit rate, bus
channel assignment, HF rejection, and other settings.
Trigger Level (Level)
You can set the FlexRay bus signal trigger level for each channel from CH1 to CH4.
Set the trigger level between the levels set for Idle and Data_0 so that the trigger circuit recognizes Data_1 and
Idle as H and Data_0 as L.
• You can set the trigger level in 0.01 division steps to a value that fits within the 8 divisions of the screen. For
example, when the voltage scale is 200 mV/division, you can set the trigger level in 2 mV steps.
• You can reset the trigger level to the current offset voltage by pressing RESET.
