NOTE
As the occurrence possibility of specified FlaxRay frame is very low, it is recommended that you
set the oscilloscope to "Normal" trigger mode when the trigger condition is set to "Frame", so
as to prevent the instrument from triggering automatically while waiting for the specified
frame. The same goes for "Error" trigger condition. In addition, when multiple FlexRay errors
occur at the same time, you need to adjust the trigger holdoff so as to view the specific error.
