24 FlexRay Triggering and Serial Decode
6 Press Source and select the analog channel that is probing the FlexRay signal.
7 Press Threshold; then, turn the Entry knob to set the threshold voltage level.
The threshold level should be set below the idle level.
The threshold voltage level is used in decoding and will become the trigger
level when the trigger type is set to the selected serial decode bus.
8 Press Baud and select the baud rate of the FlexRay signal being probed.
9 Press Bus and select the bus type of the FlexRay signal being probed.
It is important to specify the correct bus because this setting affects CRC error
detection.
10 Press Auto Setup to perform the following actions:
• Sets the selected source channel's impedance to 50 Ohms, assuming a
differential active probe that requires a 50 ohm termination is being used .
• Sets the selected source channel's probe attenuation to 10:1.
• Sets the trigger level (on the selected source channel) to -300 mV.
• Turns on trigger Noise Reject.
• Turns on Serial Decode.
• Sets the trigger type to FlexRay.
FlexRay Triggering
To set up the oscilloscope to capture a FlexRay signal, see "Setup for FlexRay
Signals" on page 361.
After you have set up the oscilloscope to capture a FlexRay signal, you can then
set up triggers on frames (see page 363), errors (see page 364), or events (see
page 364).
To display FlexRay serial decode, see "FlexRay Serial Decode" on page 365.
