Setup for FlexRay Signals
To set up the oscilloscope to capture a FlexRay signal, use the Signals
softkey which appears in the Trigger Menu or the Settings softkey which
appears in the Serial Decode Menu:
1 Press [Trigger]; then, select the FlexRay trigger type.
2 Press Signals to open the FlexRay Signals Menu.
3 Press Source and select the analog channel that is probing the FlexRay
signal.
4 Press Baud and select the baud rate of the FlexRay signal being probed.
5 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.
6 Press Auto Setup to perform the following actions:
• Set the selected source channel’s impedance to 50 Ohms.
• Set the selected source channel’s probe attenuation to 10:1.
• Set the trigger level (on the selected source channel) to - 300 mV.
• Turns on trigger Noise Reject.
• Turns on Serial Decode.
