1. It should be noted that masks and clock recovery methods have not been fully defined within the FlexRay physical layer test specification for testing multi-node synchronous

FlexRay systems as of Agilent’s release of the N5402A automotive serial data analysis software option.

2. Oscilloscope sample rate and memory depth have been pre-selected to capture a default cycle time of 3 ms. Instructions are included within each mask file on how to easily

modify the acquisition time to match your synchronous FlexRay system cycle time using a standard text editor.

3. Testing for an observation window of 9.5 µs on 10 Mbps FlexRay signals is in compliance with the physical layer conformance test specification, version 2.1, revision A,

paragraph 5.1.4.6. A 9.5 µs observation window translates into 95 bits for slower baud rate FlexRay systems resulting in observation windows/acquisition times of 19 µs for

5.0 Mbps systems and 38 µs for 2.5 Mbps systems.
