Physical Layer Measurement Setup Detail

The Right Hand side of the FlexRay Physical Layer tab has the settings for physical layer measurements.

Measurement Parameter Setup

Source – Select the emitting and receiving nodes on the FlexRay

channel where Propagation Delay, Asymmetric Delay and Truncation

are being measured. Jitter is measured on a single channel.

Measurements – Select one of the 4 FlexRay physical layer

measurements. As the boxes are checked the measurement values are

shown.

Probing point – Select the type of line you are probing on:

BP-BM (diff.) if the signal is a differential signal on the communication

channel

RxD-TxD (dig.) if the signal is the two level digital signal of the

communication controller interface

Viewing the Physical Layer Measurements

FlexRay physical layer measurements appear in the Measurement Table just as any other measurements would,

directly under the waveform grid.
