Group and Alternate Signals

To validate multiple signals, you will need to capture data from the selected channels and save them for careful offline analysis.

Here, two channels from a set of 12 connected channels - input pipe channels IP0 and IP1 - are selected for logging to a disk file.

You would follow the steps from the one-channel example , but select two channels instead of just one. Then, use a Disklog window to specify the file for saving the data.
