To create a playback file through the command line:

1. From the pscope prompt in the 980 GUI Manager Console, enter the following command to set the capture

mode. In this case you will be using the tmds mode which captures all raw TMDS characters.

Note

: You enter commands in the

Command

field near the top of the Console panel.

#p-scope>pcap mode tmds

2. From the pscope prompt enter the command to set the capture buffer size in percent. Typically 20 to 40

percent is plenty large enough.

#p-scope>pcap size 20

3. From the pscope prompt enter the command to start the capture.

#p-scope>pcap start
