Performing the Capture
p-scope> clean
// clean out extraneous log files.
p-scope> pcap vchk enable
// check video so that the 980 will not initiate a
capture unless video is present.
p-scope> pcap size 4.322
// set capture buffer size to 4.322% (77MB).
Capture buffer size 77MB
Note
: Setting the proper capture buffer is very important and varies per test. The following table will help you
determine what capture buffer setting to use for each test. Please note that the percentages shown in the table to
achieve a required buffer size assume the 980 HDMI Protocol Analyzer module has 2GB memory. Recently the
980 Protocol Analyzer module has been enhanced to support 4GB of memory.
