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 Protocol Analyzer module has 2GB memory. Recently the 980
Protocol Analyzer module has been enhanced to support 4GB of memory.
