Test data generating feature is to be used for the packet jitter measure-
ments. The analyzer supports generating the test data flow in two following
modes:
•
test data is generated and then jitter is measured at the same port (see
fig. 5.87);
•
test data is generated at one port, and then jitter is measured at another
one (see fig. 5.88); in this case, destination port could be a port at a
remote device (see fig. 5.89).
When generating the test data has been started, all settings in the menu
become inaccessible for editing.
