Use the Comm Trigger control window to trigger the instrument in conjunction with mask testing on
commun
ications codes and standards. The c ontrols work together to define the parameters for the trigger
event. The standards that appear in the Standard drop-down list depend on the coding format that you
selected. The coding format also determines whether upper, lower, single, or clock threshold levels or
pulse forms are used. The standard determines the bit rate. When you click on the trigger window controls,
the trigger graphic
(see page 386) shows the trigger sequence.
