form using the multipurpose knobs.
Behavior. Use the Comm Trigger control window to trigger the instrument in conjunction with mask testing on communications
codes and standards. The controls 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 shows the trigger sequence.
