Basic Digital Operation
Triggering Waveforms
— Segment Ad vance (Dual ARB only) causes a segment in a sequence to
require a trigger to play. The trigger source controls how play moves from
segment to segment (example on page 131 ). A trigger received during the
last segment loops play to the first segment in the sequence. You have two
choices as to how the segments play:
— Single causes a segment in a sequence to play once, then to stop
and wait for a trigger before advancing to the next segment, which
plays to completion. Triggers received during play cause the current
segment to finish, then play advances to the next segment, which
plays to completion.
— Continuous causes a segment in a sequence to play continuously
until the waveform receives another trigger. Triggers received during
play cause the current segment to finish, then play advances to the
next segment, which plays continuously.
— Continuous repeats the waveform until you turn the signal off or select
another waveform, trigger mode, or response. Continuous has the following
options:
— Free Run immediately triggers and plays the waveform; triggers
received during play are ignored.
— Trigger & Run plays the waveform when a trigger is received;
subsequent triggers are ignored.
— Reset & Run (not available in real–time Custom) plays the waveform
when a trigger is received; subsequent triggers restart the waveform.
Accessing Trigger Utilities
The following figures show the menus for the trigger parameters. These figures
show the Dual ARB player, but you can access the trigger utilities through the
Trigger softkey in all ARB formats, and the Pattern Trigger softkey in the Real
Time I/Q Baseband (Custom) format.
— To display the trigger modes, press Mode > Dual ARB > Trigger .
