Triggering Output Changes

The ac source has two independent trigger systems. One is used for generating
output changes, and the other is used for triggering measurements. This section
describes the output trigger system. The measurement trigger system is
described under
The basic components of both systems are the same, but the transient trigger
system has additional delay and phase synchronization features that the
measurement trigger system does not have. The following transient trigger
sources can be selected:
IMMed iate
BUS
EXTernal

SCPI triggering nomenclature

In SCPI terms, trigger systems are called sequences. When more than one trigger
system exists, they are differentiated by naming them SEQuence1, SEQuence2, ...
etc. In the ac source, SEQuence1 is the transient trigger system, SEQuence2 is the
phase synchronization trigger system, and SEQuence3 is the measurement trigger
system.
The ac source uses aliases with more descriptive names for these sequences.
These aliases can be used instead of the sequence forms.
