Trigger Out Signal
A “trigger out” signal is provided on the rear-panel Trig Out connector
(used with sweep and burst only). When enabled, a TTL-compatible
square waveform
with either a rising edge (default) or falling edge is
output from the
Trig Out
connector
at the beginning of the sweep.
• When the Internal (immediate) trigger source is selected, the
waveform generator outputs a square waveform with a 50% duty
cycle from the Trig Out connector at the beginning of the sweep. The
frequency of the waveform is equal to the specified total sweep time.
• When the External trigger source is selected, the waveform generator
automatically disables the “trigger out” signal. The
Trig Out
connector
cannot be used for both operations at the same time (an externally-
triggered waveform uses the same connector to trigger the sweep).
• When the Manual trigger source is selected, the waveform generator
outputs a pulse (>1 µs pulse width) from the Trig Out connector at the
beginning of each sweep or burst.
• To specify whether the waveform generator triggers on the rising or
falling edge of the Ext Trig connector, press
, then
the Trig Out
Setup softkey. Then select the desired edge by pressing the Trig Out
softkey.
• Remote Interface Operation:
OUTPut:TRIGger:SLOPe {POSitive|NEGative}
OUTPut:TRIGger {OFF|ON}
