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 function
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 sweep time.
•When the External trigger source is selected, the function 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 function generator
outputs a pulse (>1 µs pulse width) from the Trig Out connector at the
beginning of each sweep or burst.
• Front-Panel Operation: After enabling sweeps, press the
Trigger 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}
