Trigger Output 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 rear-panel
Trig Out
connector
at the beginning of the
sweep or burst.
•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 or burst.
The period of the waveform is equal to the specified sweep time or
burst period.
•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
or burst).
•When the Bus (software) or 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 or burst, 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}
