Triggering Commands

OUTPut:TRIGger:SLOPe {POSitive|NEGative}
OUTPut:TRIGger:SLOPe?
Select a rising or falling edge for the “trigger out” signal. When enabled
using the OUTP:TRIG command (see below), a TTL-compatible square
waveform
with the specified edge is output from the rear-panel
Trig Out
connector
at the beginning of the sweep or burst. Select “POS” to output a
pulse with a rising edge or select “NEG” to output a pulse with a falling
edge. The default is POS. The :SLOP? query returns “POS” or “NEG”.
•When the Immediate (internal) trigger source is selected
(TRIG:SOUR IMM command), the function generator outputs a square
waveform with a 50% duty cycle from the Trig Out connector. The
period of the waveform is
equal to the specified sweep time (
SWE:TIME
command) or burst period
(BURS:INT:PER command) plus 1 ms.
•When the External trigger source is selected (TRIG:SOUR EXT
command), the function generator automatically disables the
“trigger out” signal. The rear-panel 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) trigger source is selected (TRIG:SOUR BUS
command), the function generator outputs a pulse (>1 µs pulse width)
from the Trig Out connector at the beginning of each sweep or burst.
OUTPut:TRIGger {OFF|ON}
OUTPut:TRIGger?
Disable or enable the “trigger out” signal (used for sweep and burst only).
When enabled, a TTL-compatible square waveform with the specified
edge (OUTP:TRIG:SLOP command) is output from the rear-panel
Trig Out connector at the beginning of the sweep or burst. The default
is OFF. The :TRIG? query returns “0” (OFF) or “1” (ON).
