Frequency Sweep Commands
4
TRIGger:SLOPe {POSitive|NEGative}
TRIGger:SLOPe?
Select whether the function generator uses the rising edge or falling
edge of the trigger signal on the rear-panel Trig In connector for an
externally-triggered sweep. The default is POS (rising edge).
The :SLOP? query returns “POS” or “NEG”.
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. 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 (the rising edge is the sweep trigger)
from the Trig Out connector. The period of the waveform is equal to
the specified sweep time (SWE:TIME command).
•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
sweep uses the same connector to trigger the sweep).
•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.
OUTPut:TRIGger {OFF|ON}
OUTPut:TRIGger?
Disable or enable the “trigger out” signal. 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. The default is OFF. The :TRIG? query returns
“0” (OFF) or “1” (ON).
