OUTPut Subsystem
l
In frequency sweep mode:
l
With TRIGger[1|2]:SOURce IMMediate , the instrument outputs a square wave with a 50% duty cycle (the ris-
ing edge is the sweep trigger) from the Ext Trig connector. Waveform period equals to the sweep time
(SWEep:TIME).
l
With TRIGger[1|2]:SOURce EXTernal , instrument disables the "trigger out" signal. The rear-panel Ext Trig
connector cannot be used for both operations simultaneously (an externally-triggered sweep uses the same
connector to trigger the sweep).
l
With TRIGger[1|2]:SOURce BUS , the instrument outputs a pulse (>1 µs pulse width) from the Ext Trig con-
nector at the beginning of each sweep or burst.
OUTPut:TRIGger:SLOPe {POSitive|NEGative}
OUTPut:TRIGger:SLOPe?
Selects whether the instrument uses the rising edge or falling edge for the "trigger out" signal.
Parameter Typical Return
{POSitive|NEGative}, default POSitive POS or NEG
Set trigger slope to NEGative (falling edge):
OUTP:TRIG:SLOP NEG
l
POSitive outputs a rising edge pulse; NEGative outputs a falling edge pulse.
l
When enabled using OUTPut:TRIGger, a TTL-compatible square wave with the specified edge direction is output
from the rear-panel
Trig Out connector at the beginning of a sweep or burst.
OUTPut:TRIGger:SOURce {CH1|CH2}
OUTPut:TRIGger:SOURce?
Selects the source channel used by trigger output on a two-channel instrument. The source channel determines what
output signal to generate on the trigger out connector.
Parameter Typical Return
{CH1|CH2}, default CH1 CH1 or CH2
Set output trigger source to CH2:
OUTP:TRIG:SOUR CH2
l
In a two-channel instrument, either channel may be source channel for the trigger output.
