User Manual 1173.9411.02 ─ 19
Note that this command can be used for
any trigger source
, not just IF Power
(despite the legacy keyword).
Note:
If you perform gated measurements in combination with the IF Power trigger, the
R&S
FSW ignores the holding time for frequency sweep, FFT sweep, zero span and
I/Q data measurements.
Parameters:
<Period>
Range:
0 s to 10 s
*RST:
0 s
Example:
TRIG:SOUR EXT
Sets an external trigger source.
TRIG:IFP:HOLD 200 ns
Sets the holding time to 200 ns.
Manual operation:
See
TRIGger[:SEQuence]:IFPower:HYSTeresis
<Hysteresis>
This command defines the trigger hysteresis, which is only available for "IF Power" trig-
ger sources.
Parameters:
<Hysteresis>
Range:
3 dB to 50 dB
*RST:
3 dB
Example:
TRIG:SOUR IFP
Sets the IF power trigger source.
TRIG:IFP:HYST 10DB
Sets the hysteresis limit value.
Manual operation:
See
TRIGger[:SEQuence]:LEVel[:EXTernal<port>]
<TriggerLevel>
This command defines the level the external signal must exceed to cause a trigger
event.
Note that the variable INPUT/OUTPUT connectors (ports 2+3) must be set for use as
input using the
Suffix:
<port>
.
Selects the trigger port.
1 = trigger port 1 (TRIGGER INPUT connector on front panel)
2 = trigger port 2 (TRIGGER INPUT/OUTPUT connector on front
panel)
3 = trigger port 3 (TRIGGER3 INPUT/OUTPUT connector on
rear panel)
Parameters:
<TriggerLevel>
Range:
0.5 V to 3.5 V
*RST:
1.4 V
