TRIGger:EXTernal<2...2>:IMPedance <impedance>
Effective only if
TRIGger:SOURce EXTernal2
is set.
Sets termination resistance of the second external trigger input. Choose the setting
that fits the impedance of the trigger source to minimize reflections on the trigger sig-
nals.
Suffix:
<2...2>

Parameters:

*RST: HIGH
TRIGger:HOLDoff <holdoff>
Sets the hold-off time, see Chapter 8.5.2.5, "Hold-off time" , on page 45.
Parameters:
<holdoff> Range: 0.00 to 10.00
*RST: 0.00
Default unit: Seconds
TRIGger:HYSTeresis <hysteresis>
Sets the hysteresis. A trigger event occurs, if the trigger level:
●
Falls below the set value on a rising slope.
●
Rises above the set value on a falling slope
Thus, you can use this setting to eliminate the effects of noise in the signal for the edge
detector of the trigger system.
Parameters:
<hysteresis> Range: 0.00 to 10.00
*RST: 0.00
Default unit: DB
TRIGger:IMMediate
Causes a generic trigger event. The power sensor leaves the waiting for trigger state
immediately, irrespective of the trigger source and the trigger delay, and starts the
measurement.
This command is the only way to start a measurement if the trigger source is set to
hold,
TRIGger:SOURce HOLD
. Only one measurement cycle is executed, irrespective
of the averaging factor.
