*RST: HIGH
TRIGger:HOLDoff <holdoff>
Sets the hold-off time, see Chapter 8.5.2.5, "Hold-Off Time" , on page 52 .
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.
Usage: Event
TRIGger:LEVel <level>
Effective only if
TRIGger:SOURce INTernal
.
Sets the trigger threshold for internal triggering derived from the test signal.
If you enter a value without unit, the unit is defined by
TRIGger:LEVel:UNIT
.
If an S-parameter device is active and/or if a mounted component with a global offset
in front of the sensor is considered, the currently effective trigger threshold and a trig-
ger threshold to be input are referenced to the appropriately shifted sensor data. If the
S-parameter device and/or the offset correction are disabled, the trigger threshold and
its input limits are adjusted as necessary.
