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.
Parameters:
<level> Range: 1.0e-7 to 200.0e-3
*RST: 1.0e-6
Default unit: Watts
Manual operation: See "Trigger Level" on page 52
TRIGger:LEVel:UNIT <unit>
Sets the unit of the trigger level if this value is entered without a unit.
See also
TRIGger:LEVel
on page 81.
Parameters:
<unit> DBM | W | DBUV
*RST:
W
Manual operation: See "Trigger Level" on page 52
TRIGger:MASTer:PORT <master_port>
Selects the port where the sensor outputs its own trigger event in case it is trigger mas-
ter. See
TRIGger:MASTer:STATe
for more information.
If the sensor is the trigger master, it can output its trigger event either on the
EXTernal<1>
or
EXTernal2
.
