Operating Manual 1145.1084.12 – 30 801
PORT1 ...
Test port number of the analyzer, 1 to 2, 3 or 4, depending on the analyzer
model.
*RST value
PORT1
SCPI, Command
Types
Device-specific, with query.
Example:
CALC4:PAR:SDEF 'Ch4Tr1', 'A1'
Create channel 4 and a trace named Ch4Tr1 to measure the wave quantity a1.
The trace automatically becomes the active trace.
OUTP4:DPOR PORT2
Select drive port 2 for the active trace.
OUTPut[:STATe] <Boolean>
Turns the internal source power at all ports and the power of all external generators immediately on or off.
After the RF power is switched on, the start of the measurement is delayed by approx. 1 s while the
amplifier stages of the analyzer are allowed to settle. To circumvent this delay if you need to turn off the
base channel power for a limited period of time, reduce the base channel power setting or turn off the
drive ports in the Port Configuration dialog instead of using RF Off.
<Boolean>
ON | OFF - Switches the power on or off.
*RST value
ON
SCPI, Command Types
Device-specific, command or query
Example:
OUTP OFF
Turn off the RF source power.
OUTPut:STATe:TYPE FAST | LBNoise
Defines the "RF off Behavior" of the network analyzer.
Parameters
FAST – Only the RF source signal is turned off; the RF amplifiers are still
power supplied.
LBNoise – The power supply of the RF amplifiers is turned off, too (reduced
broadband noise).
*RST value
– (a reset leaves the setting unchanged)

OUTPut:STATe:TYPE FAST
Select the fast RF off mode.
