INPut:FILTer:YIG[:STATe] <State>
This command turns the YIG-preselector on and off.
Note the special conditions and restrictions for the YIG filter described in "YIG-Prese-
lector" on page 320.
Parameters:
<State> ON | OFF | 0 | 1
*RST: 1 (0 for I/Q Analyzer, GSM, VSA and MC Group
Delay measurements)
Example:
INP:FILT:YIG OFF
Deactivates the YIG-preselector.
Manual operation: See "YIG-Preselector" on page 320
INPut:IMPedance <Impedance>
This command selects the nominal input impedance of the RF input.
75 Ω should be selected if the 50 Ω input impedance is transformed to a higher impe-
dance using a matching pad of the RAZ type (= 25 Ω in series to the input impedance
of the instrument). The power loss correction value in this case is 1.76 dB = 10 log
(75Ω/50Ω).
Parameters:
<Impedance> 50 | 75
*RST: 50 Ω
Example:
INP:IMP 75
Usage: SCPI confirmed
Manual operation: See "Impedance" on page 319
See "Unit" on page 397
INPut:SELect <Source>
This command selects the signal source for measurements, i.e. it defines which con-
nector is used to input data to the R&S FSW. If no additional options are installed, only
RF input is supported.
