INPut:FILTer:HPASs[:STATe]
<State>
Activates an additional internal high-pass filter for RF input signals from 1
GHz to
3
GHz. This filter is used to remove the harmonics of the R&S
FSW in order to mea-
sure the harmonics for a DUT, for example.
This function requires option R&S
FSW-B13.
(Note: for RF input signals outside the specified range, the high-pass filter has no
effect. For signals with a frequency of approximately 4 GHz upwards, the harmonics
are suppressed sufficiently by the YIG filter.)
Parameters:
<State>
ON | OFF
*RST:
OFF
Usage:
SCPI confirmed
Manual operation:
See
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
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
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
(75
Ω
/50
Ω
).
The command is not available for measurements with the Digital Baseband Interface
(R&S
FSW-B17).
Parameters:
<Impedance>
50 | 75
*RST:
50 Ω
