This value also affects the unit conversion (see "Reference Level" on page 396).

High-Pass Filter 1...3 GHz
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.)
Remote command:
INPut:FILTer:HPASs[:STATe] on page 865
YIG-Preselector
Activates or deactivates the YIG-preselector.
An internal YIG-preselector at the input of the R&S FSW ensures that image frequen-
cies are rejected. However, this is only possible for a restricted bandwidth. In order to
use the maximum bandwidth for signal analysis you can deactivate the YIG-preselector
at the input of the R&S FSW, which may lead to image-frequency display.
Note that the YIG-preselector is active only on frequencies greater than 8 GHz. There-
fore, switching the YIG-preselector on or off has no effect if the frequency is below that
value.
Note:
For the following measurements, the YIG-Preselector is off by default (if available).

Input Connector
Determines whether the RF input data is taken from the RF INPUT connector (default)
or the optional BASEBAND INPUT I connector. This setting is only available if the Ana-
log Baseband Interface (R&S FSW-B71) is installed and active for input. It is not avail-
able for the R&S FSW67.
For more information on the Analog Baseband Interface (R&S FSW-B71) see the
R&S FSW I/Q Analyzer and I/Q Input User Manual.
