Frequency ← Calibration Frequency RF
Defines the frequency of the internal broadband calibration signal to be used for IF fil-
ter calibration (max. 64
MHz).
For narrowband signals, 64 MHz is sent.
Calibration Frequency MW
Uses the microwave calibration signal as the RF input (for frequencies higher than 8
GHz). This function is used to calibrate the YIG-filter on the microwave converter. The
microwave calibration signal is pulsed.
You can define whether the distance between input pulses is small or wide.

Calibration Analog Baseband
Uses an internal calibration signal as input to the optional Analog Baseband interface.
This signal is only available if the R&S
FSW-B71 option is installed.
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.

Using service functions
The service functions are not necessary for normal measurement operation. Incorrect
use can affect correct operation and/or data integrity of the R&S
FSW.
Therefore, only user accounts with administrator rights can use service functions and
many of the functions can only be used after entering a password. These functions are
described in the instrument service manual.
