Handover Freq.
Defines the frequency at which the mixer switches from one range to the next (if two
different ranges are selected). The handover frequency can be selected freely within
the overlapping frequency range.
Remote command:
[SENSe:]MIXer:FREQuency:HANDover on page 187
Band
Defines the waveguide band or user-defined band to be used by the mixer.
The start and stop frequencies of the selected band are displayed in the "RF Start" and
"RF Stop" fields.
For a definition of the frequency range for the pre-defined bands, see table 11-2).
The mixer settings for the user-defined band can be selected freely. The frequency
range for the user-defined band is defined via the harmonics configuration (see "Range
1/2" on page 61).
Remote command:
[SENSe:]MIXer:HARMonic:BAND[:VALue] on page 188
RF Overrange
If enabled, the frequency range is not restricted by the band limits ("RF Start" and "RF
Stop"). In this case, the full LO range of the selected harmonics is used.
Remote command:
[SENSe:]MIXer:RFOVerrange[:STATe] on page 191
Preset Band
Restores the presettings for the selected band.
Note: changes to the band and mixer settings are maintained even after using the
PRESET function. This function allows you to restore the original band settings.
Remote command:
[SENSe:]MIXer:HARMonic:BAND:PRESet on page 188
Mixer Type
The R&S FSW option B21 supports the following external mixer types:
"2 Port"
LO and IF data use the same port
"3 Port"
LO and IF data use separate ports
Remote command:
[SENSe:]MIXer:PORTs on page 191
Mixer Settings (Harmonics Configuration)
The harmonics configuration determines the frequency range for user-defined bands
(see "Band" on page 60).
