Handover Freq
If due to the LO frequency the conversion of the input signal is not possible using one
harmonic, the band must be split. An adjacent, partially overlapping frequency range
can be defined using different harmonics. In this case, the sweep begins using the har-
monic defined for the first range. At the specified "handover frequency" in the overlap-
ping range, it switches to the harmonic for the second range.
The handover frequency can be selected freely within the overlapping frequency
range.
Remote command:
[SENSe:]MIXer<x>:FREQuency:HANDover
Band
Defines the waveguide frequency band or user-defined frequency 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
.
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
Remote command:
[SENSe:]MIXer<x>:HARMonic:BAND
RF Overrange
Sometimes, the harmonics defined for a specific band allow for an even larger fre-
quency range than the band requires. By default, the pre-defined range is used. How-
ever, you can take advantage of the extended frequency range by overriding the
defined "RF Start" and "RF Stop" frequencies by the maximum values.
If "RF Overrange" is enabled, the frequency range is not restricted by the band limits
("RF Start" and "RF Stop"). In this case, the full frequency range that can be reached
using the selected harmonics is used.
Remote command:
[SENSe:]MIXer<x>:RFOVerrange[:STATe]
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<x>:HARMonic:BAND:PRESet
Mixer Type
The External Mixer option 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
