Parameters:
<IFConversionMode> DCUPper | DCLower | UCONversion | BAND1 | BAND2
DCUPper | BAND2 – IF = RF - LO (down conversion upper side-
band, equivalent to BAND2)
DCLower | BAND1– IF = LO - RF (down conversion lower side-
band, equivalent to BAND1)
UCONversion – IF = LO + RF (up conversion)
*RST: DCUPper
Example:
*RST; FREQ:CONV:MIX:LOF 3 GHz
Reset the analyzer and specify a fixed frequency of 1 GHz, to be
assigned to the LO signal.
FREQ:STAR 1 GHz; STOP 2 GHz
Define a sweep range between 3 and 4 GHz, to be assigned to
the RF signal.
FREQ:CONV:MIX:TFR DCL
Select down conversion to the lower sideband, corresponding to
an IF frequency range between 2 GHz and 1 GHz.
Manual operation: See "Conversion" on page 601
[SENSe<Ch>:]FREQuency[:CW] <FixedFreq>
[SENSe<Ch>:]FREQuency:FIXed <FixedFreq>
Defines the fixed (Continuous Wave, CW) frequency for all sweep types operating at
fixed frequency ("Power", "Time", "CW Mode"). The two command forms
[SENSe<Ch>:]FREQuency[:CW] and [SENSe<Ch>:]FREQuency:FIXed are
equivalent.
This command also defines the center frequency of the intermodulation spectrum dia-
gram (option R&S ZNB/ZNBT-K14). The frequency range depends on the R&S ZNB/
ZNBT model; see Chapter 7.3.14.9, "[SENSe:]FREQuency...", on page 1267.
Note:[SENSe<Ch>:]FREQuency[:CW]|:FIXed is equivalent to
SOURce<Ch>:FREQuency<PhyPt>[:CW]|:FIXed. Source and receiver frequency
are always equal; the four commands overwrite each other.
With option R&S ZNB/ZNBT-K4, Frequency Conversion Measurements, port-specific
source and receiver frequencies can be defined; see SOURce<Ch>:
FREQuency<PhyPt>:CONVersion:ARBitrary:IFRequency.
Suffix:

Channel number
Parameters:
<FixedFreq> Fixed stimulus and analyzer frequency
