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
[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..."
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
FREQuency<PhyPt>:CONVersion:ARBitrary:IFRequency
.
Suffix:
<Ch>

Channel number
Parameters:
<FixedFreq>
Fixed stimulus and analyzer frequency
*RST:
1 GHz
Default unit: Hz
