[SENSe<Ch>:]FREQuency:CONVersion:MIXer:TFRequency<Stg>
<IFConversionMode>
Selects the frequency conversion mode of the IF signal.
Suffix:
<Ch>
.
Channel number.
<Stg> Mixer stage (1 or 2; see [SENSe<Ch>:]FREQuency:
CONVersion:MIXer:STAGes.
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 "RF, IF and Mixer Stages" on page 365
[SENSe<Ch>:]FREQuency:IMODulation:CONVersion <OFF>
Disables the intermodulation measurement and switches back to normal mode (no fre-
quency conversion).
Suffix:
<Ch>
.
Channel number
Setting parameters:
<OFF> OFF
Disable intermodulation measurement
*RST: n/a
Example: See [SENSe<Ch>:]FREQuency:IMODulation:LTONe
