SOURce<Ch>:FREQuency:CONVersion:MIXer:PMODe <arg0>[, <arg1>]
Sets the RF, LO 1, LO 2, or the IF signal ports to fixed power or to the channel base
power.
Suffix:
<Ch>
.
Channel number
Parameters:
<arg0> RF | LO | LO1 | LO2 | IF
RF – mixer input signal
LO | LO1 – local oscillator signal no. 1
LO2 – local oscillator signal no. 2, for 2-stage mixer measure-
ments ([SENSe<Ch>:]FREQuency:CONVersion:MIXer:
STAGes)
IF – mixer output signal
<arg1> FUNDamental | FIXed
FIXed – use a fixed power, to be specified via SOURce<Ch>:
FREQuency:CONVersion:MIXer:PMFixed
FUNDamental – use the channel base power specified via
SOURce<Ch>:POWer<Pt>:STARt, SOURce<Ch>:
POWer<Pt>:STOP,
SOURce<Ch>:POWer<Pt>[:LEVel][:IMMediate][:
AMPlitude]
*RST: Minimum of the analyzer's frequency range

Manual operation: See "RF, IF and Mixer Stages" on page 365
SOURce<Ch>:FREQuency<PhyPt>[:CW] <FixedFreq>
SOURce<Ch>:FREQuency<PhyPt>: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
SOURce<Ch>:FREQuency<PhyPt>:CW and
SOURce<Ch>:FREQuency<PhyPt>:FIXed are equivalent.
The frequency range depends on the R&S ZNA model; see Table 7-17.
Note:SOURce<Ch>:FREQuency<PhyPt>[:CW]|:FIXed is equivalent to
[SENSe<Ch>:]FREQuency[:CW]|:FIXed. Source and receiver frequency are
always equal; the four commands overwrite each other.
With option R&S ZNA-K4, Frequency Conversion Measurements, port-specific source
and receiver frequencies can be defined; see SOURce<Ch>:FREQuency<PhyPt>:
CONVersion:ARBitrary:IFRequency.
