[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOPort<Stg> <SourceType>[,
<SourceNumber>]
Selects an analyzer or an external generator port as a signal source for the LO1 or
LO2 signal.
Note:
If External Switch Matrices are part of the RF connection configuration, operation with
more than one internal source is not supported. In this case only external generators
can be used as local oscillators.
Suffix:
<Ch>
.
Channel number
<Stg> Mixer stage (signals LO 1 or LO 2; see [SENSe<Ch>:
]FREQuency:CONVersion:MIXer:STAGes).
Parameters:
<SourceType> PORT | GENerator | NONE
NONE – LO signal is not controlled by the analyzer.
PORT – analyzer port
GENerator – external generator
*RST: NONE
<SourceNumber> Number of analyzer port or generator.
Example: See [SENSe<Ch>:]FREQuency:CONVersion:MIXer:
MFFixed
Manual operation: See "Port selection" on page 556
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:MFFixed <InputOutput>[,
<FixedFrequency>]
Assigns a fixed frequency to the RF, LO 1, LO 2, or to the IF signal. The fixed fre-
quency setting becomes active if the port is selected as a port with fixed frequency
([SENSe<Ch>:]FREQuency:CONVersion:MIXer:FIXed<Stg>).
Suffix:
<Ch>
.
Channel number
Parameters:
<InputOutput> RF | LO | LO1 | LO2 | IF
Fixed frequency for the specified port
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
Range: Depending on the instrument model [Hz]. The incre-
ment (parameters UP or DOWN) is 0.1 kHz.
