<fixed_frequency> Fixed frequency.
Range [def. unit] Depending on the instrument model [Hz]. The increment
(parameters UP or DOWN) is 0.1 kHz.
*RST value Minimum of the analyzer's frequency range, f
MIN
SCPI, Command
Types
Device-specific, command or query.
Example:
*RST; FREQ:CONV:MIX:LOF 1 GHz
Reset the analyzer and specify a fixed frequency of 1 GHz, to
be assigned to the LO signal.
FREQ:CONV:MIX:FFIX?; FIX?
Query the fixed frequency and the signal assignment using the
alternative commands. The response is
1000000000;LO
.
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOINternal NONE |
<port_number>
Selects an analyzer port as a signal source for the LO signal (internal source; to select an external
generator use
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOEXternal
).
<Ch> Channel number.
NONE LO signal is not controlled by the analyzer.
<port_number> Analyzer port number
Range [def. unit] 3 (for 3-port analyzers), 3, 4 (for 4-port analyzers)

Example:
FREQ:CONV:MIX:LOIN 3
Select port no. 3 as a signal source for the LO signal.
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:RFFixed <fixed_frequency>
Defines a fixed frequency and assigns it to the RF signal (for alternative commands see example
below).
<Ch> Channel number.
