Example:
See SENSe<Ch>:]FREQuency:CONVersion:MIXer:FFIXed
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:IFFixed <fixed_frequency>
Defines a fixed frequency and assigns it to the IF signal (for alternative commands see example below).
<Ch> Channel number.
<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:IFF 1 GHz
Reset the analyzer and specify a fixed frequency of 1 GHz, to
be assigned to the IF signal.
FREQ:CONV:MIX:FFIX?; FIX?
Query the fixed frequency and the signal assignment using the
alternative commands. The response is
1000000000;IF
.
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOEXternal NONE |
<port_number> | SOURce1 | SOURce2
Selects an external generator as a signal source for the LO signal (external source; to select an internal
source use
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOINternal
).
<Ch> Channel number.
NONE LO signal is not controlled by the analyzer.
<port_number> Number of external generator as defined in the System
Configuration – External Generators dialog.
*RST value NONE
SCPI, Command
Types Device-specific, command or query.
Example:
FREQ:CONV:MIX:LOEX 1
Select the generator no. 1 as a signal source for the LO signal. An
error message -222,"Data out of range..." is generated unless an
external generator is available.
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:LOFixed <fixed_frequency>
Defines a fixed frequency and assigns it to the LO signal (for alternative commands see example
below).
<Ch> Channel number.
