[SENSe<Ch>:]FREQuency:CONVersion:MIXer:FFIXed <fixed_frequency>
Defines a fixed frequency, to be assigned either to the RF, the LO, or the IF signal
(
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:FIXed RF | LO | IF
).
<Ch> Channel number. If unspecified the numeric suffix is set to 1.
<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:FFIX 1 GHz
Reset the analyzer and specify a fixed frequency of 1 GHz.
FREQ:CONV:MIX:FIX RF
Assign the fixed frequency to the RF signal. The fundamental
frequency is automatically assigned to the LO signal.
FREQ:CONV:MIX:FUND?
Query the assignment of the fundamental frequency to prove
the last statement. The response is
LO
.
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:FIXed RF | LO | IF
Selects the mixer input or output signal which is at the fixed frequency defined via
(
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:FFIXed
).
<Ch> Channel number.
Parameters RF – mixer input signal
LO – local oscillator signal
IF – mixer output signal (mixing product)
*RST value LO
SCPI, Command Types Device-specific, command or query.
Example:
See SENSe<Ch>:]FREQuency:CONVersion:MIXer:FFIXed
[SENSe<Ch>:]FREQuency:CONVersion:MIXer:FUDamental RF | LO | IF
Selects the mixer input or output signal which is at the fundamental frequency (channel frequency, to be
defined by means of
[SENSe<Ch>:]FREQuency:STARt, [SENSe<Ch>:]FREQuency:STOP,
[SENSe<Ch>:]FREQuency:CW
etc.).
<Ch> Channel number.
Parameters RF – mixer input signal
LO – local oscillator signal
IF – mixer output signal (mixing product)
*RST value RF
SCPI, Command Types Device-specific, command or query.
