[ DownConverter Fixed LO Frequency]
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:FREQuency
Function description:
This command is used to set/query the downconverter fixed LO frequency.
Setting format:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:FREQuency <freq>
Query format:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:FREQuency?
Return value:
The unit is Hz
Parameter description:
The input frequency units include Hz, kHz, MHz, GHz or k, M, G. It is Hz by
default.
<freq> Fixed LO frequency.
Range:[1Hz, 300GHz]
Example:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:FREQuency 3GHz

[ DownConverter LO Frequency Offset ]
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:OFFSet
Function description:
This command is used to set/query the local oscillator frequency offset in the
downconverter mode.
Setting format:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:OFFSet DSB|LSB|USB
Query format:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:OFFSet?
Return value:
DSB|LSB|USB
Parameter description:
LSB: Lower sideband (signal frequency < LO frequency)
USB: Upper sideband (signal frequency > LO frequency)
DSB: Double sideband (no frequency offset)
Example:
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:OFFSet DSB
:SENSe:CONFigure:MODE:DOWNconv:LOSCillator:OFFSet?
Reset status:
lower sideband
