[
SENSe:]CONFigure:MODE:SYSTem:LOSCillator:FREQuency
This command specifies a fixed local oscillator frequency for a new frequency measurement list
in frequency–converting measurement mode. If this value is altered, a new frequency list is
generated.
Parameter
0 Hz to 999.99 GHz
Example
SENS:CONF:MODE:DUT DOWN
The DUT converts the input frequency to a lower output frequency.
SENS:CONF:MODE:SYST:LOSC:FREQ 1MHZ
Specifies the fixed local oscillator frequency for a new list to a value of 1 MHz.
Characteristics
*RST value: – 0 Hz
SCPI: device–specific
Mode
NF
[SENSe:]FREQuency[:CW|:FIXed]
This command specifies a fixed frequency to measure noise and gain continuously (fixed
frequency measurement).
Parameter
<numeric value>
Example
CONF:SING
Configures to run fixed frequency measurements.
FREQ 10MHz
Sets a fixed frequency of 10 MHz.
Characteristics
*RST value: 550 MHz
SCPI: conform
Mode
NF
[SENSe:]FREQuency:LIST:DATA
This command specifies a new frequency list (for frequency list measurement). Each list entry
consists of three separate frequency entities: a receive frequency (RF), a local oscillator
frequency (LO), and an intermediate frequency (IF). The new list completely overwrites all the
current frequency list entries regardless of how many entries are present and how many entries
are being supplied for the new list. The new list is the active list until a new list is automatically
created.
The values specified in this command are not used for a fixed frequency measurement
(CONFigure:SINGle command).
