3 Spectrum Analyzer Mode
3.8 Spurious Emissions Measurement
[:SENSe]:SPURious[:RANGe]:ALL:SWEep:TYPE:AUTO?
Example
:SPUR:ALL:SWE:TYPE:AUTO 1
:SPUR:ALL:SWE:TYPE:AUTO?
Dependencies Available only when Option N9060A-7FP is installed
Preset
ON
State Saved Saved in instrument state
Range Auto | Swept
Annotation When in Auto, and the instrument is in FFT analysis, an indicator, “FFT” is displayed at the right
bottom of range spectrum trace window
Sweep Time Rules
Switches the instrument between NORMal and ACCuracy sweep states.
Setting Auto Sweep Time to Accy (ACCuracy) results in slower sweep times, usually
about three times as long, but yields better amplitude accuracy for CW signals. The
instrument amplitude accuracy specifications only apply when Auto Sweep Time is
set to Accy.
Additional amplitude errors which occur when Auto Sweep Time is set to Norm are
usually well under 0.1 dB, though this is not guaranteed. Because of the faster
sweep times and still low errors, Norm is the preferred setting of Auto Sweep Time.
Auto Sweep Time is set to Norm on a Preset. This means that in the Preset state,
instrument amplitude accuracy specifications do not apply.
Remote Command
[:SENSe]:SPURious:SWEep:TIME:AUTO:RULes NORMal | ACCuracy
[:SENSe]:SPURious:SWEep:TIME:AUTO:RULes?
Example
:SPUR:SWE:TIME:AUTO:RUL ACC
:SPUR:SWE:TIME:AUTO:RUL?
Notes This command is implemented as [:SENSe]:SPURious[:RANGe]
[:LIST]:SWEep:TIME:AUTO:RULes to avoid illegal SCPI node definition, so this command
should be used as [:SENSe]:SPURious:SWEep:TIME:AUTO:RULes
Dependencies Does not appear in SA Mode in VXT
Preset
NORMal
State Saved Saved in instrument state
Range
NORMal|ACCuracy
IF Dithering
Lets you turn IF Dithering on or off. IF Dithering is a technique used in unpreselected
instruments (such as Keysight’s modular instruments) to enhance the rejection of
images and internally-generated spurious signals.
