Keysight M9421A - 3.5.8.3 Advanced; Noise Floor Extension

3 WLAN Mode
3.5 Spurious Emissions Measurement
Example
:RAD:STAN AG
:RAD:STAN?
Notes If the command is sent with unsupported parameters, an error is generated “Settings conflict; option
not installed”
For IQ measurements (CCDF, Power vs Time, Spectral Flatness, IQ Waveform or Modulation Accuracy),
they are also limited by BW Option installed. when any radio standard is selected in an IQ measurement
which maximum BW could not meet this radio standard request, the “Invalid result; Wider BW required”
message will be displayed, and the measurement should return invalid data:
Enum value ACT80 means “AC Two 80MHz” (802.11ac 80+80 MHz)
Enum value AXT80 means “AX Two 80MHz” (802.11ax 80+80 MHz)

Noise Floor Extension
Allows you to turn on/configure the Noise Floor Extension (NFE) function. Some
Modes (such as Spectrum Analyzer), support two states of NFE, Full and Adaptive.
The ON state (in Modes that do not support Adaptive NFE) matches the FULL state
(in Modes that do support Adaptive NFE).
In ON or FULL NFE, the expected noise power of the instrument (derived from a
factory calibration) is subtracted from the trace data. This will usually reduce the
apparent noise level by about 10 dB in low band, and 8 dB in high band (>~3.6 GHz).
In Adaptive NFE, there is not the same dramatic visual impact on the noise floor as
there is in Full NFE. Adaptive NFE controls the amount of correction that is applied
based on other instrument settings like RBW, averaging and sweep time. Adaptive
NFE controls the degree of potential improvement in the noise floor to give more
improvement for those instrument settings that can make good use of the potential
improvement, such as settings that provide more averaging. The result is that when
not much averaging is being performed, the signal displays more like the NFE-off
