Puncture Pattern
Indicates which 20M is punctured:
–
1110 for 11be/ax 80M: the last 20M is punctured
–
11110011 for 11be/ax 160M: the fifth and sixth 20M are punctured

Noise Floor Extension
Allows you to turn on/configure the Noise Floor Extension (NFE) function. Some
Modes (such as Spectrum Analyzer Mode), 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 usually reduces 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
