3 Spectrum Analyzer Mode
3.9 SEM Measurement
3.9.1 Results for n = 1
For WLAN Mode, these results apply to all standards except 802.11ac/ax
(80+80MHz).
Returns 82 comma-separated scalar results, in the following order:
k is an index for each offset: k = 0 for offset A; k = 1 for offset B; k = 2 for offset C, etc.
The number of offsets is 6 (A-F).
