Level
Activates or deactivates the compensation for level error. If activated, the measure-
ment results are compensated for level error on a per-symbol basis.

Pilots for Tracking (IEEE 802.11n, ac (SISO+MIMO))
In case tracking is used, the used pilot sequence has an effect on the measurement
results.
"According to
standard"
The pilot sequence is determined according to the corresponding
WLAN standard. In case the pilot generation algorithm of the device
under test (DUT) has a problem, the erroneous pilot sequence might
affect the measurement results or the WLAN measurement applica-
tion might not synchronize at all onto the signal generated by the
DUT.
"Detected"
The pilot sequence detected in the WLAN signal to be analyzed is
used by the WLAN measurement application. In case the pilot gener-
ation algorithm of the device under test (DUT) has a problem, the
erroneous pilot sequence will nott affect the measurement results. In
case the pilot sequence generated by the DUT is correct, it is recom-
mended that you use the "According to Standard" setting because it
generates more accurate measurement results.
