Keysight M9421A - Max Result Length; From SIG Symbols

3 WLAN Mode
3.6 Modulation Analysis Measurement
Max Result Length
Specifies a maximum result length.
If the auto-detected length is greater than the specified maximum result length, the
maximum result length is used instead.
The actual results returned will be for a subset of this maximum, as specified by the
Meas Interval and Meas Offset, and will be further limited to the auto-detected
result length if that is shorter than the maximum result length.

From SIG Symbols
For 802.11n/ac/ah/af/ax/be, if From SIG Syms is On:
The Result Length is detected from Signal Field. It compares the decoded length
information to the Max Result Length parameter and uses the smaller value as the
measurement result length.
For 802.11n/ac/ah/af/ax/be, if From SIG Syms Off:
When Result Length is Auto, the analyzer automatically determines the
measurement result length by burst search. It compares the detected result length
to Max Result Length parameter and uses the smaller value as the measurement
result length.
When Result Length is Man, it compares the input result length to the Result Length
parameter and uses the smaller value as the measurement.
