Max Result Length
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.

If From SIG Syms is On:
The Result Length is detected from the High Throughput Signal Field. It compares
the decoded length information to the Max Result Length parameter and uses the
smaller value as the measurement result length.
