Specifies whether to perform phase tracking, to track carrier frequency changes
during the course of the WLAN burst. The default is OFF, because the 802.11b/g
standards do not appear to call for phase tracking. If this parameter is ON, phase
tracking is performed after all frequency/phase/timing synchronization, and before
any equalization or computation of EVM.

Track Timing
This parameter is available when Radio Std is not 802.11b/g(DSSS/CCK/PBCC).
The Track Timing parameter specifies whether the analyzer tracks timing changes in
the pilot subcarriers. When Track Timing is selected the analyzer applies pilot
subcarrier timing error correction (frequency offset correction) to the pilot and data
subcarriers. This is in addition to Track Amplitude and Track Phase error correction if
selected.
