Auto MCACC selected at Advanced MCACC or with ALL
or Full Band Phase Ctrl selected when Auto MCACC is
selected, the graph before group delay calibration is also
displayed.
When After is selected at Calibration, the group delay
after calibration is displayed. Compared to when Before
is selected, with After there is less difference in the delay
between frequency bands and the group delay between
the different channels is uniform, allowing you to check
the full band phase control effect.
No Data is displayed if the selected group delay has not
been measured.
