Power Profile
The power profile display provides a power versus time plot of the transmitter. The display is useful in
assuring that near-far situations will not result in co-channel inter-slot interference on adjacent non-
transmission slots and that the power level will be adequate for acceptable BER performance. The scaling
and position of the vertical power axis can be adjusted to inspect greater range or detail. The horizontal
axis can be changed to view slot 1 or the frame including the additional ramp down time. Display functions
and markers are available for advanced analysis. Overlays of slot centers and burst time regions are shown.
See Figure 2.2.7.7-4.
