4.2.15 Linear Precorrection
(Group Delay & Amplitude
Response)
4.2.15.1 Objective
To verify the linear precorrection - group delay and amplitude response compensation -
at the output of the band pass filter.
The transmitter will be operated in digital mode (FLO modulation) at the rated output
power at the MediaFLO channel frequency. The transmitter output will be connected to
the MediaFLO channel filter assembly terminated in a dummy load.
NOTE:
The transmitter RF must be turned ON at the rated RF output power for at least
four (4) hours to allow for the filter to warm up.
4.2.15.2 Requirements
Group Delay < 1usec
