Sidelobe power spectral density (PSD)
across 1MHz shall be attenuated below
the TX (PSD) power (P) by 43+10log
(P)
Spectral Mask must be measured at
the output of the channel filter.
TX input has to exceed FCC spectral
mask definition if OEM exciter is used.
For TX compliance shoulder level
typically should be better than 50dB at
breakpoint w/ minimum of 8db non-
linear correction capability.
