RF Transmitter Tests
The RF transmitter test requirements
for DTMB transmitter and exciter are
defined in GY/T 229.4 2008 and GY/T
229.2 2008 standards. Table 1 shows
RF transmitter and exciter tests
defined by the specification along
with the corresponding measure-
ments provided by the DTMB (CTTB)
measurement application.
