05 | Keysight | CMMB X-Series Measurement Application N6158A & W6158A - Technical Overview
RF Transmitter Tests
The RF transmitter test requirements for
CMMB transmitter and exciter are efined
in GD/J020-2008 technical specification
and methods of mea-surement for mobile
multimedia broadcasting transmitters
and tech-nical specification and method
of measurement for mobile multimedia
broadcasting exciters (draft) standards.
Table 1 shows RF transmitter and exciter
tests defined by the specs along with the
corresponding measurements provided by
the CMMB measurement application.
