Specification MT8850A / MT8852A Bluetooth Test Set
13000-000109 C-5
June 2003
Initial Carrier Frequency Tolerance
MT8850A/MT8852A measures initial carrier frequency tolerance according to the
Bluetooth RF Test specification.
Measurement of initial carrier frequency is made with the EUT in test mode, TX mode and
hopping on and/or off. MT8850A/MT8852A transmits DH1 packets, with a PRBS 9
payload. Initial carrier frequency is measured at three defined frequencies.
MT8850A/MT8852A identifies the position of p0 and measures the average frequency of
the 4 preamble bits.
