MT8850A / MT8852A Bluetooth Test Set

13000-000109

C-5

 January 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.

Link conditions:

Hopping: OFF or ON – measure at Defined, All, or Any frequencies

Test mode: ON

Loopback or TX mode

Payload: PRBS 9

Packet type: DH1

Measurement:

Supported measurements: Initial carrier frequency error

Number of measurement channels: User selectable, Defined (3), All, or Any

RF input measurement range: +20 dBm to -35 dBm

Initial frequency error measurement range: 0 Hz to ±150 kHz

Frequency resolution: 1 kHz

Accuracy: 1 kHz

Speed: Greater then 300 DH1 packets/sec. with hopping mode set to “Any”.
