MT8850A / MT8852A Bluetooth Test Set Specification
Carrier Frequency Drift
MT8850A/MT8852A measures carrier frequency drift according to the Bluetooth RF Test
Specification. Measurement of frequency drift is made with the EUT in test mode, with
either loopback or transmitter test mode enabled. EUT transmits longest supported
packets, with a 10101010 payload to the EUT. Measurements are made with hopping off
and then with hopping on. Frequency drift is measured at three defined frequencies with
hopping off and every frequency with hopping on.
Link conditions:
Hopping: OFF or ON – measure at Defined, All, or Any frequencies
Test mode: ON
Loopback or TX mode
Payload: 10101010
Packet type: DH1, DH3, DH5
Measurement:
Supported measurements: Carrier frequency drift
Number of measurement channels: User selectable, Defined (3), All, or Any
RF input measurement range: +20 dBm to -35 dBm
Frequency drift measurement range: 0 Hz to 200 kHz, and > 2000/50µs
Frequency resolution: 1 kHz
Accuracy: 1 kHz
