Specification MT8850A / MT8852A Bluetooth Test Set
13000-000109 C-7
January 2003
Sensitivity - Single Slot Packets
MT8850A/MT8852A measures single slot sensitivity according to the Bluetooth RF Test
Specification
BER and FER are measured with the EUT in test mode and loopback on.
MT8850A/MT8852A transmits DH1 packets, with a PRBS 9 payload to the EUT. The user
can select to run the measurement with hopping on or off. Dirty transmitter conditions as
defined in the Bluetooth test specifications can be enabled.
Link conditions:
Hopping: OFF or ON, user selectable
Test mode: ON
Loopback: ON
Payload: PRBS 9
Packet type: DH1
Dirty transmitter (as defined in RF test spec): ON or OFF, user selectable
Measurement:
Supported measurements: BER, total number of bit errors and FER
Number of measurement frequencies: Three with hopping off, or hopping on.
Number of measured bits: 1 to 32,768 packets (216 to 7,077,888 bits)
MT8850A/MT8852A transmitter output range: 0 dBm to -80 dBm, resolution 0.1
dB
BER/FER measurement range: 0.000% to 100%
BER/FER resolution: 0.001%
Dirty transmitter specification
MT8850A/MT8852A transmits the first 20 ms with the first set of measurement conditions,
the second 20 ms with the second set of measurement conditions up to the tenth set of
conditions. The cycle is then repeated until the test is complete.

In addition to the above measurement conditions, MT8850A/MT8852A transmits with a
sine wave, frequency modulation, with a deviation of ±25 kHz. rate 1.6 kHz, synchronized
to zero phase at the packet start.
