Running a Script in Standard Mode Enhanced Data Rate Tests
MT8852B Operation Manual PN: 13000-00205 Rev. N 7-33
EDR Differential Phase Test
In this test the EUT transmits a packet with a defined PRBS9 payload. The payload of the
received packet is demodulated and compared with the defined ideal packet to give a
resultant symbol error rate. The Bluetooth 2.0 specification stipulates that zero errors be
detected in 99% of 100 packets transmitted. The specification requires this test to be
performed only on 2-DH1 and 3-DH1 packets on channel 0.
The table below details the test conditions and the associated default settings. Permitted
variations from the default setting are detailed in the “User Range” column.
