Enhanced Data Rate Tests Configuring Tests in Standard Mode
10-26 PN: 13000-00110 Rev. V MT8852B Programming Manual
Differential Phase Encoding Test Configuration (EDPCFG)
(MT8852B and MT8852B-042 only)
In this measurement 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
are detected in 99% of 100 packets transmitted.
The Bluetooth test specification only requires this test to be performed on 2-DH1 and 3-DH1
packets on channel 0.
