Low Energy Tests Running a Script in Standard Mode
7-52 PN: 13000-00205 Rev. N MT8852B Operation Manual
PER Integrity
The MT8852B sends an random even number of BLE reference packets to the EUT at
-30 dBm with a PRBS9 payload. The CRC value for the packets is alternated between a valid
and invalid value. The EUT counts the number of received packets and this value is read by
the MT8852B over the HCI or 2-Wire interface for frame error rate (FER) calculation. The
test is repeated three times at the frequency selected.
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.
Results
1. Position the cursor at "PER Integrity" in the Script menu.
