EDR BER Floor Test
The BER floor performance test checks whether the EUT receiver sensitivity has low residual
BER performance when tested at a level 10dB above its minimum sensitivity. The test
should be performed on the longest supported /4DQPSK and 8DPSK packets with frequency
hopping off.
The signal source level is set so that the EUT receiver has an input level of -60dBm with no
signal impairments. At each of the test frequencies, the tester transmits packets to the EUT.
The EUT loops the packets back to the tester until the tester has receiver 8,000,000 bits.
• If the BER measured is 7 x 10-6 the test has passed and the test stops.
• If the BER is 7 x 10-5 the test continues until the tester has received 160,000,000 bits.
• If the BER measured is 1 x 10-5 the EUT has passed.
This pass criteria applies to each test frequency.
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.
