EDR Sensitivity Test
The sensitivity test checks the EUT receiver sensitivity performance in terms of bit error rate
using a non-ideal (dirty) test signal. 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 -70dBm with
defined 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 1,600,000
bits.
• If the BER measured is 7 x 10-5 the test has passed and the test stops.
• If the BER is 7 x 10-5 the test continues until the tester has received 16,000,000 bits.
• If the BER measured is 1 x 10-4 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.
