EDR Max Input Test
The EDR Maximum input level test case check whether the EUT receiver sensitivity has low
BER performance when tested at a high signal level close to its maximum specified input.
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 -20dBm with no
signal impairments. At each of the test frequencies, the tester transmits packets to the EUT.
The EUT loops back the packets to the tester until the tester has receiver 1,600,000 bits. The
pass criterion is that the EUT BER shall be 1 x 10-3. This pass criterion 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.
