Generation 2 Single Channel BR Station Verification Procedures
6. The resulting output will look similar to this:
NOTE
RX Path1 RSSI must read -80dBm ± 1dBm for the BER
Floor verification to be accurate. Adjust the output
level of the R2660 to compensate for loss in the test
cables and three-way splitter.
BER Floor Measurement: Generation 2 Base Radio
1. Verify that the R2660 is set to 810MHz and is producing a power level of
-80dBm. (See “Receiver Verification Procedure: Generation 2 Base Radio” on
page 23.)
2. Using the MMI commands below, issue the command to put the BR into
single branch mode. If the resulting bit error rate for receiver branches 1, 2,
and 3 is less than 0.01%, the receiver has passed the test.
