A system and method for testing communication performance between two wireless communication devices. A value table is used to determine a test string in both the unit under test and another wireless device. An initiating device transmits data to the secondary device, which may check the incoming data for errors against an “expected” data string. The secondary device may then correct the incoming data (if necessary) and transmit it back to the initiating device. The initiating device may check this data and combine it with data from the secondary device in order to determine an overall bit error rate (BER) and/or packet error rate (PER).
