Patent ID: 7251574

Claim:
A method for testing bit error rate (BER) performance of transceivers that phase encode digital data when transmitting the digital data, the method comprising: running a normal test on a reference transceiver using normal phase encode operations, the normal test collects normal bit error rate (BER N ) values; selecting a phase offset for use in phase encoding of digital data in the reference transceiver to elevate the bit error rate of the reference transceiver; running an elevated test on the reference transceiver using the phase offset in phase encoding of the digital data, the elevated test collects elevated bit error rate (BER E ) values; building a mapping function to map from BER E values to BER N values; and running a production test on transceiver production units using the elevated test to accelerate the bit error rate test, and using the map function to map the BER E values of each production transceiver to BER N values so that the BER N values of the production transceiver may be compared to the bit error rate performance specification for the transceiver.
