Built in loop back self test in design or on test board for transceivers |
摘要 |
In a method and system for testing a transceiver communication device operating in a test mode, a transmitter output signal generated by a transmitter is adjusted and provided as a loop back to a receiver. The adjustment includes shifting a frequency and attenuating amplitude of the transmitter output signal to substantially match a predefined frequency and a predefined amplitude of a receiver input signal received by the receiver. A pass or fail status of the device is determined by comparing transmitted and received data.
