ABSTRACT:
A multi-port transceiver includes a transmitter and receiver for each port. The invention is a test method and apparatus for testing individual components in the transmit and receive paths. Specifically, the invention includes a method of testing the full range of a programmable gain amplifier (PGA) and an analog to digital converter (ADC) in the receive path of each port. This is accomplished by connecting the transmitter of one port directly to the receiver of a second port, and varying the amplitude of the transmitter over a range of gain settings of the PGA while examining if the dynamic range of the receiver has been exceeded.
