Abstract:
1. In a transceiver having a plurality of ports with each port including a transmitter with a variable amplitude and a receiver having a programmable gain amplifier (PGA) and an analog to digital converter (ADC), a method for testing the components of the transceiver, comprising: (1) coupling a transmitter of a first port to a receiver of a second port, wherein an amplitude of the transmitter of the first port is set to a maximum amplitude and a gain of the PGA of the receiver of the second port is set to a minimum gain; (2) transmitting a signal from the transmitter of the first port to the receiver of the second port; and (3) varying the amplitude of the transmitter of the first port over a range of amplitude settings and detecting if the signal transmitted by the transmitter of the first port has been received by the receiver of the second port without error over the range of amplitude settings of the transmitter of the first port.
