Patent ID: 7772922

Claim:
A method for testing a data signal amplifier having an output signal power dependent upon a plurality of signal power control parameters, comprising: providing a first control signal corresponding to a first control parameter and having a first one of a first plurality of values; providing a second control signal corresponding to a second control parameter and having a first sequential subset of a second plurality of values; providing, to an amplifier, a power supply voltage and a bias current with at least one of which having a magnitude related to one of said first and second control signals; providing, to said amplifier, an input data signal having a plurality of sequential magnitudes related to another of said first and second control signals; providing, with said amplifier, an output data signal having a plurality of sequential magnitudes related to said one of said first and second control signals and said input data signal; and measuring each one of said plurality of sequential output data signal magnitudes, followed by providing said first control signal corresponding to said first control parameter and having a second one of said first plurality of values, providing said second control signal corresponding to said second control parameter and having a second sequential subset of said second plurality of values, and repeating said providing of said power supply voltage, said bias current, said input data signal and said output data signal, and said measuring of each one of said plurality of sequential output data signal magnitudes.
