Patent ID: 7299166

Claim:
A method for characterizing a frequency translation device, the method comprising: supplying a stimulus condition as input to the frequency translation device to generate an output spectrum; measuring a plurality of intermodulation products in the output spectrum of the frequency translation device resulting from the stimulus condition input, the plurality of intermodulation products further comprising a plurality of sum intermodulation products and a plurality of difference intermodulation products; establishing a predetermined file format; storing the plurality of sum intermodulation products and the plurality of difference intermodulation products in a plurality of output files according to the predetermined file format; assigning a variable to identify the intermodulation products stored in each of the plurality of output files as a sum intermodulation product or a difference intermodulation product; and establishing an index file to identify the stored output files, wherein the index file comprises at least one variable associated with the stimulus condition that identifies the stored output files associated with the stimulus condition.
