Abstract

A method and apparatus for testing multiple data signal transceivers substantially simultaneously with a common transceiver tester by analyzing previously captured data signal transmissions from some of the data signal transceivers while continuing to capture further data signal transmissions from additional ones of the data signal transceivers.

9. The method of claim 1 , wherein said capturing comprises:

separating said plurality of data signal transmissions to provide a plurality of data signals each of which corresponds to said respective portion of said plurality of data signal transmissions from said each one of one or more respective ones of said plurality of data signal transceivers;

digitizing each one of said plurality of data signals to provide a plurality of digitized data sets; and

storing said plurality of digitized data sets to provide said one or more corresponding portions of a plurality of captured data.

10. The method of claim 1 , wherein said capturing comprises:

receiving said respective portion of said plurality of data signal transmissions from said each one of one or more respective ones of said plurality of data signal transceivers;

digitizing each said received respective portion of said plurality of data signal transmissions to provide a plurality of digitized data;

separating said plurality of digitized data to provide a plurality of digitized data sets; and

storing said plurality of digitized data sets to provide said one or more corresponding portions of a plurality of captured data.

11. The method of claim 1 , wherein said capturing comprises:

receiving said respective portion of said plurality of data signal transmissions from said each one of one or more respective ones of said plurality of data signal transceivers;

digitizing each said received respective portion of said plurality of data signal transmissions to provide a plurality of digitized data;

storing said plurality of digitized data to provide a stored plurality of digitized data; and

separating said stored plurality of digitized data to provide a plurality of digitized data sets as said one or more corresponding portions of a plurality of captured data.

12. The method of claim 1 , wherein said capturing comprises switchably coupling to a respective one of said plurality of data signal transceivers during each one of said first plurality of mutually exclusive time intervals with said second portion of said transceiver tester to receive said respective portion of said plurality of data signal transmissions.

13. The method of claim 1 , wherein said analyzing comprises comparing each respective portion of said plurality of captured data to a respective portion of a plurality of predetermined data.

14. An apparatus including a transceiver tester for testing multiple data signal transceivers substantially simultaneously, comprising:

initiating means for initiating a plurality of data signal transmissions by a plurality of data signal transceivers;

capturing means for capturing, during each one of a first plurality of mutually exclusive time intervals with a second portion of said transceiver tester, a respective portion of said plurality of data signal transmissions from each one of one or more respective ones of said plurality of data signal transceivers to provide one or more corresponding portions of a plurality of captured data, wherein each of said captured portions is less than the entirety of the corresponding data signal transmission; and

analyzing means for analyzing, during each one of a second plurality of time intervals with said second portion of said transceiver tester, one or more respective portions of said plurality of captured data, wherein each one of said second plurality of time intervals follows a respective one of said first plurality of mutually exclusive time intervals.
