A bar code reader/decoder analyzer method and system for testing the quality characteristics of bar code readers and bar code decoders. An analyzer unit is interface with and controlled by host computer which can either be located within the analyzer unit or housed separately. A bar code reader which is to be tested is connected to the analyzer unit and a series or test patterns is scanned. The digitized information from the scanner is converted by the analyzer into quantifiable data and is transmitted to the host computer where it is stored and analyzed. A bar code decoder is connected to the analyzer unit and is sent a series of digitized signals representing a series of scans by a bar code reader of similar type. The decoder decodes the information and transmits the data back to the host computer where the data can be analyzed.
