Abstract
Abstract The programmable protocol analyzer enables a user to specify (102-106) one or more fields (501-526) that are to be monitored (107-109) by the protocol analyzer and displayed (110-111) to the user. The specified fields (501-526) can be selected (103-104) from a menu of predefined fields (501-526) in the frame of data or can be user defined fields (524) of arbitrary length and position in the frame (Frame) of data. The programmable protocol analyzer excerpts (107-109) these specified fields (501-526) from the transmitted frame (Frame) of data, stores the specified fields (501-526) in a memory and displays (110-111) the data contained in the specified fields (501-526) to the user. This programmable protocol analyzer thereby permits a user to monitor and display only the particular segments of the frame (Frame) of data that are of interest to the user. This arrangement filters out the extraneous information contained in the frame (Frame) of data in order that the user can concentrate on only the particular fields (501-526) that are most relevant to the test being performed by the user.
