Abstract

An IEEE 1394 serial bus network data capture and analyzer device is coupled within an IEEE 1394 serial bus network for monitoring, capturing and analyzing data communications transmitted over the IEEE 1394 serial bus network. The data capture and analyzer device is preferably implemented within a computer system and includes an IEEE 1394 serial bus network interface card for communicating over the IEEE 1394 serial bus. The data capture and analyzer device also includes a user interface which is displayed on a display device coupled to the computer system. Through the user interface and input devices coupled to the computer system, a user selects a function to be performed by the data capture and analyzer device. Preferably, the functions allow a user, through the data capture and analyzer device, to at least trigger on a specific packet header, field or data pattern, trigger on an error and capture a specific time or cycle event. Captured data is stored within an internal memory of the computer system. From the internal memory, data is stored on a mass storage device, floppy disk or tape media. Captured data is also displayed for the user through the user interface and printed on a printer thereby allowing a user to analyze and record the data communications for testing and monitoring of the communications over the IEEE 1394 serial bus.
