Description

ABSTRACT:
An analyzer which can record the events occuring on an ATA computer bus and provide an easily understandable, yet detailed description of those events to either a local user, or a remote user, for the purpose of diagnosing an ATA related problem or measuring performance. The analyzer is small and portable, simple to operate, and capable of transferring recorded data to almost any computer through an RS232 serial port. The invention has a memory system which stores the recorded signals or events, a trigger circuit used to select the starting and stopping point of the recording, an event recognition circuit which can limit the recording to certain events, and a processor which can interpret the data and display it to a user on the built-in displays, or on a printout, or on a local or remote terminal. Additionally, the ATA analyzer will search its recorded memory for an event specified by the user and display any occurance of that event.
