ABSTRACT:
A software monitor utility is disclosed which capture and displays General Purpose Interface Bus (GPIB) calls made to GPIB driver software in real time. The GPIB driver software controls a GPIB interface. The GPIB interface is coupled to one or more GPIB instruments. The monitor utility is configured to record and display both the start and end time of a GPIB operation, where end time is the time control is returned to the GPIB application. In addition, for asynchronous GPIB calls, the monitor utility records and displays the end time of the corresponding asynchronous operation. Also, the monitor utility provides the option of substituting a monitor-enabled version of a key driver module for a non-enabled version upon entrance to the utility. Furthermore, an option of provided for restoration of the non-monitor-enabled version upon exit from the utility.
