An overview of the oscilloscope's status reporting structure is shown in
Figure 2 . The status reporting structure shows you how to monitor
specific events in the oscilloscope. Monitoring these events lets you
determine the status of an operation, the availability and reliability of the
measured data, and more.
• To monitor an event, first clear the event, then enable the event. All of
the events are cleared when you initialize the oscilloscope.
• To generate a service request (SRQ) interrupt to an external computer,
enable at least one bit in the Status Byte Register.
