Remote Operation
Monitoring the Instrument
Operation Status Structure
Contains bits that report on the instrument’s normal operation. Additional
transition filters give you the ability to select the logic transitions which set
the event register bits. For example, you can define the Measuring bit of the
Operation Status Structure to be set when a status line transitions from false
to true. This is a positive transition. You can also specify a negative transition
where bits are set when a status line transitions from true to false.
