Status Reporting
Status reporting is used to monitor the U8480 Series to determine when events
have occurred. Status reporting is accomplished by configuring and reading
status registers.
The U8480 Series has the following main registers:
–Status Register
– Standard Event Register
– Operation Status Register
– Questionable Status Register
– Device Status Register
There are other registers that exist “behind” the main registers, and they are
described later in this chapter.
Status and Standard Event registers are read using the IEEE-488.2 common
commands.
Operation and Questionable Status registers are read using the SCPI STATus
command subsystem.
The general status register model
The generalized status register model shown in Figure 1-11 is the building block
of the SCPI status system. This model consists of a condition register, a transition
filter, an event register, and an enable register. A set of these registers is called a
status group.
