Using the Instrument Status Registers
You can determine the state of certain instrument hardware and
firmware events and conditions by programming the status register
system. The Figure on page 76 shows all the instrument status
registers and their hierarchy. The IEEE common (*) commands access
the higher-level summary registers. To access the status information
from specific registers you would use the STATus commands in Chapter
5 , “Language Reference.”
