Programming Fundamentals
Overview of the GPIB Bus
• A clear function that causes all GPIB instruments, or addressed
instruments, to assume a cleared condition. The definition of clear is
unique for each instrument (sometimes called: clear, reset, control,
send).
• An output function that is used to send function commands and data
commands from the controller to the addressed instrument
(sometimes called: output, control, convert, image, iobuffer,
transfer).
• An enter function that is the complement of the output function and
is used to transfer data from the addressed instrument to the
controller (sometimes called: enter, convert, image, iobuffer, on
timeout, set timeout, transfer).
