EXAMPLE 1:
USE OF THE INTERACTIVE
GPIB PROGRAM ’IBIC’
This example assumes the use of an lBM PC, oracompatiblecomput-
er, equipped with a National Instruments GPIB interface card. It also
assumes that the GPIB-driver is left in the default state so that the
device name "dev4" corresponds to the GPIB address 4 which is as-
sumed to be the address of the oscilloscope. All text entered by the
user is underlined.
