Before your computer can transfer information over the GPIB, it must know how
to access the GPIB board and the spectrum analyzer. The device driver tells it
how. If you are using a National Instruments PCII/IIA board, the device driver is
a program named
GPIB.COM
created and modified by another National Instru-
ments program named
IBCONF.EXE
. If you are using a board from another
manufacturer, the appropriate driver should have accompanied your board.
The device driver program must be installed whenever you wish to use the
GPIB. Use the following procedure. Refer to your DOS manual if you need help
creating or modifying files.
1. Copy
GPIB.COM
to your computer’s root directory.
2. Add the following line to your
CONFIG.SYS
file:
device=GPIB.COM
