Remote
Prog
EXAMPLE
The following application program
is
written in C for the
IBM
PC-AT. The National Instrun
Model AT-GPIB board provides the interface between the PC and the Fluke
884OA
DMU
program assumes that the configuration program IBCONF
has
been
run
to initialize the inte:
board
with
the device name I8840A assigned to the
GPI~O
board.
This program illusmtes a method of recording any
errors
produced by the 8840A selfrest func
It should be noted that:
1.
If more than one digital error occurs, only the last one
will
be reported.
2. The response to a Get Insaument Config. (GO) comxhnd during sekftar
is
"9xxx".
3.
The response to a Get
Em
Status
(G7)
command
4th
no
umrs
present
is
"1000".
