Verification Tests - C Programs
These programs are designed to do the Functional Verification Tests found
in Chapter 4 - Verification Tests.
This example performs a DAC self test (*TST? command) to ensure that the
DAC is communicating with the mainframe, external controller, and/or
external terminal.
#include <stdio.h>
#include <sicl.h>
#define ADDR "hpib7,9,9"
void main ()
{
INST id;
char a[256] = {0};
id = iopen (ADDR);
itimeout (id, 10000);
ipromptf (id, "*TST?\n", "%t", a);
printf ("\n %s", a);
getchar ();
iclose (id);
}
