Verification Tests - C Programs

Test

This program is designed to do the Functional Verification Test found

in Chapter 2 - Verification Tests.

Example: Self Test The self test for Agilent E1346A Single Ended Relay Multiplexer

consists of sending the *IDN? command and checking the response.

This test can be used to verify that the multiplexer is connected properly

and is responding to a baxic command.

NOTE

This program assumes a primary address of 09 and a secondary address of

14. If your Multiplexer address does not match this, you must either

change the Multiplexers address setting or change the program line

# define ADDR "hpib7,9,14" to match your Multiplexers address setting.

# include < stdio.h>

# include < sicl.h>

# define ADDR "hpib7,9,14" /* Address of device */

void main (void)

{

INST id; /* Define id as an instrument */

char a[256] = { 0} ; /* Result variable * /

int i;

ionerror (I_ERROR_EXIT);

id = iopen (ADDR); /* Open instrument session */

iprint(id, "*IDN?\ n"); /*Send *IDN? command */

iscanf(id, "%t", a); /*Get response */

printf("\ n %s", a); /* Print result */

getchar(); /* Pause */

iclose (id); /* Close instrument session */

}
