Beginning of Program

/* This program resets the E1563A/E1564A, reads the ID Register, the Device */ /* Type Register, the Status Register, makes measurements and retrieves data*/ /* Programmed with MS Visual C++ version 2.0 using Agilent VISA I/O calls. */

#include <visa.h> #include <stdio.h> #include <stdlib.h> #include <string.h> #include <time.h>

/* function prototypes */ void err_handler();

void wait (int wait_seconds);

void reset(ViSession vi, ViStatus x);

Program Main

void main(void)

{

unsigned short id_reg, dt_reg;/* ID and Device Type */ unsigned short stat_reg; /* Status Register */

unsigned short cvt_reg, cache_reg; /* last value and cache registers */ double last_reading, reading; /* decimal values of readings */

int i;

/* create and open a device session */ ViStatus err;

ViSession defaultRM, digitizer; ViOpenDefaultRM(&defaultRM); /* GPIB interface address is 9 */

/* digitizer logical address switch = 40 (factory setting) */ ViOpen(defaultRM,”GPIB-VXI0::9::40”,VI_NULL,VI_NULL,&digitizer);

/* reset the E1563A/E1564A */ reset(digitizer, err);

Read ID and Device Type Registers

/********* read the digitizer's ID and Device Type registers *********/

err=ViIn16(digitizer,VI_A16_SPACE,0x00,&id_reg);	/* read reg 00 */
if (err<VI_SUCCESS) err_handler(digitizer,err);
err=ViIn16(digitizer,VI_A16_SPACE,0x02,&dt_reg);	/* read reg 02 */
if (err<VI_SUCCESS) err_handler(digitizer,err);
printf(“ID register = 0x%4X\n”,id_reg)
printf(“Device Type register = 0x%4X\n”,dt_reg);
