Configuration Example
/** FUNCTION PROTOTYPES **/
void main (void);
void err_handler(ViSession vi, ViStatus x);
void sys_err(ViSession resource);
/** GLOBAL **/
ViStatus err;
ViSession defaultRM, cmd, dac, dmm;
int num_chan;
void main (void)
{
int i,result = {0},config [6]={0},num_chan = {0};
err=viPrintf(dac, "DIAG:CONF?\n");
if(err VI_SUCCESS) err_handler(dac, err);
err=viScanf(dac, "%,6d", &config);
if(err VI_SUCCESS) err_handler(dac, err);
sys_err (dac);
Chapter 3
For example, if the following six integers are returned, the module has the
configuration indicated.
Integer Decimal
Value
1st 7
2nd 7
3rd -1
4th -1
5th -1
6th -1
The following program segment demonstrates how to read the module
identification string and the configuration. The configuration integers are bit
manipulated using the C operator for bit shifting
result = result <<1
(a one bit shift to the left). The code shown in this example can be obtained
from the file prftest.c on the examples disk provided with this manual.
/* VTL error routine
/* Checks for SCPI programming errors */
/* request module configuration */
/* returns six integers
/* SCPI error check */
