以下是一个使用C语言编写的VISA编程的例子:
#include <visa.h>
#include <stdio.h>
int main()
{
ViSession defaultRM, vi;
ViStatus status;
// open the VISA resource manager
status = viOpenDefaultRM(&defaultRM);
if (status != VI_SUCCESS) {
printf("Could not open VISA resource manager\n");
return 1;
}
// open a connection to the GPIB device at address 17
status = viOpen(defaultRM, "GPIB0::17::INSTR", VI_NULL, VI_NULL, &vi);
if (status != VI_SUCCESS) {
printf("Could not open GPIB device\n");
viClose(defaultRM);
return 1;
}
// send a query to the device
char response[100];
status = viQueryf(vi, "*IDN?\n", "%s", response);
if (status != VI_SUCCESS) {
printf("Could not send query to device\n");
viClose(vi);
viClose(defaultRM);
return 1;
}
printf("Device ID: %s\n", response);
// close the connection to the device and the resource manager
viClose(vi);
viClose(defaultRM);
return 0;
}
