Agilent33120A的程序如下：
#include
#include
#include "hp33120a.h"
main ()
{
ViReal64 value;
int i;
ViSession hp33120a;
ViStatus error = VI_SUCCESS;
ViString popUpMsg = "The function generator is outputting the waveform "
"that you configured.\n\nPress to continue";
/*
If you want to run this sample program and the instrument is not
present, set the Simulate flag to 1. (Example: "Simulate = 1")
*/
checkErr( hp33120a_InitWithOptions ("usb0::2391::1031::MY44027032::INSTR", VI_TRUE, VI_TRUE, "Simulate=0,RangeCheck=1,QueryInstrStatus=1,Cache=1", &hp33120a));
checkErr( hp33120a_ConfigureOutputMode (hp33120a, HP33120A_VAL_OUTPUT_FUNC));
checkErr( hp33120a_ConfigureOutputImpedance (hp33120a, "1", 50.0));
for (i=1; ;i++)
{
checkErr( hp33120a_ConfigureStandardWaveform (hp33120a, "1", HP33120A_VAL_WFM_PULSE, 5.0, 2.5, 1000.0, 0.0));
checkErr( hp33120a_ConfigurePulseDutyCycle (hp33120a, i));
checkErr( Ivi_GetAttributeViReal64 (hp33120a, "", HP33120A_ATTR_PULSE_DUTY_CYCLE, 0, &value));
if (value>=90)
break;
}
checkErr( hp33120a_ConfigureOutputEnabled (hp33120a, "1", VI_TRUE));
MessagePopup ("Message", popUpMsg);
Error:
if (error != VI_SUCCESS)
{
ViChar errStr[2048];
ViStatus tmpError;
hp33120a_GetError(hp33120a, &tmpError, 2048, errStr);
MessagePopup ("Error!", errStr);
}
if (hp33120a)
hp33120a_close (hp33120a);
}
我想编写另外一个函数（此函数的代码为上面main函数里的代码），然后用main函数调用它，实现此功能。请问应该怎么做？谢谢
