How to Co-ordinate Two Modules

errStatus = viOpen (defaultRM, "GPIB::20::INSTR", VI_NULL,VI_NULL,&vi);

if(errStatus < VI_SUCCESS)

{

printf("Failed to open instrument\n"); exit(errStatus);

}

/* set timeout to 20 sec; this should work for all commands except zeroing */

errStatus = viSetAttribute(vi,VI_ATTR_TMO_VALUE,20000); if (errStatus < VI_SUCCESS) checkError(vi,errStatus);

/* clear error queue */ errStatus = viPrintf(vi,"*CLS\n"); checkError(vi,errStatus);

/* read the wavelength from the laser source */

errStatus = viQueryf(vi,"SOURCE2:CHAN1:WAV?\n","%s",replyBuf); checkError(vi,errStatus);

/* feed the source wavelength into the power meter making sure to measure the maximum power of the source */

errStatus = viPrintf(vi,"SENS1:CHAN1:POW:WAV %s\n",replyBuf); checkError(vi,errStatus);

/* turn auto range on */

errStatus = viPrintf(vi,"SENS1:CHAN1:POW:RANGE:AUTO 1\n"); checkError(vi,errStatus);

/* change the power unit of the power meter to dBm */ errStatus = viPrintf(vi,"SENS1:CHAN1:POW:UNIT 0\n"); checkError(vi,errStatus);

/*set the averaging time for measuring to 20 ms, therefore no timeout needs to implemented */

errStatus = viPrintf(vi,"SENS1:CHAN1:POW:ATIME 0.02\n"); checkError(vi,errStatus);

/* set the attenuation to zero for maximum power */ errStatus = viPrintf(vi,"SOURCE2:CHAN1:POW:ATT 0.0\n"); checkError(vi,errStatus);

/* set the reference mode to the internal one,

which is now the last displayed value */
