Hello,

just a simple example to generate a sinus on 2 output channels:

    DAQmxCreateTask("",&taskHandleCH1_2);
    DAQmxCreateAOVoltageChan(taskHandleCH1_2,"Dev1/ao0:1","",-10.0,10.0,DAQmx_Val_Volts,NULL);
    DAQmxCfgSampClkTiming (taskHandleCH1_2, "",Frequency * Samples, DAQmx_Val_Rising, DAQmx_Val_ContSamps, Samples);

    //Sinus on channel1

    SineWave (Samples, Amplitude , 1.0/ (double)Samples, &Phase, Sinus);

    //Sinus on channel2
    SineWave (Samples, Amplitude , 1.0/ (double)Samples, &Phase, Sinus+Samples);
  
    /*********************************************/
    // DAQmx Write Code
    /*********************************************/
    // Channel 1 and 2
    DAQmxWriteAnalogF64 (taskHandleCH1_2, Samples, 0, 10.0, DAQmx_Val_GroupByChannel,
                         Sinus, NULL, NULL);


    /*********************************************/
    // DAQmx Start Code
    /*********************************************/
    DAQmxStartTask(taskHandleCH1_2);

I just test this with ni pxi4461 and it works fine.
