Waveforms SDK wavegen question

[Juan Castillo]

Hi at all,

I need generate a custom signal from an array. If the values in the array are bellow 1, the signal was generated correctly, but if the values in the array are beyond 1v, the generator truncates the output to 1v. The same happend with negative values. Whats happend? here is the code:
 

# signal_array contains custom values between -3 and 3, but the generator truncs to -1 and 1

1. dwf.FDwfAnalogOutNodeEnableSet(hdwf, c_int(0), AnalogOutNodeCarrier, c_int(1))  
2. dwf.FDwfAnalogOutNodeFunctionSet(hdwf, c_int(0), AnalogOutNodeCarrier, funcCustom)
3. dwf.FDwfAnalogOutNodeDataSet(hdwf, c_int(0), AnalogOutNodeCarrier, signal_array, c_int(len(signal_array)))
4.  dwf.FDwfAnalogOutConfigure(hdwf, c_int(0), c_int(1))  
5. Thank you very much

 

Regards
