Is it possible to maintain the last AO value after the DAQmx task is done on device DAQ USB-6341 ?

[godel]

Hi all,

I use the device DAQ USB-6341 to generate the desired voltage waveform by the "finite samples" sample mode.

I notice that the channel resets to zero volts after the DAQmx task is done and the DAQ USB-6341 does not have 

the property AO.idleOutputBehavior to select "Maintain Existing Value".

How can I maintain the last AO value after the DAQmx task is done on device DAQ USB-6341 ?

Thanks.
