Error -200077 with NI USB-6008

[msamman]

I am trying to run the sample C program that came with my NI USB-6008 DAQ card. I am trying to run the "ContGen-ExtClk.c" example. I get the following error when I build the program:

DAQmx Error: Requested value is not a supported value for this property. The property value may be invalide because it conflicts with another property.

Property: DAQmx_SampTimingType

Requested Valeu: DAQmx_Val_SampClk

You Can Select: DAQmx_Val_OnDemand

Task Name: _unnamedTask<0>

Status Code: -200077

End of program, press Enter key to quit

Thanks for any help.

Did you do a search for that error code? As you can see from the specs for the 6008, the analog output is only software timed so you can only select OnDemand timing. Your actual update rate is going to vary quite a bit and, according to the specs, have a max of 150S/s.

Cool Thanks!
