Live Updating Analog Waveform Generation

Solved!
Go to solution

Is there any way I can modify this VI to allow real-time changes in the frequency, phase, amplitude, and waveform type to be output continuously through an NI 9263 DAQ? At the moment, changes made in these variables only will pass into the output signal if the program has these variables set properly at runtime.

Hi Zach,

 

this VI already allows to change the waveform parameters. When there is a value change event the waveform will get updated to reflect these changes!

Best regards,

I see this update in the waveform viewer on the computer, but I actually do not see this output change on my oscilloscope. Do you have any idea why that might be?

Hi Zach,

 

do you get any errors from the DAQmx functions?

Which DAQ hardware do you use?

Best regards,
GerdW

I don't get any errors from the DAQmx functions, and I'm using the NI 6263 DAQ module, with a 9181 case.

Solution to this problem:

 

I found this VI, and it allows me to have the hardware buffer to be continuously updated with new signal information. The 2010 version of this works great for me to output live-updating signals through my NI 9263 measurement system.
