why does my ouput signal produce triangle waves when i want sine waves

[reggie2016]

in labview i use daq assistant to create a output voltage signal to create a sine wave. when i connect it to the opscilloscope it reads triangle waves. can someone please tell me why this is.

try increasing the update rate...if it doesn't update but a few points per period it might look like a triangle...

what HW are you using?

[reggie2016]

i am using ni cdaq9172

when i run the test run it works fine but when i generate the code from the daq assistant thats when it produces the triangle waves.

9172 is a chassis so I would need to know the module you are using, too. You should try the example:

%PROGRAMFILES%\National Instruments\LabVIEW 2012\examples\DAQmx\Analog Output\Voltage - Continuous Output.vi

It shows you how to create a waveform to generate, you could use that piece and feed it into your daq assistant.
