DAQ assistant

[jonssc]

Hello.

I am begining to acquire signals with Labview 8.5.

 Well, I have created a DAQ assistant to see my signal in a Wavegraph. ( I am acquiring an output analog voltage signal with sinosoidal form) . I can see a great signal when I look in the " Connection Diagram " of the DAQ assistant panel. it is just what I´m looking for and it move in a perfect real time when I change the signal. The question is how can I get the similar signal in a Wavegraph in the Block Diagram?I have tried it changing the parameters like rate, amplitude... but I have only got changing straight lines and these are very diferent of the sinosoidal form of the connection diagram.

I´m not very good with Labview but anybody knows some trick to watch in the block diagram the good signals of the connection diagram?

Thank you very much!!

Please post the VI that is demonstrating this problem.  You save "wavegraph" is that a Waveform graph or a waveform chart?  My first guess would be that either the X-range of the chart is too small and you are only seeing a very small portion of the sine wave at once.  Or you are using a waveform graph which gives new information on each iteration, and you DAQ assistant is only capture a small section of the sine wave on each iteration.  Look at your number of samples vs. sample rate vs. frequency of the signal.
