A/D convertor in LabVIEW using a DAQ?

[butterwaffle]

I am a student who is a beginner in LabVIEW.. I was wondering about making a A/D convertor in LabVIEW using a DAQ? Any helps in leading me to the right direction?

The DAQ is an A/D converter.  What are you trying to measure?  What DAQ do you have?

I want to use LabVIEW to generate a sinusoidal signal which can have changing frequency and amplitude and then be abel to throw the signal into a A/D converter to display the digital form as a graph. I was wondering if anybody can help lead me to the right direction?

In your original post, you've said that you've taken some tutorials and could not understand them. Without knowing what you took and the exact nature of your problems, it's hard to recommend something when it might be something you've already tried. I would hope that you've looked at Help> Find Examples or tried the DAQ Assistant. What you are attempting is very basic. Have you at least installed DAQmx and tested the device and your wiring in Measurement and Automation Explorer (MAX)?

I've done of the tutorials by NI, and well to be honest they weren't very useful.

Is there a way to convert my analog data into digital data and then display the digital data on the graph?

To be honest, you seem to misunderstand quite a bit. Please be specific about the actual tutorial you took. There are numerous ones.

Did you do anything at all that I asked about (i.e. test it in MAX)? With a simple DAQ Assistant, the hardware wil convert the signal and the DAQmx driver will return an array of values to your program. One function wired to a graph and you are done.

Yes I have tested it in MAX

Basically this is what I have..

I simulated a signal and put that into analog output.. This output goes into an analog input(I made a closed loop with my NI USB6353). This input gets converted into a digital waveform. I want to have this digital waveform graphed out into my block diagram. Here's my VI

Can you attach an image? I'm using my phone right now.

Here you go

You've already got a graph with a DAQ Assistant to do the read. Everything with the digital stuff and the other DAQ Assistant is just silly.
