DAQ for creating 2 output channels at 1MHz each

Hello everyone,

I'm currently working on a project and i would need to sync two different signal generators at the frequency of 1MHz. Now, since both of them have a single channel output and there is no way to sync them (they are too old and the required part to connect them in so more available), i should buy a 2-channel signal generator.

Someone suggested me to use a DAQ and Labview instead of buying a new expensive signal generator; I've read many posts about DAQs, as well as their datasheet, and I'm pretty sure that generating a 1MHz sinusoid on two analog output channels at the same time is impossible. Am i right or is there any DAQ model powerful enough for this task?

 

Thank you very much.

Hi Masco89,

 

-You mention that the two channels need to be synchronized- how tightly synchronized do they need to be? Have you thought about how much clock drift, skew, and jitter are allowable in your system?

 

-What kind of signal are you looking to output? Sinusoid, square, custom waveform? If square, what voltage levels will you need? This will help determine what style of output your DAQ device needs to support.

 

-What are the synchronized signals being used for?

 

Your best bet for questions like this, where you're trying to narrow down which of our products will be best for your application, is generally going to be to call in and talk to one of our Sales Engineers. They're going to be most familiar with our whole line of devices, and can give you more specific guidance than you're likely to find on our forums. Check out the "Purchase and Quote" options on this page for more info about how to get in contact with them.

Hi  Kathryn,

 

 

I think you are right, maybe i should just call and talk to one of your Sales Engineers in order to idenify the right device.

Thanks for your reply.
