FSK Signal Generation DAQ Card

[mo_glue]

Hello,

Sorry in advance if this question is inappropriate for the boards, but I didn't know where else to go...

I'm trying to generate an FSK Signal in labview.  I've seen that LabView has FSK modulation tools, but what DAQ card would I need to actually transmit the FSK?  My lab has 6070E and 6534 DAQ cards, could these do the job?

As far as I understand, the FSK modulation vi converts an array of bits into an array of voltages (the FSK signal)... How do I actually output this?

Thanks!

Neil

Neil,

 Here is a great resource for learning what FSK is.

Since this is a type of digital modulation I'm not sure a general DAQ card could do what you want. Maybe someone else could anwer that question.If you look under the example finder in LabVIEW and type in FSK, the examples are mostly related to the Modulation Toolkit. Do you have that toolkit? Which version on LabVIEW do you have?

The more approriate device would be an RF Generator such as the PXI-5441 or similar.

Hope this helps.

Hey Neil,

Check out the following links that you will probably find helpful:

- What Is Frequency Shift Keying? 

- DAQ-STC: Frequency Shift Keying (LabVIEW Example Program using an E-series DAQ board)

- KB: Can I Perform Frequency Shift Keying (FSK) with NI-DAQmx? 

It looks like the example linked above works with E-series DAQ boards, which it looks like you have, so that is good. But it also looks like you will have to use the older version of the DAQ driver - Traditional DAQ, and not DAQmx.

I hope this helps, and should hopefully get you started. Please let us know if there is anything other questions or concerns. Thanks, and have a great day.
