IQ output

[afd-2000]

I have sent interleaved I and Q values to the DAC, and need to deinterleave them in the Host VI so that I can view the power spectrum of the signal.  I've looked at the IQ output example, but this VI doesn't seem to do any deinterleaving.  Can this sort of mechanism be found in any of the examples that were provided with the software?

Hi

I’m not sure what format your data is in.  But if it is a simple array of I16s of interleaved I and Q data, there are various ways of de-interleaving the data.  There is the brute force approach of wire the data into a For Loop and alternately filling two other half sized arrays.  There is a function in the Functions>>Arrays palette called Decimate 1D Array that would do this as well.

Jerry,

I actually searched around in the toolbar and found the decimate array block awhile ago, which worked perfectly.  Thanks anyway though.
