Hi Geoffrey,
Perhaps the ARRL Handbook, Chapter 15 - "DSP and Software Radio
Design", might help? Section 15.6, in particular describes the math
behind calculating the in-phase (I) and quadrature (Q) portions of a
wave form.
As for specific device compatibility with particular software
packages, the release notes for the software should list the hardware
it will work with.
HTH,
