Automate HMC703LP4E evaluation

Hi all,

I am evaluating HMC703LP4E evaluation board.  The board is controlled from a PC through the USB interface.  I am trying to measure spurious in small frequency steps.  While the provided GUI is nice, manually changing the frequency and taking spur data is a pain and so time consuming.  I want to write a program to automate t his task.  The problem is I don't know how.  I did some online search including in this board, but couldn't find much info about the steps or where to start.  Could anyone mind explaining to me if this is possible and if it is, what are the steps.  My software/programming level is total newbie, but I have a bit time and wish to explore this area.  Thanks.
