I noticed that you've posted a couple of other messages here and here regarding this same instrument. Have you submitted a request for the driver on our instrument driver network? If you haven't, you can start that process here.
As there is not currently a driver for this instrument, and if you want to continue developing a driver on your own, the best place to start from is most likely another DSA Instrument driver, such as the 35670A, that you mention in another thread. Because they are definitely different devices, you will need to make appropriate changes to the driver to ensure that it works with you instrument. I would recommend that you start with the basic functions of initializing the device and closing out a session to the device. Once you have verified that you are doing these functions correctly, then begin branching into the configuration and measurement functions. You'll need a programming manual for the 35665A, which I couldn't find on Agilent's website - perhaps because they discontinued this product about 2 years ago. It will take some time on your part to get build the driver.
I guess the last thing that comes to my mind is a question - what is your end goal? Do you want to be able to build multiple test systems and configurations, or are you just designing a single test set up? How large of an application are you planning on building? In some cases, you might be able to get up and running just using VISA to communicate with your device - using simple reads, and writes, property nodes and events. But this really depends on how much time you have, how far you've gotten with your current driver, etc.
