Connect it via USB and open the serial port in a terminal program, bitrate etc. is not relevant. Type e.g. "help" to see the available commands.

Re: Buying new VNA
I have the H H4 SAA2N and the F models and use them in different applications. If you intend to use it outdoors I strongly recommend the F model with the pushbuttons. It has the brightest display

Re: Unwrapping Phase
Yeah, derivatives do accentuate noise - but sometimes that's actually useful to spot a discontinuity in a system that should otherwise be "smooth" And when you have multiple resonances, is makes them

Re: Unwrapping Phase
Make sure you are taking frequency steps that are small wrt to the DUT bandwidth. GD on a xtal filter is one example.
