If you're not using Rohde & Schwarz equipment, you're a nobody...

I own 2 Planar R54s by Copper mountain technology.

I use these when I teach antenna and line sweeping at IWCE. Like Fred mentioned way back at the start of this thread, using a laptop for control and display is a big deal to me. I can put this and a small tablet in a pants pocket and have both hands free to climb a ladder to test an antenna on the roof.

Another advantage is no phase stable cable needed, this is small enough to leave hanging from the coax with a much more flexible USB cable to the PC.

It also makes it easy to show the screen on a projector in class. Copper mountain just announced they have a Linux version of the software.

Better than an Anritsu but still no match for the mighty Agilent Field Fox. The unit I use is fully loaded, goes to 50GHz and cost north of $100k, and that's with a friendly Agilent rep. Its an entire microwave lab in a box no bigger than the R&S you linked.

AEA's last Beta unit just got approved for production on their two port VNA on their Liberator line (which isn't up on the website yet but you may have seen the demo's over the last few months). What makes it different is it's software definable architecture but it currently has the VNA, RL bridge, TDR, FDR, spectrum analyzer (which is fairly quick), and a tracking generator. First revision is only DC to 1.3 GHz but the second release is going to be through the 6 GHz microwave band. The 1.3 GHz version is around $2500.
