I have an older scope from link instruments, the signal hound, and will construct one of the very simple component bridges ( uses a dual op amp and a couple of resistors and the sound card). As I mentioned, there's a good power meter from Mini-circuits, and the ham radio QEX periodical has some designs for a VNA albeit not at microwave frequenies...

I think it would be possible to build a microwave front end for, say the tentec tapr VNA.  A nice quiet synthesized LO, etc
