Hi Ed? are you saying the 70820 will work at? 50 Ghz ?

?

I have the same rig, more or less - it didn't have the keypad. I think you can do without it and control everything from the screen menus, while the keypad allows for shortcuts to the basic functions, or to operate it with various programs - or maybe not. Anyway, as I recall, I could run it just fine.

I think the keypads for the various uses are all the same inside, with the difference being the button labels. I later acquired a keypad for a different type unit, but have not tried it to see what happens. I think you could probably use the one you have, and just figure out what the button functions should be.

Unless you're going to need its full 40-50 GHz capability, it's best to just adapt the inputs to SMA-compatible types. I bought some short (12") cable type adapters, which were much cheaper than the ideal, simple straight-through barrel types. I made a little box that mounts onto the input connectors, with the cables inside, and SMAs on the right side, to make it less obtrusive in the front.
