I have an Anritsu Cell Master, model 8212B I think. It’s sweep rate it way too slow in transmission measurement mode to be useful for tuning duplexers or filters, you have to tweak, wait for the trace, overcompensate, wait, undo what you did, wait, tweak again, wait…. Its fine and accurate for verifying something but that’s it.
?
I got mine off eBay for $350 and it’s been good for the spectrum analyzer to 4GHz, although its sweep is slow and for testing antennas and measuring low power levels. Mine has a bunch of defunct cell phone testing modes and a guy on another four un who worked at a cell phone company turned me on the the eBay ads from his company that was disposing of the units cheap. Knowing what I know now about these I would not pay any more for one.?
I have no experience with the Y400.?
