True on the hardware. Beyond that it depends on how they architected the firmware/software if the UI code is well separated from the underneath bits. Most of the firmware hacks I've seen posted are reasonably safe and reversible to try but only for a very specific model. After I posted I finally saw a note from OP of the "thou shalt not" try on other models...
Was hoping it might be possible to safely kill normal UI process and try out OP's much better UI. Odds of that actually working are low, but thought I'd ask. I'm not up to speed enough to hack around with it myself yet, need to get through a few more learning curves with JTAG and the like.
(*Sarcastic*) And thanks a lot for bringing up the SSA3000X+ "upgrade". It took months to convince myself to wait until next year before digging into the RF side of things and getting related "field upgradable" SA/VNA toys... -ER-, I mean essential tools.
... SVA? Sounds like I'm behind on reading. But I really, really shouldn't catch up. Bad idea. Bad, bad idea. I don't go to TEA meetings. I don't have a problem.
