Forgive my ignorance, but why would this be a bad thing?
Only for a handful of forum members. For everybody else it's good.
I just got mine today, and wondering to apply the 'upgrade' now or wait until new firmware comes out.
a) You might already have the latest version.
b) Firmware updates
don't magically transform your oscilloscope and make
everything better. If you're not blocked by a very specific problem that you
know is fixed by updating the firmware then I say leave it alone.
"If it ain't broke, don't fix it".
Plus: There's always a very tiny (but non-zero) chance that an update will go horribly wrong and brick your scope.
Me? I haven't applied last November's update yet. I'd probably do it it I needed a better FFT, but I don't, so...
PS: It's really up to you. I'm old and wise but you just got a new 'scope and want it to be the best 'scope it can be(!) I'd understand.
