Oh, Keysight gear doesn't hold a candle to vintage Hewlett-Packard. However, I just wanted to argue that Keysight is closer to Bill & Dave's garage than the current HP incarnation. They have some OK gear, but too much of it seems overpriced; they are definitely letting the cheaper Chinese manufacturers catch up to them and seem to only want to rely on institutional contracts.
I personally don't know anyone in the hobbyist electronics space that owns any Keysight gear, my only exposure has been in university labs. Bit of a shame, really.
Yeah it's kind of crazy what HP was able to accomplish, the reason keysight hasn't updated a lot is because they didn't really have to. The DAQs are incremental improvements from what I've seen, the aforementioned 3458A still competes with new instruments, and I honestly enjoyed the 54601A scopes I used in school more than the new Tek ones I have at work.
They are not as affordable as chinese counterparts (Rigol or Siglent) but their 1000x line of scopes is a step in a good direction. I own one although I paid more for less features as compared to Rigol, difference in quality and polish of the UI is staggering.
