What I also found very interesting from John to hear about the reasons, why detailed Schematics are no longer included in service manuals:
1. Other companies copied them (Very obvious)
2. Keysight would need to offer service / explanations for schematics

It would never have crossed my mind to call Keysight and have them explain a certain part of a schematic to me. But it seems that was the case and took valuable time away from them.

I just finished part 5.
Again, thank you Dave and John for such wonderful interview!

Oh Keysight, please stick with the knobs and physical controls. In fact, the final thing that made Keysight win our last "what scope do we want buy" shootout was the separate knobs for each channel (and the MegaZoom instant response). We recently got a new function gen with the unified front panel you discussed and it's not the most loved instrument because the new front panel has eaten away the hard output on/off button (and the power supply makes whining noises when it's powered off) so please make wise choices about the front panels.

I own and generally like HP/Agilent/Keysight products so I bought one of those function gens for the company I work for. Great piece of equipment. But the whining PSU and lack of output on/off buttons where practically the only reasons I went with Siglent SDG 2000X Series for my home lab instead of the Keysight one I originally planned on buying. Didn't absolutely need the isolated outputs and the level of accuracy at home.

Oh and I have to say - excellent series of interviews! Definitely would like to see more like these.

1000% agree with the knobs....  KEYSIGHT - PLEASE KEEP THE KNOBS!

Why? (if it's not obvious) - Quick and intuitive changes of setting.  If there is an operational parameter that I will change frequently, then I NEED to be able to do that quickly and easily.  A two-step process is double the work it needs to be - and if you bury such a setting behind 3 or 4 button pushes, then it's that much more to do to actually change that parameter.  Put a knob in front of me that only does that one thing - and I will be happy - because no matter how everything else is configured, if I want to change that parameter, I can just go straight to the knob.

A function tree structure 10 wide and 10 deep may give you 100 discrete options - but you may have to traverse through up to 20 steps to find the one you're after ... and that's assuming you know where to go to get to it.  (The learning curve for that little exercise can be frustrating - but it is the sort of thing that will lock people into your product line ... if the interface is consistent, that is.)

For the proponents of the "clean look" front panel - don't go overboard.  Sure, you can build a scope with a screen on one side and a MS "Knob" on the other and you can get it to do everything - but I won't be using it.

KEEP THE KNOBS

Yeah, I don't understand why you can't have them and refuse support on them if it came to that. But yeah, maybe the shear number of people causes X number of people who will expect support.

Probably something related to "If you give a mouse a cookie, then he'll ask you for a glass of milk." Granted I would think the majority of people don't expect any further help but, as you hypothesized, it only takes a few out of many to become a burden.
