I'm aware I get too excited and interrupt, and I'm getting better at that. The problem has always been that I think of something to ask in the moment and fear that I'll forget to ask, but now I try and store it for later. It's not easy doing that without taking notes like a professional interviewer often would.

IMO, you are a professional interviewer ! This interview was well done and you asked all the good questions that I had in mind. I was so positively surprised how openly John was answering some of your questions and more.

This interview is a tremendously good source of information for us here at the forum but likely it is even more valuable for Keysight. Actually I think it is priceless for Keysight, advertisement they could not buy for any amount of money.

9:10 in the thrid video "So I actually managed the two guys working on [the replacement for the 3458a] the first time we tried to do a replacement on it". That phrasing (the first time) makes me believe either they have tried a second time later on and given up again, or are (and I think this is the more likely scenario) indeed working on a replacement right now.? I would imagine that if they weren't, he would have said "I managed the guys when we looked at making a replacement" or somethign along those lines.

In addition, these are some excellent interviews. They are really top quality material. Dave, you are (well were) doing an excellent job of letting him speak and allowing him to finish his sentences, something that you seemed to have issues with in your interviews back in the earlier days of the EEVBlog. In addition, John Kenny is clearly a great teacher/speaker, with his calm and well through-out phrasing and talking. I would love to see more of this on the EEVBlog.

Curious to know when this was recorded as the Santa Rosa HQ office has been affected by the fires over there, though I am not sure to what extent. Any info?

The buildings are fine, but power was still cut as of Monday when John mentioned it.

That is good to hear! I heard in the local research centers that there was rumors that their fab was in great danger. If they lost that, I don't want to know the impact for their high-end RF market would have been.

Keysight products generally costs a bit more money than I'm prepared to spend. Now I have more respect for why that is than I what previously had. These videos made such an impression on me that I now own some stock in the Keysight company, You'd need something equivalent of a 3458 to pick my stake in last digit but never the less :-)

Well done indeed Dave & John, very interesting and enjoyable to watch and listen to!

I think this visit by John Kenny, that fab interview, is so good,  that it is more worth to Keysight than their whole add budget! It gives a trust to the products , the people behind and the company that will bring a lot of new customers. I wil also get the atention from hobbyist and users that normaly goes for cheaper products. Well done.. a act for other instrument companies to follow! Great show Dave!

It is good to hear what the thinking behind the strategies of T&M manufacturers like HP/Agilent/Keysight is, as in recent years there has been a lot of convergence in the approach to instruments and what they will offer in terms of functionality and price and I am sure a large numbers of buyers of mid range equipment have found that with all the offers coming from the major manufacturers (Keysight included) that the market has become a bit muddled.

One thing that still holds true is that if you get hold of an older piece of equipment labelled HP, you know it is generally going to be maintainable and a solid bit of kit, I am not sure the same will be said of Keysight branded models in 10 or 20 years time as I get the impression that these days they are more focused on selling the latest gizmo rather than supporting the customer on something they made 5 or 10 years ago, which almost make you think they are designing in obsolescence through support rather that the old HP approach of providing the best kit they could that would last well into the future, in fact this is what HP got it's name for, so maybe the loss of the HP identity is in fact an indicator of the way the company is going, I truly hope it is not the future and that given time the Keysight name will come to mean the same as the HP logo did.

I own various bits of HP/Agilent/Keysight gear with a wide range of ages and each generation has it's pros and cons. Old gear may contain parts which are no longer available where newer gear has complex things like displays which may go bad. Overall my impression is that each generation can be repaired because what fails most is power (related) electronics, wear sensitive parts like relays and parts which get hot.

Excellent Interview! :clap: :clap: :clap:
At part four Dave mentioned something about internal project code names and John mentioned marsupial.
I think Dave read it when he read through the serial dump while hacking the 1000X series scope. :-BROKE

I have to ask: there appears to be a stack of multimeters in the back, one of which looks a lot like the mentioned copycat model, and the others may have similarities as well. Was that a complete accident?

Nooo :( .... <chant> We want more! We want more!

Have really enjoyed this series and it's just made me more determined to upgrade from Rigol to Keysight in a few years.

Many thanks to you, John Kenny and Mr Invisible :)

Nope, very deliberate copy:

Sorry, I wasn't very clear. I mean whether the placement of what looks to be the copycat device in the background during the interview was an accident, or a deliberate move, as the subject was bound to come up. Considering how the GW121 has been casually popping up all over the place, I can imagine this is a way of having a little fun with the viewer.

If you'd rather keep it a mystery, that's fine too ;D

Nope, nothing placed on purpose.

Dave, really a great series of interviews. I am certainly intrigued about what he meant by "watch this space" re the function generator functions of their scopes. I have a 3000T series and I must admit I think the arb generator function is absolute crap.

 I caught that as well, it confirms Dr Frank's assertion on the forum that they tried at least once and failed. I believe Dr Frank has inside contacts there. John mentioned ruefully the one original designer  is still working, but working for the competition. That must be Wayne Goeke/ Fluke I think.

Well, I had personal phone contacts to Keysight people, when discussing with them these bugs on the 34465/470A ACAL DCV function.
Scott Stever was in the phone call, being introduced as the project manager for the 34465/470 DMMs.

Wayne Goeke is obviously responsible for the DMMs at Keithley, as the patent implies.

Both were the main engineers for the 3458As A/D, as can be seen in the hpj 4/1989, page 98.


This interview is really great and very interesting, regarding international development processes.
Would like to see more of videos like this.

What I was surprised to hear is that HP developed the LTZ1000. I thought it was Bob Dobkin, Carl Nelson and Jim Williams (based on his LT1088) at Linear.

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.
