Re: HP YIG replacement 3-7GHz
The experience i made dealing with people is that most folks want turnkey solutions, which means if you want to pursue this you would have to put together a kit and offer it which adresses the mechanical interface as well as electrical interface , but then
you also have to adress the potential legal ramifications by adding appropriate disclaimers that you can¡¯t guarantee original specs blah blah blah and so on?

Years ago I talked to a retired HP engineer at a IEEE MTTS event , he said that the projected lifespan HP was designing and testing for was 10-15 years depending on the target market and price so many pieces we are using today have by far outlived their useable life

Re: Recommendation for an "up to 1GHz" generator + sweeper
I've seen mostly HPAK, with a few scattered R&S boxes at Powerwave Technologies (RIP), Broadcom, and Raytheon where I've worked over the past 2 decades.? R&S spec ans were used at Pwave for demanding test apps like >60 dBc adjacent channel leakage ratio.? But most benches had HP (1939-1999) or Agilent (1999-2014) boxes on them.? Pwave laid me and a bunch of others off in 2003 and then went under almost exactly 10 years later.

Rohde is definatly more prevalent in Europe compared to the US but they have taken a good chunk of agilents turf here in the US over the past 10 years or so , when I worked at nokia back in 2007 we were looking to buy VSG to test LTE Radios
, we spend 4? months comparing agilent and rohde SMU and rohde clearly came out way ahead of agilent
?
?
I will definitely explore the R&S path, but direct accessibility of in-house repair (my house!) is a big factor. Half of the fun for me is fixing, maintaining, adjusting/calibrating these instruments.?
?
But the integration of the R&S between their RF and AF lines seems pretty amazing. On the audio side of things, the AP vs R&S debate is heated enough, but AP has no RF division, obviously. Probably Keysight/Agilent era units may provide
such integration, but nowhere near my affordability.?
On the HP 8662A - the? FM distortion seems surprisingly terrible... I have not seen over 1% distortion listed on any instrument of any type I've been looking at in a while... Am I missing something?

radio gear, so probably with test equipment as well).? HP/Agilent/Keysight probably is just as expensive these days, but the availability of parts and service information makes it possible for third party repair (such as ourselves).

Consider that in the 60s 70s and 80s computer simulation did not exist so long term predictions and studies were hard if not impossible to perform! Today you have computer simulation tools that are able to simulate virtually everything including decomposition
of materials under a variety of conditions making things a lot easier?

There is considerable lore regarding decomposing plastics and foams. Even today, we are learning about long term stability of these materials. The worst example I can think of is polyurethane. It looked very promising in the late
1960s, and was used in myriad products. Within fifteen years, that exuberence was crushed by costly disasters. A major cause for this was patent catfights and a shortcut in the formulation of the mass produced product. Another mega disaster? erupted in the
late 1970s and early 80s when the binder used in magnetic tape manufacture began to decompose. So far, this has not happened to data cassettes and floppy discs, but who knows?
