Moderated Re: Recommendation for an "up to 1GHz" generator + sweeper
Not sure about the newer IFR/aeroflex stuff but the marconi stuff I worked on back at tucker was horrible in terms of signal quality and reliability

Some of the user interfaces of the R&S and Agilent/Keysight sig gens aren't great, either.Jim Ford?Sent from my T-Mobile 4G LTE Device

To beat a dead horse, my standard answer when the question of why they did it that way comes up is, "It was cheaper."Jim Ford?Sent from my T-Mobile 4G LTE Device

Radu At first you want to sweep, and none of those, except for 8662A and 8643A, can sweep. Regards, Ruben

Have you looked at the Marconi/IFR/Aeroflex 2023/2024/2025 sig gens. They have the ability to sweep, we use them here at work. Biggest knock is the menu system.......

Re: 8903B Gooey Crystal
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

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

Re: 8903B Gooey Crystal
And the product was never designed for a 30+ year lifespan to start with. So whining about "suits" has no place here anyway. Wilko (who has been exposed to the "suits" problem, thank you very much

Re: 8903B Gooey Crystal
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

Re: 8903B Gooey Crystal
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

Re: 8903B Gooey Crystal
I've had good results cleaning off bad foam, with 'Fast Orange' automotive hand cleaner. I put a thin layer on the mess and lay it out in the sun for a while, then hose it off.

Re: 8903B Gooey Crystal
I am not a plastics guy but I am sure foam has a specifjed life expectancy , I think that agilent like most other manufacturer put a service life of probably 10 years on their products and picked a

Re: 8903B Gooey Crystal
Sorry guys, but this cannot be blamed on "suits". Products of this vintage and quality class were not cost driven. The simple explanation is that HP rarely tested foam products to the degree they

actually it shouldnt take long for the YIG to heat up , the heater in a YTO actually is a small thermistor mounted on the BeO rod that holds the YIG Sphere , the thermistor has a low DC resistance as
