Watching these videos has sparked my interest in my 3457A and raised some questions. As for calibration, the Agilent website lists a per incident calibration at $204.22 and an End of Support date of

I have used a product from Anders Products called Wire Glue. Not an inspiring name, but works very well. It is non conductive until it cures. Very low resistance and dries to a dark neutral grey

Here's another product --> http://www.sandman.com/rubberb.html <http://www.sandman.com/rubberb.html> but a bit more pricy! Gary know how it works, and how it dries, for a totally different use.

Bryce, I actually use a Softrock Ensemble II SDR for shortwave. It has the added advantage of being able to precisely lock on to the WWV stations and check the accuracy of my frequency counter. It

Thanks Dave, I actually have watched those videos. Bit drawn out like most of his videos..but still good. Too much detail is not always a bad thing. As for the 3457A, if it works I plan on getting it

Based on warranty statements of other HP BWO gear, it looks like filament failure is the primary cause, maybe preceded by instability of some type. The Stewart BWOs had a warranted filament life of 18

Interesting stuff. ?I have not used it but I too would like to know how it works, and how it dries, for a totally different use. ? How black is it when it is dry? ?I am curious if it would make a

Dan, If you weren't on the other side of the US from me, I'd be glad to take it. Bill

I Can't remember where, but I've seen repair kits for kits for those types of keyboard switches. Bill HIgdon

There was one on Ebay. I bought it. It has a shunt impedance of 50 ohms and a series impedance of zero ohms....Looks just like a 11048C to me...I don't understand. Dan in Chandler,

I have similar stuff in high-performance Mil stuff. The SMAs were all overpainted with silver bearing paint, and the entire box was lined with microwave absorbing black foam sheet. This was in a 2 to

Hi Dan. Well It's like I said memory isn't what it used to be. That unit does not fit my needs. I'm looking for something that covers from about 500 kHz to 250 MHz and won't cost me three arms and

The recent discussion mentioning "conductive foam" reminded me of a serious potential problem to watch for. I had an old Gigatronics 600 series sweeper in which they had used pieces of conductive

Hello Chuck, That's good news. I've seen various of these units with that message and it's always been an issue with the backup cell (or the test jumper)....! Best regards, Ron Wilkinson mi-Biz

Thanks for the advice Karl; I'll give it a try. Gary

I'd think pretty good. Anyway, this might interest you - a review of the 3457A. Part 1 seems pretty good - I've not seen part 2, but I'm going to take a

I used an Sa612 mixer chip feeding a LM3089 into a 386 audio amp chip. That setup is cheap and can be configured to give am and fm but no ssb. The best solution is to find a used AOR 8000 wide range

Conductive foam:? I have found the torque on the mounting screws needs to be near perfectly?equal for these to work. Lots of trial and error :-) As for the switch contacts, I have found it is a
