Hi In 75 I was playing with gun diodes and Klystrons at the age of 17 only test equipment where diode detectors on the end of a meter and an oscilloscope I had rebuilt after someone had used it for

Well, in the early 70's, to be able to do this at home, was fun and rewarding. From some heavy math to a final product. - Mike Mike B. Feher, N4FS 89 Arnold Blvd. Howell NJ 07731 848-245-9115 From:

Hi yes a lot of filter work can be verified using peak hold can be time consuming on a adjusting complicated filter Regards Paul _____ From: [email protected]

Hi Bruce I assume you are quoting the following I think what they are trying to sayis they REALLY want a network analyzer. SA +FG = S12 measurement Because I did not as most amateurs would not

In my early days of designing filters, I used to use a broadband noise generator with a 141T spectrum analyzer. Worked great in max hold after a few sweeps. Just had to make sure the total in-band

Hi Jim Yes filters that is exactly the thing I have used a spectrum analyser with a tracking filter for and they where all below 100 Mhz Regards Paul

How good do they have to be? How about the Mini-Circuits UNMP-5075? They have a ship from UK option. https://www.minicircuits.com/WebStore/dashboard.html?model=UNMP-5075%2B [email protected]> wrote:

Paul, The Midnight SNA was a neat little kit I built a couple of years ago mainly because I needed something to test vintage IF crystal filters with. As such its top end of 60 MHz was more than

Paul, Built-in tracking generators are rather nice.? When you are at a remote site in the winter in a blinding snow storm or somewhere else there really isn't time to be fudging around with multiple

It’s fairly simple. If they are truly 2/3AA cells pick up a couple from the millions of distributors on the web, specify ones with tabs, solder the two interconnecting tabs together and you have a

Hi John, if still available, I would show interest in this nice extender package. Would be glad to hear back from you. Thanks! Chris

Tam, no problem, thanks for the suggestion anyway. Looks like I'm going to have to wait for the CLIP docs. PS is dead-on, voltage is clean. Connectors reseatedseated. Unit is very clean. Amusingly,

Sorry Mate, I meant well. Wanted to make sure it does not get forgotten. Not my day today. Badly managed to hurt myself while shopping... Tam With best regards Tam HANNA Enjoy electronics? Join 15k7

Hi Jim interesting about you using the tracking generator daily Love to know how you use it in your daily job Regarding Street credibility I think we all have it if we have HP test equipment and I

Yes, the front-end gain calibration requires 5.000V. My fancy (and calibrated) voltage standard is good to 50 times better than that. :) The interpolator calibration does NOT require an input, in

I have used HP tracking analyzers at work almost daily for many years. Last year I acquired one surplus that needed minor repair for a stupid low price. I also own a Midnight SNA and NanoVNA. And a

I'd start with the obvious things. ?- check the PSU rails for voltage and ripple. ?- reseat connectors ?- just generally eyeball the relevant circuits

Hello, AFAIK, one of these tests requires a precision external voltage. Tam With best regards Tam HANNA Enjoy electronics? Join 15k7 other followers by visiting the Crazy Electronics Lab at
