Tektronix 540 Scope

Thomas Dodge <camryguy83@...>
 

I have a Tektronix 540 Scope that I am trying to fix. When I turn it on, I cannot get a trace. I have the manual, and I am thinking that the power supply might have an issue. I would appreciate any feedback. I love Tektronix, and I always have. Thanks.

The Euro is equal everywhere, but what it buys, and
how much you get paid for your work are rather dependent
on where you are.

With Greece being part of the EU monetary union, the Euro is their currency and it's Euros they're looking for primarily but lots of dollars will do nicely as well I guess.

My experience with QService is all positive.

Re: 2454B 400MHz gives just about 300 MHz BW

Mike Czuhajewski
 

Thanks for all the commentary about the unscrupulous eBay dealer. I've run across a few test equipment sellers like that at hamfests and swapmeets over the decades. (And lots of honest ones, too.)

Although I haven't seen him for several years, there was also a refreshingly honest one. He told me that he buys the stuff surplus in bulk for pennies on the pound, has no idea what it is or how it works, or if it works, sells it "as is" at very good prices, and does a brisk business. (He also made that clear to all buyers.)

I'm hardly a "power user" of scopes at present, and haven't even turned on my 465B in months. But sooner or later I'll want to replace it or add to my test equipment collection and it's good to know about people to avoid like the plague.

(Thanks also for the commentary about how some folks game the eBay feedback system!)

Actually, when he offered that up to me, he wanted $900 something
to give me a "congenital" 2465B. He didn't suggest that he would
take my faux 2465B back, as I recall.

Actually, this is exactly what he said:

----------------------------------------
I feel no guilt over what I did, just the opposite - pride ! If you'd
like to retest the performance of your upgraded 2445B or reminted 2465B, all
you have to do is send it to me for calibration, for $150 (it has been a
while). If you'd like another 2465B (congenitally born that way, or later made
into), I can sell you one for $920, and I will even give you a choice if
it means that much to you. Thanks,

I have had all of the same discussions with Alex S. in the
past. He made all of the same arguments. He seemed well
practiced. I told him back then that if he had just disclosed
what he was doing, he would be a super star in the tekscopes
community, instead of a scoundrel.

He admitted to me by email, that he defrauded Test Equipment
Services Today (T.E.S.T), who then unintentionally, I am sure,
defrauded the Federal Government. He told me that he was in no
way responsible for that, as it was T.E.S.T. that sold his work
to the Fed's. I have an email into T.E.S.T., to see if they see
things that way.

There is no statute of limits on defrauding the US federal
government. They can come for you at anytime, usually at 3am
while you sleep.

One of my customers, after calming down from his discovery that
he had a faux 2465B, asked me to see if I could do something to
make his scope better. Since I had one too, though mine came
from a scrap pile, I gave it a try.

I added all of the trimmer pots that were missing from the 2445B
and through a combination of their use, and some creative tuning of
the transient response, I can get the full bandwidth expected of a
2465B... complete with a sub 1ns risetime. The leading edge of a
super fast risetime square wave is a little rattier than I like,
but then the 2465B is inconsistent in that area too...

The rattiness doesn't show for anything but a super fast risetime
square wave, and most people don't have a source of such a signal.

If your scope needs calibration, a battery, or a new NVRAM, you might
want to consider putting me to work.

If you would prefer to do this yourself, I can put together a list
of the required modifications... the tuning technique is something
you will have to learn for yourself.

Re: Best website for buying old tek replacement parts?

I know my memory is awful, but didn't Deane die back
in September 2015?

As to Mr/Ms Highpower's complaint. Well, what can I say?

It is near to impossible for anyone to be able to make a
living, let alone a decent living, in the US or Canada
serving the tekscopes community.

About the only way to do it would be to sell things that
everyone in the tekscopes community needs that aren't a
part of any scope, like candy, beer, toilet paper, and soap.

Qservice is in Greece, where the economy is so fcked up that
a single US dollar is something worthy of really pursuing.

Here in the US, the dollar is so inflated that I have seen
people walk on by when one is laying out on the sidewalk.

Re: Best website for buying old tek replacement parts?

 

Hi Highpower,

It is easy to be spoiled by dealing with large distributors (Amazon for example) where you can expect their inventory to be accurate up to the minute. This is not the case for obsolete parts for the second hand or surplus scopes we are using. Sphere has been a valuable resource over the years, even more so since Deane Kidd passed away 5 years ago. Resources like Sphere are drying up. It may seem hard to appreciate them now but none of them will be here for much longer. Walter and Susan are retiring and slowly winding down their business. They have served us well and we owe them our thanks. Please forgive them for an occasional incorrect entry in their database.

When my 577 curve tracer failed recently and I needed a High Voltage Transformer I only found one available anywhere in the world (and I have a lot of Tektronix resources). If that one was not available to me I would have been forced to look for a used part by hunting for a particular serial number range of a particular scope model on eBay and hoping one would show up at a reasonable cost ($50 to $75 plus shipping was starting to sound very reasonable). Even then there would be no guarantees it would work.

I've been to Sphere many times and I do not envy Walter and Susan one bit. Sphere has tens of thousands of Tek parts and most are in carefully labeled boxes. The task of finding any one thing must be exhausting. For someone to ask for a $0.10 transistor involves so many hidden costs like purchasing, incoming inspection, sorting, labeling, locating space for it, developing a database, adding it to the database, updating the database as quantities are sold, and then when it is time to retire, getting rid of it all.

And all of this has to be done by just two people. I'm glad I had them as a resource for so many years. Qservice is another excellent resource you should take advantage while you can. The truth is that with the passing of Deane Kidd we can no longer count on a supply of spare parts. Soon there will be no more spare parts.

Avoiding ebay might work, but my faux 2465B came to me
straight from a DOD scrap pile. The DOD bought it as a
2465B from Test Equipment Solutions Today (T.E.S.T.) A
fairly well known women owned test equipment dealer. I
mention women owned because that is a code word for counts
on getting preferential treatment from the US Government.

So, this guy doesn't only do ebay.

In one of his letters to me, he claims to have bought original
2465B labels from tektronix in batches of 50 at a time... doing
so until tektronix eventually ran out of labels.

as lots at tech companies and government auctions. Does not mean that I do
not get burned occasionally. It takes time and effort to thoroughly
checkout received equipment claimed to be fully functional, but for the
most part, I can do a quick check out of the item upon receipt to the
extent that I will be using it. This situation with the 2465s would be
difficult to catch without knowing someone's previous experience with an
