[Tek2440] Java GUI feedback requested. #photo-notice

Jan de Jongh
 

Dear Tekkers,

Over the past two months or so, I've been working on a [Java] GUI for my Tek2440 accessed through a ProLogix GPIB-ETH . Since I still do not know all the Tek2440's features that well, I'm asking this group for feedback on the GUI I constructed so far. A screenshot is in Photos (don't know how to embed/refer; tips WELCOME!). In the figure, all gray rectangles pop up a dialog for controlling the particular group settings.

Main questions are:
- Should specific functions/settings now embedded in dialogs be available in the main application window?
- Should functions be moved into dialogs?

Needless to say, I cannot make all settings available on 900p/1080p, sp I have to make choices...

Thanks for your response; FYI, the code is on https://github.com/jandejongh/jinstrument although I'm planning on forking a Tek2440 specific project.

BR

Re: Difference between a 475 and a 475A

John Gord
 

Jeff,
My unresearched recollection is that the 475A was basically the same as the 475, but adjusted for higher bandwidth but perhaps slightly inferior pulse response. The 475A lacked the 2mV/div vertical setting.
--John Gord


Difference between a 475 and a 475A

 

I have a 475 that belonged to my father, manufactured in late 1974, that I have a sentimental attachment to and would like to keep running. To this end I have purchased several "for parts" scopes on eBay, both 475s and 475As, because many of the mechanical parts appear to be completely interchangeable. I had terrible luck with the first parts scope: while it is in terrible cosmetic condition (busted knobs, spattered with something that does not wash off with soap and water or with isopropyl alcohol), it appears to be operating flawlessly. Next I received a 475A which appears to be a much better donor candidate as it appears to be quite sick.

I have done thorough inspections of both scopes when I received them, and I noticed something odd: the sweep board of the first parts scope (475) does NOT look like the sweep board on my father's 475, but it DOES look almost identical to the sweep board on the 475A, which makes me wonder if it might not actually be a 475A with the faceplate of a 475.

I pulled down the schematics for both the 475 and the 475A and compared their vertical amplifier sections, on the basis that a higher bandwidth scope would require upgrades to the vertical amplifiers. I also made a thorough assay of the part numbers for the PCBs and custom ICs in all three scopes, hoping to find some definitive evidence for which scopes were 475s and which were 475As. Sadly, aside from the layout of the sweep board, I have not found anything conclusive.

The collected information on the three scopes follows:

475, vintage 1974
vertical amp board PN 670-224-01 or GH-2780-01
- switch IC PN 155-0091
- 1st pre-amp IC PN 155-0085-01
- 2nd pre-amp IC PN 434-0078-02 / 437-0078-02
main board PN 670-2239-04 or GE-2779-01
trigger board PN 670-2241-03 or GH-2781-01
- sweep IC PN 155-0059-01
- trigger ICs PN 155-0032-01
sweep board PN 670-2244 or GI-2784-05

475/475A? vintage 1976
vertical amp board PN 670-2240-08 or GH-2780-01
- switch IC PN 155-0091-00
- 1st pre-amp IC PN 155-0085-10
- 2nd pre-amp IC PN 019-0078-10 / 936-0078-10
main board PN 670-2239 or GE-2779-01
trigger board PN 670-2241-03 or GE-2781-02
- sweep IC PN 155-0049-02
- trigger ICs PN 155-0217-00
sweep board PN ? or GD-3980-02

475A, vintage 1978
vertical amp board PN 670-2240 or GH-2780-01
- switch IC PN 155-0091-00
- 1st pre-amp IC PN 155-0085-01
- 2nd pre-amp IC PN 813-0098-03
main board PN 670-2239 or GF-2779-01
trigger board PN 670-2241-02 or GA-2781-02
- sweep IC PN 155-0049-02
- trigger IC PN 155-0032-01
sweep board PN ? GD-3990-02

There are also differences between the parts in the 3rd pre-amp, but I'm not sure what to make of them because the physical circuit on the boards differs significantly from the schematics and parts lists.

Are the 475 and 475A really just the same scope with a marketing upgrade? I know that Tek over-engineered their scopes, and that a 475 may well be able to handle signals up to (and beyond) 250 MHz, but I expected to find noticeable upgrades to the vertical amplifiers. I suppose that it's possible that my father's scope was upgraded in the field (that is, by Tek field service personnel, not by my father), but other such modifications have been accompanied by option indicators, and there are not such indicators in my father's scope.

Have I been looking in the wrong place for the modifications that would distinguish a 475 from a 475A?

Are there, in fact, no such modifications, and the 475A was merely a marketing upgrade?

How would I be able to tell if a scope had had its front panel swapped with another scope? Is the scope serial number recorded anywhere other than on the plate at the bottom of the front panel?

Thanks,

Jeff Dutky

Subject: [TekScopes] Tektronix Technical Briefs (or whatever they're called in 2020)

For several decades, Tektronix has released these "Technical Briefs:" a.k.a. Technical Documents, Application Notes, and possibly other names.
Is there a single point(s) of curation for them?







LAST CALL for Peter Keller's Book and Current Orders I have

 

This is a last call for Peter Keller's fabulous book. I will accept orders
until Friday evening my time. At present I have orders for 75 books.
At that time I will publish the final list of people I have received an
order from and I will explain how to make payment.
Below are the people who have been placed on Peter's book order. Please
confirm your name is on this list.

If you have missed all of the excitement here is a summary
Pete Keller (from Tektronix) is prolific writer about cathode ray tubes and
many other kinds of display technologies.
He published a very detailed book on the subject in 1991 which I highly
recommend. The book title is:
"The Cathode Ray Tube, Technology, History, and Applications", Peter A.
Keller. 320 p.
ISBN 0-9631559-0-3;
TK7871.73.K46;
621.3815'42-DC20

I paid $70 for my copy years ago when I bought it from Peter. There is a
copy of his book currently on eBay listed for $650!!!
Peter's book is still available in hard cover and he has copies of it to
sell to us.
Because of recent interest in it from TekScopes members I went out on a limb
and asked Peter if a discount would be available for our members if we
bought enough books to make it worth his while and if I did all the work for
him.
He agreed and offered our members a huge discount. The cost will be $30 +
shipping.
I am hoping I can even get him to autograph each copy.
I promised Peter I would keep his effort to an absolute minimum by
collecting the names and addresses, payments which I would send to him in
one lump sum; then when he ships all the books to me I will mail each book
for him.

The cost for a book going anywhere in the US is $30 + $4 Media Rate Postage
+ $3 for supplies and my time. The total will be $37.00.
The cost for orders overseas will be $30 + approximately $35 for Flat Rate
International Priority Mail (this includes tracking).

If you want a copy of Peter's book send your mailing address to me OFF-LIST
at dennis at ridesoft dot com. INCLUDE YOUR ADDRESS.

These are the orders I have as of 2:15PM (UTC-08:00) Coordinated Universal
Time-08.
If your name is not on this list then I missed your order (my apologies) so
resend it with your address.

Re: Tektronix Technical Briefs (or whatever they're called in 2020)

 

Hi Roy,
In the 1970s and 1980s they were known generically as Application Notes. Tek changed their numbering system several times for various reasons.
* In some cases they were published by the group that created the instruments (Spectrum Analyzer articles came from that group for instance).
* In some cases they were created by the marketing person for a particular product line (like the TM500 instruments).
* In some cases they were created by a separate division of Tek (like the TV Instruments, or Laboratory Scopes divisions).
* In some cases they were articles written for trade publications which Tek had permission to reprint.
* Some excellent articles were written for Tek Periodicals such as Service Scope, Handshake, etc.
As if that wasn't confusing enough the same Application Notes were printed with different numbering systems when Tek tried to place all of these things under one group within the company.

So to answer your question: There is no rhyme or reason for how Tek did it.

Dennis,
Uithoorn and Amsterdam may be combined in one shipment to Uithoorn. The places
are close together and I (in Uithoorn) will take care of it, once I know the

Hi Dennis,
The person living in Amsterdam has contacted me, I've met him before. We have agreed that you may send both his (Amsterdam) and my (Uithoorn) book to me.
Payment arrangements will be made separately.

TDS 784A / 754A WARNING-ERROR MESSAGE

Gif Sim
 

good morning to the whole group

I have a tds754a upgraded to tds784a by configuring the resistors and removing the capacitors in the acquisition card

the acquisition card is 671-3953-00
the microp board is 679-3488-00
the serial is b010976
the memory board is 1M

all electrolytic capacitors have been replaced and the oscilloscope works perfectly
the ds1486 was replaced with a working battery
It was originally mounted a DS1650y that has been replaced with a DS1250y-100 with a working battery

when I connect the tek FAS software with gpib and start the first calibration phases
in the error log I get some truncated warning messages:

"WARNING: 600 remote nv memory a ...."

the calibration then proceeds smoothly (but I haven't finished it yet)
what does this warning message mean and what can be the cause?
thanks to everyone who can be of help

A greeting

Simon


Re: Tektronix 7D13 and 7A42 wanted

 

Hi Ed and Dan,
I'll toss the battery and remove the jumper in mine also.

Hi Dennis,

I didn't realize earlier your question "What did you use for a battery?" was to me. There is no battery. For something like this, it's simple enough to set up as needed, for occasional use. Having it remember is a nice convenience, but not worth the trouble and leakage risk. All I did was check it out after enough burn-in, and I removed the BE jumper as Dan suggested. It's running right now for one last time before mothballing.

Re: Q122/222 Jfet J300 subs for 2215A scope ?

Ed Breya
 

Oops - I meant to say Vds here, not Vgs:

The Vds should be fairly constant since the required output excursion is only about +/-100 mV.

Ed


Re: Q122/222 Jfet J300 subs for 2215A scope ?

Ed Breya
 

Yup, I see it. I finally looked at the schematic for the 2215A. Looks like the quiescent drain current should be around 11 mA, and the source at Vbe.I'm looking at the J310/J309 data sheet here:

https://www.mouser.com/datasheet/2/308/J309-D-109346.pdf

If I'm interpreting Fig. 1 properly, the lower curve set is for the J309, and the Id is about right for Vgs= -Vbe. The upper curves for the J310 are about 3 X higher - too far out there for the nominal circuit conditions, although Q15 could probably pull it hard enough to DC balance (but things would start getting weird). The JFET runs with Vds about 8V, so pretty close to the 10V used in the specs. The Vgs should be fairly constant since the required output excursion is only about +/-100 mV.

This circuit reminds me of the ones in all the other 2200 series, and may be essentially exactly the same. More info may be discerned by looking at those others to see what JFETs were used. The 2N5486 keeps sticking in my brain.
