Having bought ArtekManuals service manual, I now know that my target connectors go by the names of P611 and P612 on the 577, both of which are domiciled in the A1 Assembly at the bottom righthand side of the unit.

Sadly, I am a bit confused by all of this. The Tek service manual specifies P611 and P612 in the schematics, but their positions is not at all clarified in the parts locator. I printed out the manual, and am no wiser....even though I could find the connectors on the board by looking at it.

Re: Rockland 7530B Spectrum Analyzer plugin

 

Rockland Instruments has a good reputation for their test equipment but they were definitely pushing the technological state of the art in this 7000 series plugin and it shows in a bad way: It is a nightmare to troubleshoot! I have one of these and I have tried to troubleshoot but there are many substantial obstacles that must be overcome first. Here are some I remember:

1) It requires TWO flexible extenders since the plugin has to be several feet from the scope when troubleshooting because the seven computer cards are connected together by a backplane bus which in reality is a front-plane bus since it is located in the front of the plugin behind the front panel controls. This causes its own unique problems.

2) A front-plane bus that all seven computer cards plug into requires that you have a special 7530 extender card so that you can troubleshoot each of the seven cards outside of the card cage. Since each card being trouble-shooted (sp?) is sticking out of the rear of the plugin you need the two flexible extenders I mentioned above. I have never seen or heard that such a 7530 extender exists which means it is going to be something you have to make custom because the dimensions have to fit the card cage and have the correct contact spacing and contact count.

3) The plugin uses bit-slice computer chips. Apparently there were no microprocessors fast enough to run their FFT software algorithms so they had to use a complicated bit slice arrangement. I think there are actually two different bit slice computers inside the plugin. One handles the incoming data and one handles the formatting and display of the FFT. I don't know which one runs the FFT algorithm.

4) Aside from the front panel the entire thing is a self-contained specialized computer that digitizes the analog signal, processes it into a spectrum, and converts the digital data back to analog form to display on the CRT of a 7000 series scope. Whatever program it runs is inaccessible without a logic analyzer that works on that particular bit slice microprocessor instruction set. I don't think there ever was a logic analyzer for this chip set.

5) The plugin has so many TTL logic chips and bit-slice processor chips that are in it that it has to have its own switcher power supply to convert the high voltage power supplies of the mainframe down to the lower voltages and higher current needed by the logic chips. The switcher had to be contained in a thick sealed metal case (to prevent EMI from contaminating the incoming signal) so that may be even more difficult to troubleshoot.

6) There is no documentation, no schematics, no Theory of Operation, no Specifications.

7) The plugin covers a 0-100KHz range which makes it an audio-only spectrum analyzer. The 5L4 for the 5000 series Tek scopes covers the same range and the 5L4 has a built in Tracking Generator. The 7530B does not have a tracking generator and as far as I know Rockland did not make one.

8) Since this is an audio spectrum analyzer but the puzzling thing is it has a 1Meg input and does not have a more standard (for the audio industry) 600 ohm input as well.

Subject: [TekScopes] Rockland 7530B Spectrum Analyzer plugin

Around 20 years ago I bought a 7530B plugin. I only used it once or twice and then put it on the shelf where it sat until last week. That's when I pulled it out and put it in a 7603 only to find that it doesn't work, doesn't seem to even power up. Since I have no service information or extender cards for this unit I decided to sell it instead of trying to repair it, it's a nice clean unit, complete, nothing missing, the only significant cosmetic issue is the CAL knob on the front panel which is slightly damaged. I have it on Ebay, that's where you'll find it (seller name is "laser-artistry").

For sale 7103 working with plug-ins

Artekmedia <manuals@...>
 

I have a 7103 (1GHz , 3 slot version of the 7104) scope in working and good condition . Have only done a rudimentary checkouts, only minor problem noted is the brightness control is a bit flaky ( needs cleaning) . No significant screen burns that I saw. I bought this about 5 years ago for a project that never transpired and there is nothing in the foreseeable future that my 7904 cant handle, it has been powered up for a few hours each year with the brightness turned down so better it should come out of retirement and go live with someone who needs a scope of this caliber. It has been stored in a temperature controlled dry environment since I purchased it

Included are the following working plug-ins
7A29, 7A19 and a 7B92A

No probes
_
_*_Asking $350, _*( since this is pickup only all sales are preferred in cash, Checks 10 days in advance of pickup +2%, PayPal +10%)
_*
*__*Delivery*_
Pick Up only ( Riverview, FL , just south of Tampa)
I will deliver anywhere in the state of Florida for $.50/mile round trip. (Approx $90 Orlando, $215 Jacksonville, $270 Miami and $475 to Pensacola)

I will not ship this, it is too heavy, rare and valuable to trust to the likes of USPS, UPS or FEDEX. Please do not even ask

Contact me off list for pictures, serial numbers , other questions? It is unlikely I will attend the Orlando Hamcation in February, but driving over is about 1.5 hours to my location depending on the time of day

I'm sold! I just bought two. This is a higher feature design than I've seen anywhere else. And the price is very low considering what it is.
I can't tell you how many times I've blow fuses from having my current extender slide down in the slot and short out.

Thanks for pointing the way to these. Very nice work.

A new project saved the third 2445 that saved the other 2445 Who saved the 2465

David Az

A new project saved the third 2445 that saved the other 2445 Who saved the 2465

After I fixd my 2 oscilloscopes
2465
2445
And yet I am curious why there is the problem of the spot instead of the line
Which originated in Board A5.
Instead of opening the Oscilloscopes I have already fixed
It was easier to fix the third that was bought as an instrument for spare parts

He underwent extensive repair
I repaired the power supply
Power supply has undergone extensive renovation
And works perfectly all the voltages are accurate.

After that there was a problem in the voltage circuit A9
Unstable display. A huge spot smeared on the screen that covered half a screen.
I dismantled the CRT and washed it with soap
Then I cookd in the oven for 10 hours at 80 degrees.
I also disassembled the A1 board and repaired the faulty electrolyte capacitors
220UF
100UF
22UF
1000P
Now the 2445 III is in perfectly normal condition except for the dot problem instead of line A5 board.
The main suspect is the IC 4051
2408
2418
The 4051 I ordered arrived a few days ago
Only a placement problem because the new versions are in SMD
With the adapter
Wide
I have to be creative.
It remains to be seen whether this is really the problem.

The absurdity I started from one oscilloscope 2465
Which went up in flames.
I purchased 2445 two for fixing the 2465
I fixed the other one and did a painting project on it too.
And now I repaired the third one that was with full of problems
Just check for a hypothesis of a malfunction in the A5 board.
I'll update later ;)

Re: Transistor Cross Reference

Dave Casey
 

The Tek cross reference shows the 151-0062-00 to be a GA1392. I know that
in some applications, such as the 3B1 and 3B3 plug-ins, a product
modification (050-0581-00) was issued to replace the -0062 with a -0224
(2N3904).

THS730A, 720A Channel 1 issue

Erik Hultine
 

On both of these Chan 1 only passes the DC portion of the input. Connecting Chan 1 to the built-in compensation reference I get a 2.5 Vdc trace (which is the DC component of the 5Vpp square wave).
Chan 2 works fine on both. Both pass all self tests and SPC. The probe is good.
Can this be a cal issue? I have the service manual and schematics and plenty of tools/instruments, just wanted any insights before diving in.
