Re: PYRAMID CALIBRATOR AND TESTER FOR TEKTRONIX OSCILLOSCOPES

 

Nice build cabinet, could be a handy tool. But strange he uses 75 Ohm bnc connectors for a 50 Ohm output. ?Also rather expensive

For that price you can make a very nice one yourself.?

Just a uProcessor to generate some squares, or maybe a Xtal and something like a 4060, for higher frequency and trigger test you add the cute little Jim williams pulser. Williams also has a schematic of a very simple timemark generator ( i do not the app note from the top of my head)

a TL431 or LT1027, a good opamp and some 1% resistors and a switch to make some accurate voltages ( a scope is 2 to 3% so this will be close enough)?
It does not matter if frequency is not in all exact steps. For a test its OK to see if the ranges still work. I think for real calibrations this is will not be enough , it only goes up to 1uS/div and for buy-checks it can do more than needed.?

If I needed one I would use this as a base :?
the Tek evaluation board we reverse engineered around 2 or 3 years ago here on the group.
And add this :? if you want use a switch and resistors to make fixed frequencies. 500 ps Tr and 16-160 MHz in 3 ranges so if you use 5 resistors and two switches you have 15 frequencys.
Total cost maybe 10 dollar in parts, 10 bucks for a nice cabinet so you can spend 130 dollar for another scope ;-)

AFAIK, the specific heat capacity of aluminium is much larger than that of steel, but this seems somewhat extreme...

Re: 2465 with broken intensity on ebay

 

If the seller is prepared to open the scope's cover, you can try this:
1. Ask seller if take a close picture of the grid bias potentiometer to help give you an idea where the grid bias pot is set. Not really necessary but useful to have.?
2. Have him tweet the grid bias either direction ever??so slightly and adjust intensity after?each tweet. If intensity control is effective, then maybe CRT is ok and you can fix the scope.?

You need to realign grid bias pot later. Adjusting the bias shift?the operating point so that intensity control
Can affect the electron beam.?

Re: 7L14 - no 1st LO output

Chris,
Your question was clear, both David DG and I didn't read it well.

This is one ref. to a Freescale (-Motorola) part with just a few specs:


Here you can see that the mil-designated Freescale part is considered at least in some way compatible with Tek's part and DST1010 (and some others).

I guess you've seen it already.

Absolutely correct - the original is a DTS1010, but again, thanks for the pointer to the datasheet for that part.
My interest is in trying to get information about the part actually installed as the YIG main coil driver in my (failed) 7L14.
I just want to know if it is supposed to be better/different/was a factory installed replacement etc.
during the 7L14 lifetime (according to my Manual) this board (YIG driver) went theough three iterations (suffix -01 through -03) yet mine is a suffix -00, confusing or what?
Really my interest is in trying to get some data on this Motorola part, to add perspective to this issue, but?I have a correct replacement, which I will use & see what happens!

Re: Tektronix 2465 capacitors etc.

 

Chris -

I have a spreadsheet with parts for refreshing the 2465a LVPS along with Mouser part numbers. This has worked well for my scope. After reading the Condoraudio piece and looking at this list you can decide what you want to do. You can grab the spreadsheet 2465LVPS_ReCap.xls from

Hello all,
I'll try and keep this short. When it comes to electronics I'm somewhat a newb, but not entirely. I've always been interested in it, and I've recently purchased a scope - the tek 2465 300Mhz unit. Spent some time getting familiar with it, playing around in XY mode, and then used it for some diagnostics with some inductive sensors I was having an issue with. Just when I was getting ready to pack it up from verifying the sensors the scope went a bit goofy. The display at the bottom appeared to be "compressed" to a a central blur (I could change it's intensity with the readout intensity) and my traces were a short line near the center of the screen. I powered the scope off, waited a few seconds and then powered it back on, and it now powers on, lights up all the LED's, and I get a super bright --- display at the center of the screen (unaffected by intensity adjustments etc).

So, as typical I pulled the cover and did an initial once-over. I found that on the main power supply board by the mains that 2 of the capacitors look rough (one with the outer shell opened up). If you reference this pdf regarding a 2465B, the 2nd image of the A2 PCB has the very capacitors circles in red. The lower most one in the image is the one that looks like it may have blown. I haven't pulled the board out of the scope to get a better view of it yet. The rest of the capacitors on the board are the green and brown mix as the image in the PDF shows, which leads me to believe they're still the original capacitors in the unit.

Now in researching and reading about these scopes before I purchased one, I had read that the capacitors were a common issue in them. I have no worries about un-soldering components and soldering new ones in as I've done it numerous times to revive other old equipment. (And I've read about the need to cool these scopes with a fan if you operate them with the cover off)

So sorry to drag this out, so I'll try to make this quick. For those in the know about these scopes, is there a listing/BOM for what capacitors should be purchased and replaced?

Does the 2465B use the same values/locations on their boards that I can just follow the PDF I linked?

Does my issue sound like something that the capacitors could be causing? Or is it likely more involved?

I'd be happy to provide images or video as requested if it will help.

A huge thank you for taking the time to read and/or respond!

Hello, Folks:

Amongst other Tek gear I own, I have the subject L-C Meter, the Model 130.

Although it is all complete, the meter "case" has been damaged (although
the meter movement is OK).

The front cover has had a big chunk broken out of the top.

Does anyone here have a spare meter they would sell for a reasonable

I would like to get this unit working as soon as I can.

You should be able to get large boxes at the local U-Haul dealer.

People who rent moving trucks need to pack their stuff.



They also have corner protectors:

X8-?id=8220



Also:

ors?id=4008



I think the best way to pack a scope is a box-in-a-box approach, with
peanuts or foam between the boxes.

I have a 465 that, except for a blown HV multiplier (part 152-0552-00) ,
works fine. The problem started while I was using it, so I know it works
fine.



There is no display on the CRT and I've traced the problem to the -2450
supply. Following the troubleshooting procedures, I disconnected the anode
lead and the dummy resistor in the HV supply and the -2450 came up. The
manual's suggestion at that point is to replace the HV multiplier.



I was planning on selling this scope anyway so I'm hoping that someone on
this list:



1. Wants a 465 that only needs a HV multiplier



2. Has the part I need and wants to sell it (part 152-0552-00)

Chris

Is there any chance of getting a schematic of the flash circuit?
I have an old C5B and plan to use it with a modern digital camera on my Tek

The flash lights up the phosphor to backlight the grid on the 8505A which
does not have scale illumination. My email should show up to members.

I am looking at the schematic for the C5C scope camera (Diagram #1 SHUTTER
CONTROL) in the manual and as near as I can tell the 6V battery pack is
never disconnected from the camera electronics which would drain the
battery
eventually. The only switch on the unit is the shutter timer switch which
has two positions: TIMED SHUTTER and SPRING RETURN. In the neutral center
position the switch leaves part of a gate ungrounded, but power is still
flowing all the time from the battery across two 100uF caps (for energy
storage) to most of the rest of the circuit.



My DM501A confirms there is about 50uA or less (it's getting down to the
residual capability of the DM501A) flowing all the time once the
electrolytics are fully charged again after the shutter solenoid has been
pulsed which discharges them.

Hello, Peter--

As an alternative, you might want to investigate using
ultraviolet- emitting LEDs, which you could arrange in a frame that fits
around the CRT's outer edges and illuminates the CRT's face.

You could bypass the original flash circuitry and devise a one-shot
multivibrator (e.g., a 555 timer) to pulse the LEDs.

I tried the UV LEDs first. They didn't work - probably because they aren't
very far into the UV. They are pretty long wave UV - more purple than
anything. In fact, every kind of LED I tried didn't work.

The most stubborn CRT of all is the one on the 577 D1 Storage Curve Tracer I
have. Absolutely nothing I own would excite that phosphor. I tried a mineral
lamp, my 1970s UV Prom Eraser, fluorescent lamps, etc.

All the other CRTs in my lab glow warmly with different colors when I turn
off the overhead fluorescent lights for the night except for that CRT which
is just dark and cold. Then Stan Griffiths told me about the C5 flash unit
which was specifically designed for the 5000 series of CRTs (the 577 uses
the display unit from the 5000 series). That flash excites the 577 CRT like
crazy. I'm not sure why, but it is the only thing I have come across that
wakes it up.

Have you tried ArtekMedia for the manual?

Dennis

<mailto:paul@...?subject=Re%3A%20TM%20module%20pull%20tab%20needed
"Paul Amaranth" amaranthp

I recently picked up an SG503 from a Tek ebay chipxs auction.

I was a bit annoyed since the item sent did not match the
item pictured. It was a lot dirtier and, more importantly,
it was missing the pull tab. Well, it was shipped in a
Tektronix box, that has to count for something. I'm
still waiting for a response from them.

Does anyone have a spare pull tab from a dead TM module?

Alternatively, does anyone have a dead TM module they want
to sell cheap? (but it does need the pull tab)

thanks

I think the easiest test would be to measure the z-axis signal before
the DC restorer but I would not call that simple.

No, and you should also consider that if you want this scope, you
don't really want the seller turning it on any more, and possibly
burning the phosphor.

I think I will not try the spray foam in a box idea- as Rob relates, it
can be a bloody mess.<< <

Certainly was for me, however; given my one off and ill prepared (and
un-documented) attempt coupled with the consequences of a successful
methodology. Well, we might want to leave the possibility more open (or at
least give it a status of "the jury is out") as there were also some
reported success. It may be something dependent on brand, method, temp, etc.
and I hate to throw it out based on my input.

Concisely if we (as a group) can find a successful method involving spray
foam it is way preferable to peanuts and could land one in as close to
original packaging as possible..

Well at least 2 cents worth that wasn't asked for. sorry.hopefully doesn't
sound argumentative, it isn't meant to..

Hopefully helpful though or at least worth the bandwidth.

Thanks everyone for your ideas!

I think I will not try the spray foam in a box idea- as Rob relates, it can
be a bloody mess.

The boxes at appliance shops (when you can get them) are often way
oversized. In the past, for padding and in order to fill space in an over
large box I have used other smaller boxes (of which I have plenty) and even
empty 1 liter plastic bottles (from soft drinks, juice, etc)- as long as you
screw the caps on they make very good filler that is stiff yet cushioning
but can't be crushed. Also, I'll put peanuts in bags, and use those bags as
filler, rather than use just the loose peanuts.

I'll look into your suggestions/ sources.

Thanks!

Keith

That guy sold me a manual for a RLC bridge once, with exactly the schematic
page missing where the fault is located.
He didn't care when I pointed it out.

I was not impressed, but I guess when you need that manual you'd buy it
from the devil and be glad.

Hello, Folks:

Amongst other Tek gear I own, I have the subject L-C Meter, the Model 130.

Although it is all complete, the meter "case" has been damaged (although
the meter movement is OK).

The front cover has had a big chunk broken out of the top.

Does anyone here have a spare meter they would sell for a reasonable
sum?

I would like to get this unit working as soon as I can.

Thanks,

Ken Gordon

FWIW, my LC meter arrived with a meter case that was broken in a dozen
pieces due to exceptionally dreadful packaging. Fortunately for me, I had
earlier bought on eBay a boxed new-old-stock 130LC Meter meter. So the fix
was easy. But I wouldn't hold your breath waiting for one to turn up like
that - I was just lucky.

I can't think of one off hand but would there be any other Tektronix
gear that used a similar style meter that you might be able to salvage
the bezel from. Alternatively, would Tektronix have made the meter "in
house" or is it an off the shelf meter that might be found elsewhere.

Hi
I see that you have worked on the 2715 Spectrum Analyzer. I have post
previously a request, that you might be in place to help me solve it.
I want to find the Cable TV RF Measurement Software for the Tek 2714/2715
Spectrum analyzers. Is it still available, or is it possible to get it
somehow?
Or suggestions where to look for it? I have got a 2715 and would like to
have that software in my lab PC.
I think it should be similar (or even the same) as is for the RFM151 Signal
Scout analyzer, but not sure also about it if it can be found. as these have
been transfered to another company according to Tek site. However at the new
owners there is not even a single clue about RFM150/151 equipments!! !
However for me even for that one will be helpfull as I also just got one of
them. :)
Can you help on finding these, if possible please?

Best regards & thanks in advance
Sotiris Pdmtr

I am helping a customer locate a schematic for a later serial 2710
Analyzer power supply. His serial number is B033837. I have a later 2710
manual 070-6024-01 with change pages up through serial B021322. But the
later power supply is not covered in there. The latest supply A15 in my
manual is part #621-0042-00. His A15 carries a part number 671-1599-00 ...
If you have any info on the later supply schematic and parts list
ArtekManuals will give you a free PDF of your choice for the favor of the
loan of the pages to scan. IT is possible that this supply is used in other
27xx ananlyzers as well, but I only have schematics for the 2710 and 2755 at
the moment

You should be able to get large boxes at the local U-Haul dealer.
People who rent moving trucks need to pack their stuff.

They also have corner protectors: ? http://www.uhaul.com/MovingSupplies/Protective-stuff/Bubble-Corners-16-EA-8-X8-?id=8220

I think the best way to pack a scope is a box-in-a-box approach, with peanuts or foam between the boxes.

Bob,

Thank you for checking on that. Someone else offered me an unknown condition multiplier for cheap, so I accepted.

If that doesn't pan out, I may take you up on your offer, if it's not too late!

Thanks,
Chris

I checked the manual and the 465B uses the same multiplier.?? So I could disassemble my parts unit and remove the multiplier.?? I have no idea whether it is good, and it will probably be a bit of work to remove it.

Let me know what you think.

I have a 465 that, except for a blown HV multiplier (part 152-0552-00) , works fine. The problem started while I was using it, so I know it works fine.



There is no display on the CRT and I've traced the problem to the -2450 supply. Following the troubleshooting procedures, I disconnected the anode lead and the dummy resistor in the HV supply and the -2450 came up. The manual's suggestion at that point is to replace the HV multiplier.



I was planning on selling this scope anyway so I'm hoping that someone on this list:



1. Wants a 465 that only needs a HV multiplier



2. Has the part I need and wants to sell it (part 152-0552-00)



Thanks,

Chris

Is there any chance of getting a schematic of the flash circuit?
I have an old C5B and plan to use it with a modern digital camera on my Tek 2467B 'scope and my HP 8505A Network analyzer.
The flash lights up the phosphor to backlight the grid on the 8505A which does not have scale illumination. My email should show up to members.

FOLLOWUP:

I switched to my DM5010 which can display down to units of nAmps! And it
appears the current eventually stabilizes around 2 or 3 nAmps which I would
assume is about the limit of the instrument. Pretty impressive instrument -
Tek bought the guts from Fluke, another (now) Danaher company. Presumably
the current goes to zero after the caps are fully charged which took about
30 minutes.



I still don't see how power to the electronics gets disconnected from the
battery. The only mention in the Theory of Operation about the batteries is
the paragraph that says "When new batteries are installed, the shutter may
cycle. The Low Frequency Oscillator also ensures that the shutter will be in
a closed position after new batteries are installed." Pg 3-2.

I am looking at the schematic for the C5C scope camera (Diagram #1 SHUTTER
CONTROL) in the manual and as near as I can tell the 6V battery pack is
never disconnected from the camera electronics which would drain the battery
eventually. The only switch on the unit is the shutter timer switch which
has two positions: TIMED SHUTTER and SPRING RETURN. In the neutral center
position the switch leaves part of a gate ungrounded, but power is still
flowing all the time from the battery across two 100uF caps (for energy
storage) to most of the rest of the circuit.



My DM501A confirms there is about 50uA or less (it's getting down to the
residual capability of the DM501A) flowing all the time once the
electrolytics are fully charged again after the shutter solenoid has been
pulsed which discharges them.



Dennis



PS I didn't see a PDF anywhere on the internet or in all the usual document
archives when I looked for one. Fortunately I happen to have an original
manual.

Hello, Peter--

As an alternative, you might want to investigate using
ultraviolet- emitting LEDs, which you could arrange in a frame that fits
around the CRT's outer edges and illuminates the CRT's face.

You could bypass the original flash circuitry and devise a one-shot
multivibrator (e.g., a 555 timer) to pulse the LEDs.

I tried the UV LEDs first. They didn't work - probably because they aren't
very far into the UV. They are pretty long wave UV - more purple than
anything. In fact, every kind of LED I tried didn't work.

The most stubborn CRT of all is the one on the 577 D1 Storage Curve Tracer I
have. Absolutely nothing I own would excite that phosphor. I tried a mineral
lamp, my 1970s UV Prom Eraser, fluorescent lamps, etc.

All the other CRTs in my lab glow warmly with different colors when I turn
off the overhead fluorescent lights for the night except for that CRT which
is just dark and cold. Then Stan Griffiths told me about the C5 flash unit
which was specifically designed for the 5000 series of CRTs (the 577 uses
the display unit from the 5000 series). That flash excites the 577 CRT like
crazy. I'm not sure why, but it is the only thing I have come across that
wakes it up.

Have you tried ArtekMedia for the manual?

TM module pull tab needed

I recently picked up an SG503 from a Tek ebay chipxs auction.

I was a bit annoyed since the item sent did not match the
item pictured. It was a lot dirtier and, more importantly,
it was missing the pull tab. Well, it was shipped in a
Tektronix box, that has to count for something. I'm
still waiting for a response from them.

Does anyone have a spare pull tab from a dead TM module?

Alternatively, does anyone have a dead TM module they want
to sell cheap? (but it does need the pull tab)

thanks

I think the easiest test would be to measure the z-axis signal before
the DC restorer but I would not call that simple.

OK, thanks. So there is a possibility.

Is there any simple test I could give to the seller which might differentiate between the two?

Thanks

Hi,

Just looking at a 2465 on ebay which has just come up. It seems like the
intensity is stuck on full brightness.

I'm just wondering whether this is likely to be an easy fix? I did some
googling and found someone suggesting that a similar problem might be
caused by a faulty hybrid.

Thanks

No, and you should also consider that if you want this scope, you
don't really want the seller turning it on any more, and possibly
burning the phosphor.

This is also the symptom for a G-K short in the crt. Be careful.

I think I will not try the spray foam in a box idea- as Rob relates, it
can be a bloody mess.<< <

Certainly was for me, however; given my one off and ill prepared (and
un-documented) attempt coupled with the consequences of a successful
methodology. Well, we might want to leave the possibility more open (or at
least give it a status of "the jury is out") as there were also some
reported success. It may be something dependent on brand, method, temp, etc.
and I hate to throw it out based on my input.

Concisely if we (as a group) can find a successful method involving spray
foam it is way preferable to peanuts and could land one in as close to
original packaging as possible..

Well at least 2 cents worth that wasn't asked for. sorry.hopefully doesn't
sound argumentative, it isn't meant to..

Hopefully helpful though or at least worth the bandwidth.

Thanks everyone for your ideas!

I think I will not try the spray foam in a box idea- as Rob relates, it can
be a bloody mess.

The boxes at appliance shops (when you can get them) are often way
oversized. In the past, for padding and in order to fill space in an over
large box I have used other smaller boxes (of which I have plenty) and even
empty 1 liter plastic bottles (from soft drinks, juice, etc)- as long as you
screw the caps on they make very good filler that is stiff yet cushioning
but can't be crushed. Also, I'll put peanuts in bags, and use those bags as
filler, rather than use just the loose peanuts.

I'll look into your suggestions/ sources.

Thanks!

Keith

That guy sold me a manual for a RLC bridge once, with exactly the schematic
page missing where the fault is located.
He didn't care when I pointed it out.

I was not impressed, but I guess when you need that manual you'd buy it
from the devil and be glad.

Tek Model 130 LC Meter part needed
Sun Feb?10,?2013 10:56?pm (PST) . Posted by:
"Kenneth G. Gordon" w7ekb
Hello, Folks:

Amongst other Tek gear I own, I have the subject L-C Meter, the Model 130.

Although it is all complete, the meter "case" has been damaged (although
the meter movement is OK).

The front cover has had a big chunk broken out of the top.

Does anyone here have a spare meter they would sell for a reasonable
sum?

I would like to get this unit working as soon as I can.

Thanks,

Ken Gordon

FWIW, my LC meter arrived with a meter case that was broken in a dozen
pieces due to exceptionally dreadful packaging. Fortunately for me, I had
earlier bought on eBay a boxed new-old-stock 130LC Meter meter. So the fix
was easy. But I wouldn't hold your breath waiting for one to turn up like
that - I was just lucky.

I can't think of one off hand but would there be any other Tektronix
gear that used a similar style meter that you might be able to salvage
the bezel from. Alternatively, would Tektronix have made the meter "in
house" or is it an off the shelf meter that might be found elsewhere.

Re: Help with later 2710 power supply schematic

Hi
I see that you have worked on the 2715 Spectrum Analyzer. I have post previously a request, that you might be in place to help me solve it.
I want to find the Cable TV RF Measurement Software for the Tek 2714/2715 Spectrum analyzers. Is it still available, or is it possible to get it somehow?
Or suggestions where to look for it? I have got a 2715 and would like to have that software in my lab PC.
I think it should be similar (or even the same) as is for the RFM151 Signal Scout analyzer, but not sure also about it if it can be found. as these have been transfered to another company according to Tek site. However at the new owners there is not even a single clue about RFM150/151 equipments!! !
However for me even for that one will be helpfull as I also just got one of them. :)
Can you help on finding these, if possible please?

Best regards & thanks in advance
Sotiris Pdmtr

Subject: [TekScopes] Help with later 2710 power supply schematic



I am helping a customer locate a schematic for a later serial 2710 Analyzer power supply. His serial number is B033837. I have a later 2710 manual 070-6024-01 with change pages up through serial B021322. But the later power supply is not covered in there. The latest supply A15 in my manual is part #621-0042-00. His A15 carries a part number 671-1599-00 ... If you have any info on the later supply schematic and parts list ArtekManuals will give you a free PDF of your choice for the favor of the loan of the pages to scan. IT is possible that this supply is used in other 27xx ananlyzers as well, but I only have schematics for the 2710 and 2755 at the moment
