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 ;-) Fred PA4TIM Op 11 feb. 2013 om 21:54 heeft Dave Daniel <kc0wjn@...> het volgende geschreven:

Re: PYRAMID CALIBRATOR AND TESTER FOR TEKTRONIX OSCILLOSCOPES
¿ªÔÆÌåÓýThis instrument was specifically discussed a while back. I'm trying to locate the emails I have; I can't recall whether it was in open forum or a series of private exchanges. The person who is selling these wanted something that he could carry around to Hamfests and other places and use to quickly evaluate 'scopes before he bought them. It looks like a very nice instrument to have, IMO.Dave On 2/11/2013 1:47 PM, ukchastuck wrote:

PYRAMID CALIBRATOR AND TESTER FOR TEKTRONIX OSCILLOSCOPES
Anyone ever tried one of these: to test and calibrate Tek oscilloscopes? The ebay description of the Pyramid Generator implies it can be used to reliabily set vertical amplitude calibration, horizontal time calibration and triggering capabilities. Seems you get a lot for your money if it works.

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

The good news is that replacing the Motorola part with the Tek
specified item produces a cure & all is good again.
?Probably not relevant but the Motorola part was
aluminium, and featherweight, the original part is steel and of
substance.?I think the problem was junction heat related, in that there was a
direct relationship between length of 'off' time, in days, and 'on' time in
minutes, with a minimum of 1 day 'off' to get any 'on' time at
all.

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. --- In TekScopes@..., "Christopher Hilton-Johnson" wrote:

> >Could this be correct? >Raymond Raymond 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!

Information please.
I have a 7L14, where the 1st LO has just died.
It seems the main
YIG driver transistor, an NPN Darlington, has already been replaced
The Tek part number
is 151-0454-00, but this bears a Motorola number SJ6796 and a date code of

Anyone got any

best packaging is bubble wrap. Its expensive but does the job really well. In my career in computer peripheral sales I watched many a customer do what their packaging engineers called the ¡°shake and bake¡± ( temperature and shock and vibration testing) on products that they were about to purchase ( thousands of them) and ship globally. As to packaging, they said the best was ¡°foam in place¡± where the unit sealed in plastic is immersed in a liquid that turns into form fitting hardened foam. The worst protection the packaging engineers said was ¡°peanuts¡± because they tended to shift in the box resulting in too much peanuts in one place and none in another. As to bubble wrap, they said it was great stuff but far too expensive to use in high volume shipments. For my purposes, a good sturdy box and a scope wrapped with several layers of bubble wrap always did the job spot on -----Original Message-----

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!

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?

People who rent moving trucks need to pack their stuff. They also have corner protectors: ? Also:?? I think the best way to pack a scope is a box-in-a-box approach, with peanuts or foam between the boxes.

If that doesn't pan out, I may take you up on your offer, if it's not too late! Thanks, Chris --- In TekScopes@yahoogrou ps.com, Bob Albert wrote:

Posted by: "Peter Bunge" rovmkr 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.

You could bypass the original flash circuitry and devise a one-shot multivibrator (e.g., a 555 timer) to pulse the LEDs. 73-- Brad AA1IP Reply to sender . Reply to group . Reply via Web Post .

Posted by: "Dennis Tillman" putz_with_ear_lappers 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?

Posted by: "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 -- Paul Amaranth, GCIH | Rochester MI, USA Aurora Group, Inc. | Security, Systems & Software paul@AuroraGrp. Com | Unix & Windows Reply to sender .

Posted by: "Rob" doswoodman@... can be a bloody mess.<< <I think I will not try the spray foam in a box idea- as Rob relates, it 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 Reply to sender . Reply to group .

Posted by: "Stefan Trethan" stefan_trethan 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.

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 Reply to sender . Reply to group .

Alternatively, would Tektronix have made the meter "in house" or is it an off the shelf meter that might be found elsewhere. Don Black.

Posted by: "pdmtr" pdmtr 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?
