Re: Looking for Sony-Tektronix 318 Logic Analyser Operator's Guide
Hi:
It seems the Army one has a reasonable operator's section (Chapter 4?). What part isn't detailed enough?
My question is why: what can one do with a 50 MHz (1 mega-sample) logic analyzer...that you can't do with a cheap p.c. based one? (Am I missing something fun?)
Regards.

Re: Tektronix 015-0580-00 Pocket Signal Generator
This generator was designed as a sales tool, to be used to demonstrate a particular feature in the TDS600 series which had a competitive advantage at the time. I don't recall the feature, perhaps InstaView - a probability density display feature that allows differentiation of portions of the waveform that occur at significantly lower rep rate than the the portion which repeats every acquisition. Most modern DSO incorporate tools similar to this today.
As it only generates on-y this one signal solely for a pre-sales demonstration, this generator is not particularly useful for general use.

Re: Off Topic -- DC508 replacement display
Good job!!!!! -----Mensaje original----- De: [email protected] [mailto: [email protected]] En nombre de scskits Enviado el: martes, 9 de octubre de 2018 23:47 Para: [email protected]Asunto: [TekScopes] Off Topic -- DC508 replacement display Users on the TEK500 group suggested I re-post this here. For those interested, I have been working on a DC508 display replacement board starting with a design from Steve M. that was I think was derived from Paul's design from back in 2013. Basically I made changes to the board for fit and to put all of the SMT parts on the display side in the correct orientation. The diodes that isolated the decimal points were changed to dual diodes in series to slightly reduce the brightness. Also added 100 ohm series resistors in line with the display segment drive lines in case the brightness there needed adjusting. I still have to reduce the brightness of the discrete LEDs, even the low output LEDs of today are brighter than the originals TEK used. For now I will likely just change the resistors on the DC508 main board or add resistors in series in line on the LED cable harness. I think that the Mouser LED I have on the BOM now should be less bright than the ones I currently use, but have not purchased any yet to try. See pictures at: /g/TekScopes/album?id=74895I have two assembled boards and 8 extra bare boards. Note: board finish is tin/lead HASL, not RoHS compliant. All parts are in stock and available at Mouser for about $30. I can supply the remaining bare boards for $20 each plus shipping. If there is enough interest I can get another batch of boards. These are all SMT parts except for the headers... I have not decided on a price yet for the assembled boards, they take about 2 hours to build.. If interested send me your PAYPAL e-mail direct and I will invoice for the board + shipping. I think I can do first class mail on these. If they run out, I will let you know if/when more will be available ed

Re: PG506 Repair - 20v & 50v standard amplitude is low
Solved....
After tearing into the PG506 for a while and re-verifying the divider networks to no avail, I discovered a bad BNC cable between the 3456A and GenCal resistor decade I was using. The darn thing had 38K¦¸ of resistance between the center conductor and shield - just enough to load down the network I was testing. That drove me crazy for days...
I figured I would post it here to close this out and not just leave it hanging in the breeze which irritates me, and others may learn from it - verify your test gear always ;)
Thanks to the group for the help as well ;)

Looking for Sony-Tektronix 318 Logic Analyser Operator's Guide
If not too off-topic (it's not a 'scope, really, and too digital):
Does anyone have a PDF of this available? The Service Manual (military version) is available on the Internet but as indicated, I'm looking for the Operator's Guide.
A Reference Guide seems to exist as well. That too could be helpful.
Thanks in advance!

Re: 577 Curve tracer ringing CRT and noisy step generator
I will check the power supply for ripple and invest in a LCR meter to check the capacitors. It seems they make 100 kHz LCR meters you can check capacitors in circuit, maybe I will take a look at that.

I have seen these postings on e-bay from time to time and noticed that these kits use a simple circuit board whose edges are either sheared or more likely, routed with a tungsten carbide cutter. Mating the edge that plugs into the mainframe connector will likely damage it on the first insertion. The edge card connectors in the mainframe are plated with hard gold, to a thickness of 100 or 250 micro inches, depending on the vendor. This is a relatively thin plating for a connector that sees a lot of cycles. To be honest, the mainframe connectors used by Tek were not a good choice for this application. They were intended for use in semi-permanent applications, where the only cycling would be board replacement during servicing ¨C not a plug-in where they may see hundreds of cycles in normal life. The vendor¡¯s data sheet for the connectors stated that there design life is only 25 mating cycles. Note that exceeding this cycle count does not necessarily mean the connector would fail, but rather the specifications for contact resistance would not necessarily be met after 25 cycles. Tek mitigated this short life by treating the male mating fingers on the edge of the plug in. If you look closely at any TM500/5000 plug-in, 5000 series scope plug-in and the Tek made extender cables, you will note several things. First, the fingers themselves are gold plated with 100 micro inches of hard gold over a nickel plate. Copper and nickel are much harder that hard gold and will deform it when mated. More important, the mating edge is treated in two manners. First, it is chamfered to a 45 degree angle with a carbide router bit by the board fabricator. This is essential to prevent the exposed glass fibers from the board edge from scraping the gold off the connector. Again, a single mating with an epoxy glass circuit board into one of these connectors can remove considerable amount of the gold plating from the connector, rendering if venerable to corrosion in high humidity environments. While the chamfering reduces the likelihood of glass scraping the connector when mating, the step where the circuit board foil trace mates would still scrape when it mates. Tek prevented this by ¡°rolling¡± the chamfered edge of the circuit board. The finished board after plating is ran through a pair of conical rollers that actually smashes the circuit board which reduces the thickness of the plated board fingers, allowing them to partially engage into the connector before beginning to deflect the spring function of the contacts. Thus, there is no edge scraping on the connector during the mating process. The board edge engages before it begins to force the contacts open. Users who buy these extender kits can do some of these steps to improve them to prevent connector damage. Using a file, it is possible to put a chamfer on the mating edge. A short length of steel rod can be used as a roller to manually squeeze the connector edge. The only thing the user cannot do easily is add the gold plating, but the contribution of plating is minor compared to the problems of mating a rough exposed epoxy glass board into the mainframe connector.
