some of the chinese fakes do actually work and identical to the original but since their date code is also old they ma not last that long I also got several fakes that didnt work until I got this one

Hello all, thank you very much for your replies. Here is my list of actions (so far): 1. The 'chinese part' worked ok in a programmer (readable, writeable, reasonable content in the registers

I'm giving this another try in this thread. This message is directed at Dave Brown (Tek Museum): 1. Do you consider these files free to unlock for the purpose of OCR'ing, possibly reducing in size,

Raymond: Thank you for all the trouble you are going thru. If the connector is the correct one (it is only about 5/16" diameter with a "D"-shaped 4-pin insulator inside), name your price and I will

From Tim P (UK) Many thanks for that - as I suspected, it is necessary to unsolder the delay line and re-attach to the interface board. :-( Otherwise a topological conundrum involving a fourth

Since a previous message to this group I have been seeking an explanation for the scarcity of of available information on tthe TDS3PRT printer and the reason for its discontinuance. I have been hoping

Please post. larry

A DS1742W from China? Chances are really high it's a counterfeit. Here's an eevblog thread that has some pictures of a China fake vs real:

Hi Nick, the dot pattern is not what I expected. It seems that still linear interpolation is done to fill missing horizontal positions. I expected to see no dots at all during some wide horizontal

100nsec per div and faster sounds like the switch from real time sampling to equivalent time interpolation (300Msample/sec real time). You can turn off the equivalent time mode by going to the Acquire

Hi, I own the HC100 plotter with the RS232 option. I'd be happy to swap this for the GPIB option if anyone out there has one they don't want. Sorry I don't know the part # -- it doesn't seem to be in

Q141, sheet <11> coordinates E2. The other transistor in the clamp is Q41, coordinates E5. Dave Casey

Thank you for the suggestion Dave, I'll have a look at where the power supply points are located in the manual and see if anything seems out of spec when I'm next able. And in response to Albert, you

Szabolcs, from here (TekScopes) posted a method of accessing the internal battery of the Dallas NVRAM modules using a heat gun and a scraper. The difference in these modules was that there were two

Not your current problem but I replaced the NVRAM chips in my 2440 and the scope doesn't work.? I switched one of them back and still no joy.? I will try the other one. I probably got some

I picked up a 2440 on ebay that had the dead nvram battery problem. Got that fixed up with an external battery. Ran thru the self cal and ext cal and all seems fine, except when the sweep rate is

from Tim P (UK) Does anyone (Hakan?) have the documents detailing the conversion between rack / bench formats ? they are 040-0583-02 and 040-0584-03 I don't see how to do it without unsoldering the

Slight correction. From the manual, it appears TP60 (et. al.) has a 28uS period making that about 38kHz instead of 30kHz. Thanks, Barry - N4BUQ
