Craig, The option is 122C and Tek calls it 'High Voltage Diode Check'. I do not have that option on my 575 but I infer from manual that current capability is less than 1 mA: manual recommends to set

I have never heard of 571. But, Dave, I take exception to your leap to 576. As a proud owner of a 575 I can not let it go by that you skip mentioning the old transistor tracer stalwart. Regards

Hello Craig, You might want to consider using a wire-OR of 2-input open collector NANDs, e.g. 74LS38. It is still a kludge but it is only one IC with few wires and a flying resistor. If you place a

Not that nuts - they are quite rare and very useful if you do a lot of repair work. Even the 500 series extenders go for $20-50. Regards, Dick S.

Tektronix 067-0616-00 Calibration Fixture Item # 1689683477 The flexible version sold for $270.96 I'd like to have either one but that's more than I want to pay.

Those are worth their weight in gold if you need one, though. I paid more than that for a set of 492 extender boards and haven't regretted it yet. -- jm

Hello Jim, I would be very interested in some of the manuals I haven't been able to aquire, I will look forward to seeing what you have, perhaps we can exchange some information also. William de Bruyn

Thanks! Now to find enough time to wade through all that. It's a dirty job, but somebody gets to do it :-) Regards, Dave Wise

Hi All, I have a 2246 with a bad input buffer amp module on CH.1 The service manual says the Tek part number is 165-2154-00. But the modules themselves have 165-2232-00 printed on them. The modules

This one really is nuts - 1692324316 - a Tek 7000 series card extender closed at $162.50 after 9 bids. Craig

Hi Stan I *thought* it had a 2 and a 1 in it somewhere! That comes as no surprise whatever ;-) On another topic, I was picking up a piece of AVO test gear this morning for a guy I know quite well, and

Hi Craig, The 575 option you are thinking of is called "Mod 122C". I have one. Stan w7ni@... Craig Sawyers wrote:

Hi David, I think you are thinking of the 575, not 571. I don't think Tek ever assigned 571 to any instrument. Stan w7ni@... David Wise wrote:

Hi Jose. Well, the only overseas shipping experience I had is the reason I started doing my own packing. The only reason the package survived was because it was an R-390A and CV-591 (going to

I'm still hoping someone can send me a scan of the 7A12 plugin schematic. I think an online manual library is a terrific idea, I have some manuals I can scan if needed. Don Black. William de Bruyn

No - this was a Lorenz machine, type SZ42. SZ is Schlussel-Zusatz, or cipher attachment and 42 is the model year. Works by taking serial 5-bit Baudot plain text and then encoding it in parallel by

Someone with more money than sense, Phil. Craig

Jim, We had a long discussion about copyright last year. If we were to have a private library for anything not specifically in the public domain we should have no copyright problems. If you own the
