Thanks Bill, your reply clarify things for me, as I said, it probably is an elementary question but I could not find any reference in my library. 73's Joe Orgnero VE7LBI

Hello stan, If you still have a copy of the Tek anniversary book available, I would like to order one. Let me know the cost of surface mailing to Canada. Thanks

Joe, It is more or less backwards from the way you ask the question. The scope input C was determined by the available technology and design skill at the time. Reducing the C at the scope input has a

Hello all, The recent messages on the subject of RC Normalizers got me curious about the values of capacitance in the input RC of scopes. Looking through an older (1971) Tek catalog I noticed that the

Hi Peter, The first item, VP-1, is a "voltage pick-off". You insert it in series with a 50 ohm cable and plug a P6056 or P6057 voltage probe tip into the little hole in the plastic part. This allows

Hi Michael, I am the guy who wrote, "OSCILLOSCOPES--Selecting and Restoring a Classic". I still have a few copies left for $24.95 and I also have a 1989 Tek catalog that covers your 2235 that you can

This is well put, Bill. My thoughts as I read it for the first time were that it seemed to dwell on "politically correct" issues a lot, like answers to why Tek located a manufacturing plant on the

Hi Miroslav, The Tek 40 Year History book is called, "Winning With People: The First 40 Years of Tektronix" by Marshall M. Lee. I don't know of any other official Tek History books. The current bunch

Hello Miroslav, I suspect this "Pomona Box Inductance Standardizer" is not a Tek item. I have never seen one and the Dymo labels tell me a lot . . . The S-30 is a box with standard capacitors and a

Thanks very much Joe. I'll go hunt it down. Phil

Hi Dave, :) Thanks for this information. I'll give it a try. Kind regards, :) Michael

Miroslav, it's interesting to find stuff that WAS made by Tek but not for sale to the public. There are some 067- calibration standards in that category and bunches of tools. For instance, the

Fred, Tek quit calling the procedure "standardizing" and began using the word "normalizing". They realized that it was pointless to "standardize" the scopes to 20pF or whatever ... in fact, if a

there'sone one ebay now with a buy it now! good luck!

Hello Micheal, One place where you can at least view testgear catalogues online is http://www.testmart.com/advice/advicetmp.cfm They have copies of Tektronix catalogues going back over a number of

It's the 24 pf version of the device we posted about a few days ago. Read all the posts about the 15 pf 2input normalizer (067-0537-00) - same deal. Phil

I don't even know what these are or how I got them but they are some sort of inline RF devices with GenRad 874 connectors on them. One is marked VP-1 017-0073-01 Zo = 50ohms (it has some sort of

Fair Radio Sales is selling an Input TC Normalizer (Tek No 067-0539-00). Does anybody knows if this a discrete item or if it was part of any other equipment (scope, probe, test device , etc). It seems
