Stan, Did you get my messages on the tunnel diodes ? Phil

Let us not forget that not all terminations are equal. I will take example of few terminations that Tek supplies: 011-0049-01 is good up to 500 MHz, then 011-0099-00 good probably to 250 MHz and then

You can also try this address: http://www.sphere.bc.ca/test/tek-parts/tekparts3.html <http://www.sphere.bc.ca/test/tek-parts/tekparts3.html> . I came across it on e-bay; they seem to specialize in

Deane Kidd sells Tek 011-0049-01 feedthrough terminators for about $10 when he has them. Probemaster has one, model 1055, that sells for about $33. They tend to turn up in scope cart drawers and

Anyone out there interested in adding some vintage Tek scopes (50x, 53x, 54x, 56x series) to their collections ? I've been offered a bunch, essentially for free. There are too many for my already

I'm not sure who you were directing this message to Chuck, but I do have a type 82 plug-in that may be surplus to my needs. Possibly a manual for the 585 and the 82 too, but I'd have to look. Phil

I believe that a question did come up somewhere concerning where one could buy an in-line termination. Besides the obvious expensive source (http://www.tek.com), I believe you can get them from

Hi, I have a 585A too, bought it more for the nice (exotic!) inside than for the nice outside... And I asked myself exactly the same question you are asking yourself. In this way, it is not a fun

Hi, What plug ins for the 585A do you have? Prices? Shipped from where? Thanks. Chuck

Hello, I am new in this group. I have bought an Tektronix 585A oscilloscope from the Swiss army. The condition is after 35 years storage in a air-conditioned fortress like ex works. It is a very good

That's what happened Doug. Tek bought Telequipment in late 1966 in order to capture some market share in the "low end" scope market - a market where Tek had no presence at that time. Telequipment

I thank everyone who responded. Here's my next thought: What about loading the test circuit? Suppose I connect a 50 ohm terminated cable from my 547's calibrate-out jack to the 1A1's input. With

The intensity control makes no change. Traced the 3 wires and found 1 that has no connection. The other 2 are hooked to the beam finder and the hort. plug-in. Also the p/s volts are off and

(snip) 1MHz signals My humble twopence: Crappy rule of thumb! Few years ago while integrating an ATE we had a 1MHz square signal we thought it wouldn't need matching pretty much for the same

Be careful using "network-grade" coax terminators for high-frequency RF. The ones I've seen become reactive as heck above 50 - 100 MHz or so. Unless you have a way to check their return loss at the

Jim asks: Basically, the phenomenon you're trying to avoid here is signal reflection. What coax does is provide a path with a known impedance to carry the signal from point to point without changing

A few months ago, Dean Huster had included the following in a post: "You don?t HAVE to use a termination on coax if it?s a low-frequency signal. For high-frequency or fast-pulses, yes, you must

Hi Stephan, Try asking to "Deane Kidd" <dektyr@...> He has lots of Tek spares. I have bought from him several times. Good
