Re: Coax BNC Cable Termination
Your thesis is entirely based on a 30-metre stretch of cable. However if you had carefully read my email, the lenght in question was quite inferior. A mere 5-metre chunk of cable if that

Re: Tek 585
There aren't a whole lot of plugins ever specifically built for the 585A. Really, just the 82 and the 86. The 84 is a test plugin for the 580 series, also known as the 067-0523-00. The type 81A

Re: Coax BNC Cable Termination
That rule of thumb is not crappy, but there is a caveat: an unterminated cable appears as a nasty, predominantly capacitive impedance; for your run-of-the-mill, polyethylene cable, capacitance is 30

Re: Tek 585
I am not a former Tek employee, just an old user of Tek scopes, but I will take a stub at your question. Tektronix entered (not created) oscilloscope market; in that market synchronized (as opposed

Re: Sources for Terminations
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

Re: Sources for Terminations
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

Vintage Tek scopes anyone
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

Re: Tek 585
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

Sources for Terminations
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

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

Re: 465M Flaky vertical height.
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

Coax Termination - Circuit Loading?
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
