Wow! With sisters like that..... That was probably a type 113 delay cable. Rare as hens teeth. If it was a 113 it would've been 50 ohms Oh dear. Sniff.... Craig

Is this the same as what I've heard referred to as "hook"? Is there a good reference anywhere for these subtle second-order effects? Regards, Dave Wise

I used to have an external Tektronix delay box. It consisted of a coil of 7/8 inch or so rigid coax in a metal box with GR connectors. It was about two feet by two feet by eight inches. I don't

Hi, Miroslav, Rudi, and Stan, as another interesting (at least to me) aside ... It was interesting to note that although the acoustical delay you mention was used as described, its limited delay and

Hello Loyd, Those connectors are to power active probes (P6201, P6202, P6230) when you use them; power on connectors is: +/- 15V and +5V. There is something on rear panel of 2467 that looks like

Hello Rudi and Stan, Can not help but through in my two cents worth of comments. The quartz and glass delay lines have been used in signal processing, but not in scopes. A delay line of an

I have a 2465b that I use for simple projects. I have notice that there is 2 connectors in the back of the unit marked "probe Power". Each have 4 gold connection points inside of them. What option is

It is interesting to note that there are rather interesting compensation networks on the output (and sometimes input too) of the coax line. These are similar to the termination networks on

Hi Ernie, I may have some help in getting those instruments to a new home. There is a yahoo interest group called "Tekscopes" that has a rather large following of people who collect stuff like old

Hi Rudi, Like most electronic components, delay lines have evolved over the years. The very first ones used in Tek scopes that I am aware of were in the models 511AD, 513D, and 517 which were made in

Tantalums have a nasty tendency to short without any apparent reason and if current is not limited to a safe value, they end up as a firecracker. On the other hand, if current is limited, the cap gets

Hi Eric, The 2246 uses a Lithium battery (3 volts). It is a sort of penlite, but smaller with solder leads. It is located on the microprocessor board, which needs to be removed from the scope to

Their is a table in the 1S2 manual that expands on the data in Dave's link. It says: Silver - not used Gold - not used Black - Multiplier 1, Tolerance +/-20% or 2pF Brown - Multiplier

I have recently replaced TWO tantalum caps in TWO different 7704A mainframes. I am surprised at this and don't believe it's a coincidence. Tatalums are somewhat nasty as they tend to fail in the

Hello All; I been searching for the color codes for dogbone capacitors for awhile. I found a site that I thought mignt be useful from time to time. I thought I would share it with the

Hi, I just got a used Tektronix 2246 and I think it needs a new battery since I lose the settings after turning it off for a while. Can anyone give me suggestions/instructions on how to change the

Modern surface mount components are soldered with silver bearing solder for the same reasons. Their end connections contain silver and normal solder can leach out the silver, causing unreliable

I have been using a 545A for electronic and Radio Control hobby uses for about 20 years. I jus got the bug and bought a good 465 M and a sort of working 465M on eBay. They aren't here yet. I got

Tektronix manual for 585 says '3% silver' and that is as vague as you can get, there is no mention whether there is any lead in it. The manual also gives Tek's part number, as 251-514 and perhaps Stan
