Where do these plugins fit ?
I can get for nearly free ( 5 Euro = USD 6.50 per pc ) some scopes and plug ins : 3S76 3T77A 3T4 3S2 as well as the scopes RM564 ( incl. 3S2 and 3T2 ) and a RM561A ( incl. 3S1 and 3T2 ). Do all

Advice wanted first time servicing a scope Techronics 549
Dear Friends I have a small collection of test equipment and recently been donated a Techtronics 549 storage oscilloscope. The unit has had little use but many years of storage makes me think a

Re: Oscilloscopes 101 - eBay
My favourite is the Tek 111 pretrigger pulse generator. This is an avalanche pulser, and gives a really clean 400ps rise time. Since it has an adjustable delay between a pretrigger pulse and the

4xx Portable Feet Repros Available
OK folks, I think I have the process in pretty good control. I am willing to cast some replacement feet for 453, 454, -A, 464, and I think they also fit the 465, 475, 485 series of scopes. (These

Re: Oscilloscopes 101 - eBay
Have seen some unbuilt Heathkits (scopes and other pretty trivial gadgets) go for astronomical prices, though I'm not not looking often now. Ego-bid war between two will do it: $900 IIRC, and several

Re: lethality of HV
Ironically it was at Siemens where I was working for when one fellow got electrocuted. It seems he grabbed on to a 480VAC 3 phase buss while pulling himself up from underneath a linear accelerator.

Re: lethality of HV
Twenty years ago, when I worked for Siemens in Munich, after hours, if there was no one in the lab we were not allowed to work with anything electrical, that included 5 V lab supply, soldering iron

Re: lethality of HV
One of the better (and readily available) devices to painlessly dissipate static charge is a quarter coin. I hold on the most of the surface of the coin and touch grounded surface with exposed part of

Re: lethality of HV
In the Tektronix book "Biophysical Measurements" book, it states that it only takes 10mA of current to stop the human heart if a circuit path through it is created (like hand to hand or hand to foot).

Re: lethality of HV
More about static electricity - it takes 5kV to even have a sensation from it, due to skin resistance, etc. That is why static damage is so easy. Some components like JFETS can be damaged at
