Re: Introduction of myself!


 

Hi David and Brian,
Yes, the 7S14 is much easier to use, and it is dual channel with a dual
timebase which makes it an excellent sampling combination. Plus you can
usually find them for next to nothing. Bandwidth is limited to 1GHz which is
probably going to be fine.

This is the bad news... Mercury is banned in most countries.
Unfortunately the mercury cell in the sampling front end of each channel is
certainly dead by now. These plugins are all 40+ years old by now. The
mercury cells lasted 10 times longer than anything made today but 40 years
is impossible for any battery. There are no direct replacements for these
cells. Space inside the front ends is very tight which limits the possible
alternatives.

Alternative ways of powering the sampling front end have been discussed
(look in the archives) and if you can live with one of those solutions a
7S14 would be a excellent solution.

I was going to suggest the 7S14 instead of the 7S11/7T11/S1/S2 because it is
easier to use and I believe easier to maintain.

Hi,

Welcome to the group!

Buy the 7S11 and a 7T11 sampling plugins for your 7613. Then get an S1 or
S2 head for the 7S11. That will allow you to calibrate the 106. It will also
teach you about sampling measurements which are a fascinating aspect of
oscilloscope measurements.
