So do I. I sold mine, for the following reasons:
I do like the 7CT1N
- I have both a 576 and 577 dedicated curve tracer
- A while ago I bought a "home-made" 5CT1N-like module (yes, for the 5000-series), designed and built by an ex-Tek employee. The 5CT1N module, having no readout (hence -N), exists for the non-readout, slow 5000 mainframes but this one is equipped with read-out functionality, built with 7000-readout components. This allows digital, on-screen readout for step, horizontal /div. and vertical /div. All hand-wired, no copper traces! Multi-position switches instead of pots for selection.
THAT is a definite piece of art. I've got a design that makes a
digital curve tracer. Something like the Tek 472 if I have the
numbers right. +/- 20 volts, digital, and current readings down to
about 200 NA full scale....
One of those.. working on it.... designs, with three
microprocessors.... (two for current/voltage supplies).
