Hi Jon,
? ?I have a copy of Dean Venables book: "Stability Analysis Made Simple".? I bought that for $30 back in the Mid 1980's.? Retired for several years now, this work is just as a hobbyist.? I do still teach on online class in first year physics for New York Empire State University.? If I win the lottery I will look at a Solatron 1250 or similar.? Otherwise, I am on an Ebay budget.? I see Venable equipment for sale but usually as "parts only".??
Having been burned before on Ebay I avoid that class of equipment.? My 7623A will work as long as I keep both channels on the same scale.? Using different scales is going to require a lot of thought (I was hoping to avoid that - lol).? Have a great day.
