As I gather up all the stuff I need to test and maintain my newly purchased 2235 I am wondering how necessary it is to use a 50 ohm feedthru termination when sending test and calibration signals into the scope. Can one not construct their own device that perform the same purpose as a factory-built feedthru?
A T-connector with a termination on one end will work for
oscilloscopes that lack internal switchable terminations which
generally only have a bandwidth that extends to 100 MHz anyway.
And, can anyone recommend a good book that goes into detail on the theory of construction and operation of oscilloscopes? The ones I have gotten at the library are pretty superficial.
Jim Williams' book has a great section on oscilloscope vertical
amplifiers among other things:
