Default Re: Tektronix 545 Oscilloscope fault

A very nice scope, a piece of history and still very usable.

You have the differential vertical amplifier in this example. This has 2 inputs, but its displayed as a single trace showing the difference (A-B). This will work as a normal amplifier as well, but it is only single trace and will be somewhat slower that the non-differential amplifiers. It would be nice to find a multi-trace plugin amplifier to go with the scope, these can occasionally be found on the well known auction sites ...

There is a calibration signal generator on the lower right. It will be a good test to connect that to the 'A' input with dc coupling and the timebase set to 1mS / div. Make sure all the RED knobs are turned to their 'cal' position (detent).
