Re: Tektronix 2465
Gerry, yesterday I adjusted the 10V voltage and runned through the crt adjustment procedures. The screen is now absolutely normal. It could, indeed, have been a previous attempt to calibrate the oscilloscope. Now I'm studing how to finish all the steps required to finish the calibration.toggle quoted messageShow quoted text
One thing I noticed is that the vertical readings are wrong. when I input a 2 Vpp saquare wave (or any other wave form), it shows something near 2.5 Vpp. I think the self call procedures will repair this. What do you think about that?

One of the calibration procedures produces those series of dots when setting the vertical limits, if I remember correctly. It would appear that whatever initiates that procedure is somehow "stuck on." I'll try to find which procedure it is and report back.
