Oscilloscope Calibration or Repair?
« on: February 05, 2020, 01:48:00 AM »
I have a Tek TAS 465.  It was an evil bay special. The display has always had a blinking quality to it. In the photo you can see it’s not a crisp trace.  There are light and dark parts.

Then today I got that superimposed low frequency wave. The tone is 10K. I was driving myself nuts trying to figure out what i was seeing. I then removed the DUT and it was still there. I power cycled the scope and it went away.

The text on the display also looks wobbly.

Do you think if I get the scope calibrated it will take care of these display issues or does it need to be looked at in more detail. The calibration houses don’t do “restoration “.

This guy has a quick video on this unit. Maybe you could reach out to him for any direction on what to look at .

Thanks! It looks like he is dealing with the same sort of display problems I'm having.
