Re: Tektronix 454A Oscilloscope No Trace but Beam Finder works fine?


 

Thank you for the info. I shot another video to demonstrate the issue. I have virtually tested all vertical and horizontal sensitivity combinations to no avail. I just realized that the UNCAL light was on for Channel 1 but I also adjust the var knob after I shot the video so the light is off. That said, it didn't change anything. I hope this video helps in identifying the issues.


Thanks!
