Weird 466 horizontal glitch--SOLVED

Edward Prest

Silly me. 140 volts has a glitch. measures slightly low with dmm but scope shows 120 hz 30 volt glitch.
Its the power supply cap! its amazing the scope runs as well as it does with this fault.


Power supply voltage and power quality are the foundation of everything else. This was and remains the most important lesson for me when working with these scopes.
