I am repairing and upgrading guitar and hifi amplifiers, and i want to take it to the next level, and get myself a scope for that. I only know, that i wont need a scope with digital storage, cause im only going to be reading sine waves (potentially clipping or turning into square waves), in real time. I really dont want to overbuy this, and get features i wont need for this purpose. If getting a cheap used analog scope is sufficient, i'll stick with that.
What analog bandwidth is recommended/needed for repairing audio equipment?
When measuring a continuous sine wave loop, is equivalent time sampling enough (im thinking cheaper scope)?
What else to look for in a scope, wich sole purpose is displaying sine waves; ex. setting bias to controle clipping/checking for distortion ect. finding clipping in circuit, to replace bad part, or adjust bias.
