Just to be clear I'm pro 'scope....goes without saying for anyone who's read stuff by me on this and the UKVRR forum over the years.
But not to forget that only a short time ago the OP seemed to be surprised why he could not get a voltage measurement on some of the transistor collectors in a simple radio.
Lot to learn, if he's learnt it in the meantime then that's ok but if not then it's possible he might struggle with a scope early on (he seemed to be struggling with the concepts of his function generator in relation to the workings of his radio in another thread)
We had scopes at tech back in the day when I was doing my City Guilds (1964) Weren't let near them 'till after year one, didn't need a scope to see a sinewave, just drew one on some paper derived from a circle then drew some out of phase ones to understand AC theory stuff, those and other concepts should be learned and there's no better way for self reliance than to learn them from text and draw the waveforms etc and do the calcs etc, then later on a scope can then prove in real time what you have learned.
Just concerned that the OP might not be able to grasp the concepts and workery of a scope whilst also trying to grasp some basic electricity/radio concepts then find it all too much and say it's not for him and give up.....
Learning a lot of this stuff is like falling of a log, a lot of it is easy, yes there may be some tough bits but if you follow without staring or thinking too hard then all will come good.
