Hello all, first time posting here. I'm glad I found this site...the sheer amount of info available is incredible.
I'd like some clarification on max input voltage for scopes. I own a Tek 475 and just purchased a 465b, which should arrive within the week. Both tout max inputs of 500v...is this max assuming a 1X probe? I can't seem to find any clarification in the manuals, or maybe I'm overlooking it. I have tried searching this site (and others), but can't seem to find anything...I'm sure the info is here somewhere, but I don't seem to be doing a good job in my searches.
Also, again just to clarify, if I'm using a 10X probe, it attenuates the voltage by a factor of 10...so if I probe 500v, the scope will only see 50v, yes? Or does it actually see the full voltage, but displays an attenuated signal? I realize the probe will see the full voltage, and naturally, safety/caution measures are in order...I'm not going to be poking around extremely high voltages just willy-nilly. I'm using these scopes, currently, to build/repair tube guitar amps, so the max voltages will be, generally 500-600v, and only that high in certain parts of the circuit(s).
Another general scope question. I've noticed that a lot of the new DSOs and probes have lower max voltages...around 300v. Why is this? Maybe because the modern SS circuitry doesn't typically require such high specs? Is it to save money and keep costs down? A little of both? Just curious...
Anyway, I've rambled enough for my first post. I appreciate any and all input.
