text: electronics - can an oscilloscope be used for low frequency evaluation (1-10hz) ? real novice here: i'm looking for an o-scope on ebay and i notice they're rated 20mhz or 100mhz etc. in general, can these be used for low frequency such as 1-10hz which spec should i look at in the spec sheet to determine this? i know for sure that the o-scope can regester the vlf waves. that is the wave patern that is natural. (the world talks in vlf) i would not know where the info is located on the net. try googeling o-scopes.
