I reciently purchased an old 20MHz analog scope, and I have no probes.
I will mainly use it in 5V circuits, to measure signals in the range of 0V-5V, sometime up to 12V, and very few, up to 15 or 20V.
I have the chance of getting at good prize, but not for free, 10X probes, but no 1X probes.
10X probes may atenuate the signal too much, so If I need to measure a 5V signal, 5V will be 0.5V, and so, these probes may be not suitable for me.
I looked up the sensibility of my scope, and it says 0.5 div internal, and 0.5V external... I'm not sure about what it means. what is minimun voltage change that can be measured? By the way vertical divisions ranges from 5mV to 5V.
Can you please give me some advice??
thank you!
