oscilloscope probe circuit model
Dear rkodaira
thanks alot man for that simple effective explaination u did, i was thinking it's simple but now i'm sure and wondering : why this high price for the ready made probes?
well, i have just a little questions if u don't mind , even some of them didn't relate to the construction method, but get themselves popup in mind
ok , let's ask the important things that related to the construction methode
shold the resistors be in array?
i mean should i use the values u mentioned in series or i can use a 9 mega ohm resistor if available ?
i think it's better to have a little number of resistors , so if i could manage a one or two equivalents 9 Mega Ohm, it's better .. am i right?
i think if i got only one resistor and used one trimmer in parallel to it , the size would be greatly small to fit into the probe head
for the trimmer i think it's easy to get but 5pf is so small value , i'll try to and when i manage all the required things i'll let u know
finally i'd like to thank u very much again for ur help and support
best regards
