Lots of passive scope probes have a x1/x10 switch. In all my years of engineering work, I have never switched one of these probes to x1. The only reason I can think of for having this switch is in case your scope doesn't have a x10 probe setting, but then I've never seen such a scope. Is there any technical reason why you would ever want to use a probe in x1 mode? -- Heron 16:14, 26 July 2006 (UTC)
Heron just switched the Z0 discussion into the present tense and, while I'm sure these probes are still used and I agree with those edits, they lead me to wonder: Are new Z0 probes still being sold by anyone? They're certainly obsolete; I was looking at the specs on one of our FET probes and in every area except dynamic range, it blows the Z0 probes away:
Again, except for the price (probably) and the fact that the Z0 could withstand ac signals of about 15 volts RMS or so, the FET probe wins hands down. And the particular one I cited is wonderfully miniaturized with an integrated ground foot.

In this extract:
"At low frequencies (where the resistance of R is much less than the reactance of C), the circuit looks like a resistive divider; at high frequencies (resistance much greater than reactance), the circuit looks like a capacitive divider.[1]"
I think at low frequencies the resistance is dominant, thus it looks like a resistive divider, and at high frequencies the reactance is dominant, thus it looks like a capacitive divider.
I have not made the edit because I may be wrong and would like others to confirm. — Preceding unsigned comment added by 118.209.58.71 ( talk) 10:02, 13 July 2014 (UTC)
