Re: Scope probe recommendations


 

Normalizers allow adjusting separate inputs to the *same* capacitance but not
necessarily to a specific absolute capacitance. This allows compensated probes
to be moved between channels without readjusting probe compensation.

A x10 probe may be used as a normalizer which is just a 1 megohm resistor in
parallel with an adjustable capacitance placed in series with the input. A
normalizer operates like a x2 probe.

Hi,

There are normalizers available that allow you to adjust your input amplifier to the specified input capacitance. Once that is done, you can adjust your probe for those inputs. If you have an input that has not been set with a normalizer. you may have problems with interchangeability. Once you adjust a probe to an unknown input, you are flapping in the breeze.
