Low cost variable freq. capacitance meter 0.1pf to 1nf

[WayneL]

Hi

Can anyone help me source a low cost <$200 capacitance meter that works over
a number of freq. A kit would be great.
Any help would be welcome.

Thanks
Wayne


PS The small Peak units are no good for my application.

Don't know what the 'Peak' unit is, but I have a AADE (Almost All Digital
Electronics) L./C meter II which spans that range. It was a kit for $100 or
so. I seem to read from your message you want to read at selected
frequencies, if so then this unit is not suited. It has a 750 kHz or so
osciilator which frequency is changed by the unknown C or L. A PIC is used to
measure the frequency and compute the unknown value. Self-calibrating,
resolution 0.01 pF and 1 nH. I like it very much.

Greetings Wayne..

Help on a board like this runs from adolescents to full Electrical
Engineers or scientist. It would therefore probably be helpful to know
what your applications actually is to warrant a worthy recommendation.

Hi

I am interested at looking at the impedance and capacitance of PCBs with the
addition of contamination over various frequcies.
