69883Re: [softrock40] Measuring toroids inductance
- Nov 10, 2012Paul,Not sure what the basis for that claim is. The PIC and similar have worked for all the RF stuff I’ve done but you may have a special application.In any event, if you need something better, take a look at a VNA. That will let you do anything your heart desires.73/jeff/ac0c
With all due respect, there are scores of similar pic based circuits around.
What I need is a pic based, but the coil measured under a high RF frequency.
That is the only way to obtain very accurate readings, especially for us, at RF !
Most use audio or slightly higher frequency, which is not enough !

Or try this:"the kit from G4HUP available from http://g4hup.com/LCM/LCMeter.htm which is only LC but excellent for measuring and matching caps including SM parts and winding coils for HF/VHF

A few years ago, I came across a Russian inductance meter kit.
Mnay designers claim to be the best one around for accurancy.
Anyone has the details please ?
Many of the popular meters around are dubious about accuracy, because inductance is not measured at RF, but anything but RF !
