Hello,

did you already read chapter 5.12. Impedance of the SysTune Manual?

Charlie's text is for EASERA, but it is correct for SysTune as well.

Hi...i am a new user here.I need to measure my speakers impedance. Is there a simple method?
I am thinking about sending a tone with 1 volt amplitude and mesure current. I could then calculate impedance for that frequency with Ohm Law. V=Z*I Then, i would repeat for many different frequencies.
Will that work? I have read method about constant voltage or constant current. But the method above is so simple, why do it differently.

Hi,

You can try and check if it is worthwhile the time you spend.

The updated article from Charlie Hughes can be found here:
