--------------------------- The measurement is made at H.F. I'm sorry, I apparently confused the issue by saying the applied square wave was at 60 kHz. That's NOT the measurement frequency. The edges of the square wave include components extending through the H.F. range, at least. The inductance is measured directly by noting the effect it has on the edges of the square wave. The advantage of that system is that it measures the inductance directly. And a shift in the inductance of about 9% was observed by scrunching the turns together.
