How to measure inductance indirectly?

hey all,

I only have a pulse generator and a O-scope to measure the inductance, and the pulse generator produce around 10Mhz to 30 Mhz, i think, would that drive the inductor to saturation? (I have few inductors with range from 150uH to 330uH, but keep giving me false result, so i suspect they have miss labelled.)

also, could someone please clarify on which voltage to measure on the o-scope for the inductor? (just the highest peak value ?) then how to get the current drop for the inductor ? thanks a bunch ..

Saturation is more a factor of the imposed voltage. However, for ferrite or iron core inductors, the permeability of the core is a factor of frequency. Measure at or near the design frequency of the device. If you are testing inductors designed for use at power line or audio frequencies, a measurement at 30 MHz may be practically useless.

As low as possible. However, by increasing the voltage, you can find the inductor's saturation point as well.
