Inductance Measurements

You can use the current probe to measure the inductance of coils that have either a low-impedance or high-impe dance pulse

source of a known value.

Low-Impedance Pulse Sources

This ﬁgure shows a constant-voltage pulse

generator of extremely low output im pedance

connected to an inductor that has low

resistance.

1. Connect the inductor across the output

terminals of the pulse g enerator.

2. Maintain a constant voltage across the

inductor.

3. Clamp the current p robe over on e of the

source leads.

NOTE. If the probe impedance is a signiﬁcant

part of the total circuit indu ctance, measuremen t

accuracy will be affected. Refer to the probe

speciﬁcations for probe insertion impedance.
