An equally vague answer to your vague question is us a network
analyzer with an impedance function if you need to measure impedance
over a frequency range. Hewlett Packard (Agilent) makes these. HP4195
and Agilent 4395 come to mind. This will allow you to measure complex
impedance from 10 Hz to 500 MHz with the proper fixturing. Although
the spec *** says it will measure impedance above 100 kHz, the
analyzer will do impedance measurements below 100 kHz if you use DC
coupled fixtures - at least in the HP4195.
