Low Frequency 100kHz measurement fluctuate

Hi,

First post here. I use Agilent 4396B impedance analyzer with 100kHz to 1.8GHz range.

Today, I attempted to measure low frequency sonar transducer with the equipment and run into a bit of trouble:

- The transducer should have resonant frequency at 200kHz range, but the resonance peak is fluctuating severely and I could not resolve its impedance. (which seems to be more than 1k ohm...)



Please let me know why this is happening (too much reflection??) and if there is any trick for getting around this issue. (power / IF BW / List Freq settings etc...)

Thanks in advance,

Michael.
