Measurements at the above date show:


BE, with and without the amplifier:

Frequency=19 kHz
Beside the shift, amplitude is changed.

Free vibration, with and without BE.:

Frequency=21 kHz

Influence of input voltage:

Frequency=19 kHz

Influence of the input frequency:

Voltage=2v*10

Notes:
  • Using the amplifier has considerable influence over the measurements at this scale.
