Operation

8 To analyze the recorded data and display it as a Bode frequency

response diagram, click on the

FFT button in the icon bar above

the graphics display.

9 Optionally, you can configure the display properties and activate

cursors using the buttons in the icon bar above the graphics

display (see the PIMikroMove™ manual for details).

This helps to identify the resonance peak on the Bode plot. For

example, you can place a cursor on the peak and read out the

cursor value which is displayed beside the graph (see figure below;

the resonant frequency is about 824 Hz).

10 When the measurement is finished, open the

Command Entry

window again and set the Digital Filter Type parameter back to its

initial value (see step 3).

NOTE

If the resonant frequency should not be damped well enough (the

measured resonance peak is higher than the highest amplitude value

for lower frequencies), then you should adjust the notch filter (center

frequency, damping) of the analog piezo control electronics as

described in the User manual of the E-802 submodule.
