Advanced tests of acceleration measurement
Use the shaker and sensor if you are able to shake high frequencies. If your shaker system does not
allow it, use the signal generator and switch the ICP off. Contact your re-seller for information, how to
switch the ICP off. That information is not written in this manual.
You can make the frequency response and the amplitude response.
Use the amplitude 1g for frequency response test. Change the frequency from 500 to 12000 Hz and
draw the curve.
Set the 1.2kHz or higher for amplitude response. Change the amplitude from 0.1 to 10g and read
values.
Envelope demodulation test
The envelope value is RMS value. Do not use comparing with peak values. Switch the ICP off and use
the 8kHz pure sine signal with 1g (100mV) amplitude. The ENV should display approx. 1.33g.
When you use the A4801 Sensor Simulator do not switch off the ICP. Remember, that A4801
generates 0.5g only. That is why the ENV will display one half of 1.33g (0.66g).
