CF-5200 Frequently Asked Questions
Question number FAQ-0382
When you double integrate the power spectrum of acceleration, the components disappear.
The formula for calculating frequency integral is as follows: If a is the value of the LIN spectrum at a certain frequency F (not expressed in dB), then
Single integral = a÷(2πF)
Double integral = a÷(2πF)2
Integrating results in a small value, causing it to be displayed as a small image at the bottom of the screen. Using Y-axis auto-scaling is helpful.
