Below is an example of the FFT live display with linear
units:
The following explains each of the display’s components:
In this case it shows 20.12 milli-g
acceleration.
Standard dB level at cursor - This is the dB display which
appears whether or not the linear amplitude is displayed.
Read out at cursor - This is the linear units level at the
cursor.
NOTE: The units level is displayed in engineering
exponential notation.
