Amplitude Unit of Real Part of Frf

[bnz]

Hello,

I can see real part amplitude of FRF results of impact testing on signale xpress.But,it only says amplitude.Please check attaached picture.

What is the unit of amplitude?I need it in mm/N or m/N.

I made the test in a way what force is Newton and accelerometer is g unit.

Thank you for your help.

Hello,

The software only handles voltage, there is no way for it to learn what the unit of your measurement is.

You should be able to obtain this information since you are the person configuring the software to do measurements. 

This depends on the instrument you are using, you should look for a way to scale this measured voltage to the actual units of measurement. You may find this on the datasheet of your impact sensor.

Success!
