Dynamic Vibration Random Testing

Have you ever performed a, "dynamic vibration random test" before?

I meant can it be measured directly during random testing.

Most hand held vibration measuring instruments will measure velocity, acceleration and g. What kind of checks are you planning and with what type of instrument?

I am using m+P vibration control system which reads freq. vs G*G/Hz(PSD) value.

i wanted to measure displacement while a dynamic random test is on and output i want to read in time and frequency vs displacement format using an accelerometer.

Piezoelectric accelerometer with calibration certificate are available for this purpose.

They Look like This.
