we got a voice coil type vibration shaker. we use a signal generator and a power amplifier to drive the shaker. we can do some primitive sinusoidal vibration test (with an accelerometer, a oscilloscope). any stone age device we can use to conduct some random vibration, even just with a flat line on PSD ? thanks.
PS. most vib requirement, 5 to 2,000 Hz. RTCA/DO160, MIL-STD-810....
