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....

Of course I can. I can do anything. I can do absolutely anything. I'm an expert!

If you want cheap, you could possibly use a computer sound card output and run that into your amplifier, or any sort of arbitrary waveform generator like: But the latter is just a higher frequency version of a sound card; it's just the latter will probably look less hobby-shop to a customer.

someone can write me couple lines in VB to have such random signal (5 to 2,000 Hz) to sound card ?
most cheap waveform generators do not limit to 2,000 Hz, i do not know how to insert a low pass filter.
thanks.
