I am working with a volume velocity acoustic source to measure FRF’s on a vehicle and I need to generate a band limited (10 Hz – 1000 Hz) burst random 5V pink noise. However, spectral testing does not allow me to limit spectral content of the output signal when pink noise is selected. Can you help me find a work around?
Solved! Go to Solution.
Here are two options
Option #1 - Use MIMO FRF Testing
Option #2 - Q Amplifier
Additionally if you have a new Q source amplifier(Q-AMP) it has a high pass filter which can be used to limit the band of the pink noise (see attachment).
