In operating a vibration testing system, a table 20 is provided with a plurality of distinct regions 20-1 to 20-4, and each of the plurality of distinct regions is provided with at least one vibrator 24 of the plurality of vibrators and at least one accelerometer 52 of the plurality of accelerometers. Target vibration strengths are set for each region, and the vibrators are operated. Local vibration strength is measured at each distinct region with the corresponding accelerometer. A signal corresponding to each of the measured local vibration strengths is provided to a controller 44. An individual vibrator control signal is calculated for each distinct region based on the corresponding measured local vibration strength and the corresponding target vibration strength. The individual control signals are provided from the controller to control the vibrator(s) of each distinct region to achieve the target vibration strength at each of the distinct table regions.
