I need to know whether ADcmXL3921 samples all three axis simultaneously or sequentially . Observed from its characterization in MTC mode, it takes 60ms to record 4K sample of each axis. It implies that the acquisition at full rate of 220KSPS is done one after the other for all three axis. If this is not true , the capture time of one event should have been 20ms. What is the expert opinion for AD officials ?
