The NI 9225E analog input channels are floating with respect to earth ground and each other. The incoming analog signal on each channel is conditioned, buffered, and then sampled by a
Each channel provides an independent signal path and ADC, enabling you to sample all three channels simultaneously. Refer to Figure 5 for an illustration of the circuitry for one channel of the NI 9225E.
