Simultaneously Sampled Analog Input Module
In a simultaneously sampled analog input module, each analog input channel has its
own ADC. When the sample clock rises, the ADC of all enabled channels start con-
version simultaneously. The sampled results represent the analog input values at the
same time. Figure 3.10 and Figure 3.11 show the block diagram and acquisition
behavior of this kind of module.
