This laboratory is about the data acquisition which have 2 type of input are analog and Digital input. The program is using DAQ assistant which is a function block in the front panel that can setting all of the input data. We can either sent or acquire data. The important thing is we need to carefully choose the correct running time, sampling mode and type of data acquisition. If we choose the wrong type, it will caused an error such as data distortion or aliasing as you can see from the result of the experiment.
