What I can’t understand is the difference between the continuous acquisitions and the N sample ones.
In conclusion: My algorithm process data sample by sample. What is the best setting to use in order to measure and send the signal to my algorithm in real time and point by point (sample by sample) and not as a group of 1000 samples?
I have attached both programms.
Thanks in advance.

What Dennis has posted is some good advice for data acquisition. It seems that the best method for you to apply would be to use Point by Point acquisition as Dennis mentioned. This method transfers a single point from the device to LabVIEW memory upon each read to the device. It seems that this is the methodology which you are trying to achieve. But this method does greatly increase the CPU overhead and so, depending on the specifications of your PC, could affect your system performance.
I have included a couple of links below to out knowledgebase, which provide some detailed articles on this type of acquisition. You can also find a good example VI by going to Help>>Find Examples>>hardware Input & Output>>DaqMX>>Analog Measurements>>Voltage>>Cont Acq&Graph Voltage-Single Point Optimization.
