A question concerning Simultaneous Acquisition using State Machines

[raul20002]

Hello,

I've read some theory about State Machines in Labview and I have the following problem.

I created a simulated USB9233 device and I am interested in the analysis of two signals acquired simultaneously from Channels 0 and 1.

1. I want to acquire two simultaneous sequences of 2048 samples at a rate of 15kHz.

2. I want to plot the sequences and their spectrum.

3. I want to end the process or go back to step 1 and start over with two new sequences.

I've attached my vi. Is it correct? Does it work ok? 

Thank you very much and have a nice day.

Hi raul20002,

I was able to get the VI running using asimulated device.  Is there any reason you want to use a statemachine?  The following code functions the same as your state machine:

Otherwise, the best way to know if the VI is working properly is to use actual hardware with a known signal to verify the measurement.

Hello and thank you for your answer.

I can understand that the code you sent me. However, the reason I wish to understand and work with state machines is the fact that at school, I am required to use use this manner of implementation. I recently looked at a Labview Basics I: Introduction Course Manual. At the end of this book (Lesson 10-5) there are some examples with state machines.

I wanted to see if my vi is correct and if I understood the concept of state machines.

Thank you again.

That looks OK. I will generally include a diagram to illustrate the State Machine to make it easier for people to understand my code.
