How to check the sample rate ?

I'm interfacing labview with arduino. My aim is to get the sampling rate as 10 KHz/sec. How do i check the current sampling rate at which my signal is being sampled? I am getting the output and everything but don't know the current sampling rate. Kindly help me.

Thank you

It is not possible to sample at 10kHz using serial communication with an Arduino (e.g. using LIFA).  In fact, it is barely possible to sample at 10kHz with just the Arduino alone (with the standard setup).

If you need to sample that fast for your application, you should obtain a device that is designed to sample that fast.  For example, the NI USB-6000 can sample at 10kHz.

Thats fine but how do you check the current sampling rate ?

You can get the loop rate like this.

Here is my VI (Hops its clear)

I have added case structure to change my analog pins and do different tasks at each analog pin. So how do I check the sampling rate in this VI. I am using arduino microcontroller

That is the same VI that you posted originally.  See my response above.
