Hi
I am using analog to digital converter VI. In that VI, I see all parameters except sample rate. An ADC should always come with sample rate like 10KSPS,1MSPS. Can you tell me how to control sample rate of ADC. I have attached snapshot of my code.
Solved! Go to Solution.

I Guess siva is asking about the A to D Converter sampling rate....

And as already been answered, the converter rate is set by the sampling rate of the input signal. Have you looked at how the analog to digital converter actually works? Each and every element of the input waveform is converted. By itself, it is not at all the equivalent of a hardware A/D. The sampling part of an A/D is being done by the simulate signal function.

If number of samples per second is fixed( which is adc sample rate) and if we change the frequency of signal , number of capture points should change.
Example : If frequency of triangle signal is reduced by half, then number of samples captured in one cycle should be double.
Is this way simulated signal VI works/Designed?

The sample rate is not fixed. It is settable on the front panel of the express VI. If you don't change it, yes you are correct about rhe number of points per cycle and this is the expected/designed behavior. Just like if you were using a real DAQ card,

Thank you for the details.
