How to check the sampling rate and frequency of voltage signal obtained from NI cRIO 9068

[Sugandh]

Hello,

I am using LabVIEW 2017 with cRIO 9068 with module NI 9242. I want to measure sampling rate and frequency of the input voltage signal. 

How can I check these?

Can you say a bit more about what you are trying to accomplish? If you are measuring a signal you are setting the sample rate. What does the input waveform look like? That can have a huge impact on how the extract frequency. What anti-aliasing filters are you using?

I am using NI 9068 with NI 9242 voltage input module. Input is 50 Hz sinusoidal voltage from a power port, and output also 50 Hz Sinusoidal voltage. I want to store the one cycle samples(there are how many samples in one cycle of 50 Hz sinusoidal wave). After storing these samples I want to Estimate phase angle,  magnitude and frequency from these samples.

I am sending my VI can you suggest anything.
