Hi Shyam,
Were you able to verify that your edge count is counting at the correct rate? You explain that the frequency measurement returns random values, but are they within a certain range? Maybe you could post some of the data that is returned. If your signal is noisy your measured frequency could appear to be very different than your expected frequency. What is generating the signal you are measuring? When you perform an edge count measurement your signal should be connected to the counter source, while in a frequency measurement your signal should be connected to the counter gate.
