∙Sampling Rate: must be an integer with a value of 2 or greater. This is the ratio of the output sample period to the input, and is essentially a sample rate multiplier. For example, a ratio of 2 indicates a doubling of the input sample rate. If a
∙Copy Samples: allows you to choose what to do with the additional samples produced by the increased clock rate. By selecting Copy Samples, the same sample will be duplicated (copied) during the extra sample times. If this checkbox is not selected, the additional samples are zero.
