samples per second (S/s)
The sampling rate ofsample-and-hold circuits and A/D converters is given by the number of samples in a unit of time.
The basic unit is samples per second (S/s). One sample/second corresponds to one sample in one second.
Building on the basic unit, there are kilosamples per second (kS/s), which corresponds to one thousand samples per second, or megasamples per second( MS/s), which is one million samples per second.
