Stopband
The filter significantly attenuates all signals above the stopband frequency. The primary goal of the filter is to prevent aliasing. Therefore, the stopband frequency scales precisely with the data rate. The stopband rejection is the minimum amount of attenuation applied by the filter to all signals with frequencies within the stopband.
Alias-Free Bandwidth
Any signal that appears in the
NI 9225E is not an aliased artifact of signals at a higher frequency. The
Understanding NI 9225E Data Rates
The frequency of a master timebase (fM) controls the data rate (fs) of the NI 9225E. The NI 9225E includes an internal master timebase with a frequency of 12.8 MHz, but the module also can accept an external master timebase or export its own master timebase. To synchronize the data rate of an NI 9225E with other modules that use master timebases to control sampling, all of the
