The filters discriminate between signals based on the frequency range, or bandwidth, of the signal.
- Page 29 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. NI 9244 User Manual and Specifications | © National Instruments | 29...

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 9244 with other modules that use master timebases to control sampling, all of the modules must share a single master timebase source. - Page 31 16.667 kS/s, and so on down to 1.613 kS/s, depending on the value of n. When using an external timebase with a frequency other than 12.8 MHz, the NI 9244 has a different set of data rates. The NI 9151 R Series Expansion chassis does not Note support sharing timebases between modules.
