- Page 8 Understanding NI 9229E/9239E Filtering The NI 9229E/9239E uses a combination of analog and digital filtering to provide an accurate representation of in-band signals while rejecting out-of-band signals. The filters discriminate between signals based on the frequency range, or bandwidth, of the signal.

Page 10: Alias-Free Bandwidth
Alias-Free Bandwidth Any signal that appears in the alias-free bandwidth of the NI 9229E/9239E is not an aliased artifact of signals at a higher frequency. The alias-free bandwidth is defined by the ability of the filter to reject frequencies above the stopband frequency and equals the data rate minus the stopband frequency. - Page 11 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 9229E/9239E has a different set of data rates. © National Instruments Corp. and enter...
