NI 9229/9239. You can connect ground-referenced or floating signal sources to the NI 9229/9239. Connect the positive signal of the signal source to the AI+ terminal or connector, and connect the negative signal of the signal source to the AI– terminal or connector. If you make a ground-referenced connection between the signal source and the NI 9229/9239, make sure the voltage on the AI+ and AI–...

Wiring for High-Vibration Applications If an application is subject to high vibration, National Instruments recommends that you either use ferrules to terminate wires to the detachable screw-terminal connector or use the NI 9971 backshell kit to protect the connections. Refer to Figure 6 for an illustration of using ferrules.

The small amount of variation in gain with respect to frequency is called the passband flatness. The digital filters of the NI 9229/9239 adjust the frequency range of the passband to match the data rate. Therefore, the amount of gain or attenuation at a given frequency depends on the data rate.

Alias-Free Bandwidth Any signal that appears in the alias-free bandwidth of the NI 9229/9239 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.

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 9229/9239 has a different set of data rates. The cRIO-9151 R Series Expansion chassis does Note not support sharing timebases between modules.
