NI 9227 Operating Instructions and Specifications

The following equation provides the available data rates of the
NI 9227:

f

s

=

where

n

is any integer from 1 to 31.

However, the data rate must remain within the appropriate data rate
range. Refer to the

Specifications

section for more information

about the data rate range. When using the internal master timebase
of 12.8 MHz, the result is data rates of 50 kS/s, 25 kS/s,
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 9227 has a different set of data rates.

Note

The NI cRIO-9151 R Series Expansion chassis

does not support sharing timebases between modules.
