NI 9225 Operating Instructions and Specifications
share a single master timebase source. Refer to the software help
for information about configuring the master timebase source for
the NI 9225. Visit

The following equation provides the available data rates of the
NI 9225:

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 9225 has a different set of data rates.
Note
The cRIO-9151 R Series Expansion chassis does
not support sharing timebases between modules.
