NI 9237 Operating Instructions and Specifications 20 ni.com
The following equation provides the available data rates of the
NI 9237:
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, 16.67 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 9237 has a different set of data rates.
Note The cRIO-9151 R Series Expansion chassis does
not support sharing timebases between modules.
Sleep Mode
This module supports a low-power sleep mode. Support for sleep
mode at the system level depends on the chassis that the module is
plugged into. Refer to the chassis manual for information about
