Understanding NI 9234 Data Rates
The frequency of a master timebase (f
M
) controls the data rate (f
s
)
of the NI 9234. The NI 9234 includes an internal master timebase
with a frequency of 13.1072 MHz, but the module also can accept
an external master timebase or export its own master timebase. To
synchronize the data rate of an NI 9234 with other modules that use
master timebases to control sampling, all of the modules must
share a single master timebase source. Refer to the software help
for information about configuring the master timebase source for
the NI 9234. Visit

The following equation provides the available data rates of the
NI 9234:

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
