Understanding NI 9234 Data Rates
The freq
u
ency of a master timebase (
f
M
) controls the data rate (
f
s
)
of the NI 9234. The NI 9234 incl
u
des an internal master timebase
with a freq
u
ency of 13.1072 MHz, b
u
t the mod
u
le also can accept
an external master timebase or export its own master timebase. To
synchronize the data rate of an NI 9234 with other mod
u
les that
u
se
master timebases to control sampling, all of the mod
u
les m
u
st
share a single master timebase so
u
rce. Refer to the software help
for information abo
