AO Sample Clock Timebase is not available as an o
u
tp
u
t on the
I/O connector.
Yo
u
might
u
se AO Sample Clock Timebase if yo
u
want to
u
se an external
sample clock signal, b
u
t need to divide the signal down. If yo
u
want to
u
se
an external sample clock signal, b
u
t do not need to divide the signal, then
yo
u
sho
u
ld
u
se AO Sample Clock rather than AO Sample Clock Timebase.
Getting Started with AO Applications in Software
Yo
u
can
u
se a USB-621
x
device in the following analog o
u
tp
u
t
applications:
•
Single-point (on-demand) generation
•
Finite generation
•
Contin
u
o
u
s generation
•
Waveform generation
Yo
u
can perform these generations thro
u
gh programmed I/O or USB Signal
Stream data transfer mechanisms. Some of the applications also
u
se start
triggers and pa
u
se triggers.
Note
For more information abo

t applications and triggers in
software, refer to the
NI-DAQmx Help
or the
LabVIEW Help
in version 8.0 or later.
