AO Sample Clock Timebase is not available as an output on the
I/O connector.
You might use AO Sample Clock Timebase if you want to use an external
sample clock signal, but need to divide the signal down. If you want to use
an external sample clock signal, but do not need to divide the signal, then
you should use AO Sample Clock rather than AO Sample Clock Timebase.
Getting Started with AO Applications in Software
You can use a USB-621x device in the following analog output
applications:
•
Single-point (on-demand) generation
•
Finite generation
•
Continuous generation
•
Waveform generation
You can perform these generations through programmed I/O or USB Signal
Stream data transfer mechanisms. Some of the applications also use start
triggers and pause triggers.
Note
For more information about programming analog output applications and triggers in
software, refer to the NI-DAQmx Help or the LabVIEW Help in version 8.0 or later.
