Output Clock
When in continuous output mode, described on page 19 , you can
update both analog output channels simultaneously using the
internal clock on the KUSB-3100 module.
Using software, specify the clock source for the D/A subsystem as
internal and specify a frequency between 30 Hz to 50 kHz at which to
update the analog output channels.
Note: The output clock frequency that you specify is the frequency
at which both analog output channels are simultaneously updated.
Output Conversion Modes
The KUSB-3100 module supports the following output conversion
modes:
• Single-value output operations, described on this page.
• Continuous output operations, described on page 19 .
Single-Value Operations
Single-value operations are the simplest to use but offer the least
flexibility and efficiency. Use software to specify the analog output
channel, and the value to output from the analog output channel.
Since a single-value operation is not clocked, you cannot specify a
clock source, trigger source, or buffer.
Single-value operations stop automatically when finished; you
cannot stop a single-value operation.
