Specifying Analog Output Channels
You can output data continuously from one or both analog output
channels using the output channel list. If you want to output data
from one analog output channel continuously, specify either 0
(DAC0) or 1 (DAC1) in the channel output list. If you want to output
data to both analog output channels continuously, specify the output
channel list in the following order: 0, 1.
Then, use software to specify the data flow mode as continuous for
the D/A subsystem; refer to
page 18 for more information on
continuous analog output operations.
Output Resolution
The KUSB-3100 module provides a fixed output resolution of 12 bits.
Note that the resolution is fixed; it cannot be programmed in
software.
Output Ranges and Gains
The KUSB-3100 module provides a fixed output range of ±10 V (the
gain is ignored).
Output Trigger
A trigger is an event that occurs based on a specified set of
conditions. The KUSB-3100 module supports a software trigger for
starting analog output operations. The module starts outputting data
when it receives a software command (trigger).
Use software to specify the trigger source for the D/A subsystem as a
software trigger.
