Function Usage
The term waveform/pattern output is used extensively throughout the entries for the
functions of the form daqDac…. This refers to an analog waveform output modes and/or
digital pattern output modes. These terms describe output to DAC and/or digital output
channels that are synchronously updated by a clock source defined by the application.
The trigger event must first have been configured for software triggering with the daqDacWaveSetTrig
function prior to calling this function, and the trigger source must have been set to DdtsSoftware. Once
issued, the waveform/pattern output operation will begin; the updating of all channels configured for
waveform/pattern output will also begin. The deviceType and chan parameters must correspond with a
channel that has been configured for waveform/pattern output using the daqDacSetOutputMode function.
