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 digital-to-analog converter
(DAC) channels and/or digital input/output (DIO) channels that are synchronously
updated by a clock source defined by the application.
The daqDacWaveSetClockSource function’s clockSource parameter specifies the clock source to
use for updating all DAC/DIO channels which have been configured for waveform/pattern output. Regardless
of the clock source selected, all channels configured for waveform/pattern output (see
daqDacSetOutputMode
will be synchronously updated upon each update clock pulse.
If using DaqBoard(ISA): If the more than one DAC channel waveform/pattern output is
active, the update frequency for each channel is this rate divided by the total number of
active DAC waveform output channels.
