Analog Output Timing Events specify how the hardware paces or clocks
the sample output. DriverLINX uses the Timing Event to program when
the DDA-08/16 writes the next analog output sample to the DACs.
The DDA-08/16 allows applications to specify the analog channels using
three techniques: Start Channel, to write analog data to a single channel;
Start/Stop Channel Range, to write analog data to a consecutive range of
channels; and Channel List, to write analog data to a list of channels. The
DDA-08/16 board has individual gain switches for each channel.
DriverLINX uses a gain code of zero for all switch settings.
DriverLINX supports both single-value analog output and buffered
analog output.
●
For single-value output
— Specify the Number of buffers as
0
and
the number of
Samples
as
1
. Use Polled mode and store the data in
the
ioValue
Service Request property.
●
For buffered output
—
Specify the Number of buffers from
1
to
256
and the number of
Samples
as desired.
An individual DriverLINX buffer may have any size as long as the buffer
length holds an integral number of channel scans.
The DDA-08/16 offers both bipolar and unipolar analog output ranges.

Analog I/O Panel
The DriverLINX Analog I/O Panel is an application that demonstrates
analog input/output using DriverLINX. With the Analog I/O Panel you
can:
●
Analyze analog signals using the simulated two-channel
Oscilloscope.
●
Measure analog voltages using the simulated Digital Volt Meter.
●
Generate Sine, Square, and Triangle waves using the SST Signal
Generator.
●
Output DC Level voltages using the Level Control.
