Analog Output Features

An analog output (D/A) subsystem is provided on all DT3000 Series boards except the
DT3002 board, which does not support analog output.

This section describes the following features of the D/A subsystem:

• Analog output resolution

• Analog output channels

• Output ranges and gains

• D/A output clock sources

• Trigger sources

• Analog output conversion modes

• Data formats and transfer

Analog Output Resolution

All DT3000 Series boards (except the DT3002) have a fixed analog output resolution of 12 bits.
The analog output resolution cannot be changed in software.

Analog Output Channels

DT3000 Series boards (except the DT3002) support two analog output channels (DAC0 and
DAC1). Refer to

Chapter 4 starting on page 39

for information on how to wire analog output

signals to the board using the screw terminal panel. Use software to specify the configuration
of the analog output channels as differential.

Within each DAC, the digital data is double buffered to prevent spurious outputs, then output
as an analog signal. Both DACs have a single dedicated timer that latches the digital values
into each DAC. The DACs are initialized to 0 V on power up or reset.

DT3000 Series boards can output data from a single analog output channel or from both
analog output channels. The following subsections describe how to specify the channels.

Specifying a Single Channel

The simplest way to output data to a single analog output channel is to specify the channel for
a single-value analog output operation using software; refer to

page 80

for more information

on single-value operations.

Specifying One or More Channels

You can specify one or both analog output channels in the analog output channel list, either
starting with DAC0 or with DAC1.

Values are output simultaneously to the entries in the channel list.
