Radio and Television Interference
This equipment has been tested and found to comply with CISPR
EN55022 Class A and EN50082-1 (CE) requirements and also with the
limits for a Class A digital device, pursuant to Part 15 of the FCC
Rules. These limits are designed to provide reasonable protection
against harmful interference when the equipment is operated in a
commercial environment. This equipment generates, uses, and can
radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful
interference to radio communications. Operation of this equipment in
a residential area is likely to cause harmful interference, in which case
the user will be required to correct the interference at his own
expense.
Changes or modifications to this equipment not expressly approved
by Data Translation could void your authority to operate the
equipment under Part 15 of the FCC Rules.
Note: This product was verified to meet FCC requirements under
test conditions that included use of shielded cables and connectors
between system components. It is important that you use shielded
cables and connectors to reduce the possibility of causing
interference to radio, television, and other electronic devices.
Canadian Department of Communications Statement
This digital apparatus does not exceed the Class A limits for radio
noise emissions from digital apparatus set out in the Radio
Interference Regulations of the Canadian Department of
Communications.
Le présent appareil numérique n’émet pas de bruits radioélectriques
dépassant les limites applicables aux appareils numériques de la class
A prescrites dans le Règlement sur le brouillage radioélectrique
édicté par le Ministère des Communications du Canada.

Analog Output Features
This section describes the following analog output features of the
DT331, DT332, DT333, and DT334 boards:
•Resolution,
• Analog output channels,
• Ranges and gains,
•Conversionmode,and
• Data format.
Resolution
Table 2 lists the output resolutions supported by the DT331, DT332,
DT333, and DT334 boards. The resolution is fixed foreach board type;
therefore, it cannot be programmed in software.

Board Type Supported Resolution
DT331 12 bits
DT332 12 bits
DT333 16 bits
DT334 16 bits

Analog Output Channels
The DT331 and DT333 boards support four serial, multiplying,
DC-level analog output channels (DAC0 to DAC3) through the D/A
subsystem. The DT332 and DT334 boards support eight serial,
multiplying, DC-level analog output channels (DAC0 to DAC7)
through the D/A subsystem.
Refer to the DT330 Series Getting Started Manual for information on
how to wire analog output signals to the board using the screw
terminal panel. Using software, configure the channel type as
differential.
Within each DAC, the digital data is double-buffered to prevent
spurious outputs, then output as an analog signal. All DACs power
up to a value of 0 V ±10 mV. Resetting the board does not clear the
values in the DACs.
DT331, DT332, DT333, and DT334 boards can output data from a
single analog output channel only. Use software to specify the
channel.
Ranges and Gains
DT331 and DT332 boards support the following rangesfor each DAC:
±10 V (the default), 0 to 10 V, ±5 V, or 0 to 5 V. The DT333 and DT334
boards support the ±10 V range only. Specify the range using
software.
The gain for the D/A subsystem on the DT330 Series boards is
always 1 (the default value).
