Data Translation DT9834 Data Sheet
DT9834 Series
High-Performance Multifunction
Data Acquisition USB Modules
■ Simultaneous Subsystem Operation
— Up to 32 SE/16 DI analog input
channels with programmable gains.
— 16-bit A/D and D/A
converters for 500 kHz throughput.
— Four deglitched analog outputs for
waveform generation.
— 16 Digital input lines that can be
clocked synchronously at the
analog input rate, 16 digital output
lines that can be clocked
synchronously at the analog output
rate, and one dynamic digital output line. One bank of eight digital
input lines also supports
interrupt-on-change.
— Five 32-bit counter/timer channels
that can be clocked synchronously
at the analog input rate and that
support event counting, frequency
measurement, period measure-
ment, pulse width measurement,
continuous pulse output, one-shot,
repetitive one-shot, and up/down
counting operations.
■ Flexible Clocking and Triggering
— Independent clock sources (internal
and external TTL-level) for pacing
analog inputs and analog outputs.
— Independent trigger sources
(internal, external TTL-level, and
external analog threshold) for
starting analog input and analog
output operations.
— Flexible acquisition modes (single
value, continuous, and triggered
scan) for input operations, and
flexible output modes (single value,
continuous, and waveform
generation) for output operations.
■ 500 Volt Galvanic Isolation
Prevent ground loops to maximize
analog signal integrity and protect
your computer.
■ High-Speed USB 2.0
Transfer data at rates up to 480 Mbps.
■ Many Software Choices
The Data Acquisition OMNI CD is
shipped with the module and includes
Ready-to-Measure™ software, DTOpen Layers device drivers for
Windows 2000/XP, an evaluation version of DT Measure Foundry, and
more.
Figure 2. The DT9834 Series provides USB 2.0 multifunction modules for simultaneous
A/D, D/A, DIO, and C/T subsystem operation. This detailed block diagram shows the relationship of each subsystem and the control signals used in the series. For flexible, costeffective solutions, you can choose the number of analog I/O channels and the
the packaging configuration that suits your application.
