DT9834 Series

High-Performance Multifunction
USB Data Acquisition Modules
Overview
The DT9834 is a series of high-speed, high-performance
USB data acquisition (DAQ) modules. These USB DAQ
modules are available in a variety of configurations,allowing you to choose the number of analog I/Ochannels and packaging that suits your application.
DT9834 Series modules are available in two configurations:
BNC connection box and OEM embedded version.

The DT9834 Series combines the functionality ofmultiple boards in a single USB 2.0 module to provide
simultaneous analog input, analog output, digital I/O,
and counter/timer operations. Available in a number ofconfigurations, the DT9834 Series provides maximum
flexibility. All modules feature 16 digital input lines,
16 digital output lines, and 5 counter/timer channels.

High-Speed, High-Resolution Analog Inputs

High-Speed Digital I/O Lines

DT9834 Series modules are available in two analog
input channel configurations: 16 SE/8 DIFF or 16 SE
inputs, or no analog inputs. All analog input signals are
multiplexed to a single analog-to-digital converter. Allmodules feature sample rates up to 500 kS/s with 16-bit
resolution.

DT9834 Series modules feature 16 digital input lines and
16 digital output lines. The first eight digital input lines
can also be used for interrupt on change. You can read
all the digital input lines simultaneously with the analog
input channels at the A/D clock rate. The digital input
lines can also be clocked separately as the only channel inthe channel-gain list at up to 500 kS/second.

Four programmable gains (1, 2, 4, and 8) are provided tosupport input signal ranges of +/- 10 V, +/-5 V, +/-2.5 V,and +/-1.25 V. By configuring each analog input channel
for the input range that you want, you can connect many
output transducers directly to the module.

Flexible Clocks and Triggers
For maximum flexibility, all DT9834 Series modules
provide independent clocks and triggers for the A/Dand D/A subsystems. This allows you to trigger andclock the analog output subsystem synchronously with,or independent of, the analog input subsystem. Eachsubsystem supports an internal clock and external clock
input, as well as the following trigger types: softwarecommand, analog threshold, and external digital input
trigger.

Flexible Acquisition Modes
Using the DT9834 Series, you can acquire a single sample
from a single analog input channel or multiple samples
from multiple analog input channels. A 1024-location
channel-gain list gives you the flexibility to sample nonsequential analog input channels, analog input channels
with different gains, and digital inputs and counter/timer
channels with the analog input channels you want at theA/D sample rate.

Multifunction Counter/Timers
All DT9834 Series modules feature five 32-bit user
counter/timers. If you wish, you can read the valueof the counter/timer channels with the analog input
channels and digital input lines at the A/D clock rate. The
following counter/timer functions are supported: event
counting, edge-to-edge measurement, continuous edgeto-edge measurement (for determining the frequency
and period width of a signal), continuous pulse output,
one-shot, repetitive one-shot, and up/down counting
operations. To read the frequency period of a signal aspart of the analog input data stream, use continuousedge-to-edge measurement mode.

DT9834 Series modules provide two ways to cycle
through the channel-gain list:• Continuous scan mode
• Triggered scan mode
High-Speed, High-Resolution Analog Outputs
DT9834 Series modules are available in two analog
output channel configurations: 4 deglitched analog
output channels, or no analog output channels. Eachanalog output channel has its own digital-to-analog
converter and provides an output signal range of +/- 10V. You can achieve a maximum update rate of 500 kS/
second with 16-bit resolution.

Programmable gates, clocks, and output signals are alsosupported.

Flexible Output Modes
Using the DT9834 Series, you can output a single value
from a single analog output channel or multiple values
from multiple analog output channels. An outputchannel list gives you the flexibility of updating only theanalog output channels you want or updating the digitaloutput lines with specified analog output channels at theD/A clock rate. You can update analog output channels
at up to 500 kS/s.

Flexible Packaging Configurations
DT9834 Series modules are available in two packaging
configurations: a BNC connection box or an OEM
embedded version. The BNC connection box is available
with 16 SE channels, 4 BNCs for connecting analog
outputs, and 4 BNCs for connecting external clocks andtriggers.
The BNC configuration ships with a +5 V galvanicallyisolated power supply and power cable (EP361), USB 2.0
cable, and Data Acquisition OMNI CD.
The OEM configuration, ideal for embedding in test
systems, provides all the functionality of the DT9834
Series in PC-board form. This configuration ships with a
USB 2.0 cable and Data Acquisition OMNI CD.

QuickDAQ ships free-of-charge and allows you to get up andrunning quickly.

Computers are susceptible to ground-spikes through any
external port. These spikes can cause system crashes andmay even cause permanent damage to your computer.
DT9834 Series modules feature 500 Volts of galvanic
isolation to protect your computer from ground-spikes
and to ensure a reliable stream of data.

Cross-Series Compatibility
Virtually all Data Translation data acquisition modules
are compatible with the DT-Open Layers® software
standard. This means any application developed with
one of Data Translation’s software products can easily be
upgrade to a new Data Translation module with little tono reprogramming needed.

QuickDAQ
QuickDAQ allows you to acquire and display from all
Data Translation USB and Ethernet data acquisition
devices that support analog input streaming. Combine
QuickDAQ with Data Translation hardware to acquiredata, record data to disk, display the results in both aplot and digital display, and read a recorded data file.
Be productive right out of the box with this powerfuldata logging software. Data can be exported to otherapplications like Microsoft Excel® and The Mathworks
MATLAB® for more advanced analysis. Two additional
options can be purchased to add FFT analysis capabilities
to the base package.
