High Performance, Isolated
Simultaneous USB Data Acquisition
Overview
The DT9832 and DT9836 are a series of high-speed, highperformance USB data acquisition modules that provide
simultaneous analog input operation at up to 2.0 MS/s
per channel. Each analog input has its own A/D converter
to eliminate phase shift between channels and to allow
you to correlate measurements at the exact same instantin time. Each USB DAQ module features three quadrature
decoders for measuring absolute and relative position
and for detecting rotational speed.

The DT9836, shown in BNC connection box, provides
simultaneous analog inputs at up to 225 kS/s per channel.

Synchronous Operation

The DT9836 and DT9832 Series provides USB 2.0
multifunction modules for simultaneous operation ofanalog input, analog output, digital I/O, and counter/timer
subsystems.

All functions of the data acquisition modules (A/D,D/A, DIO, counter/timers, and quadrature encoders)can be simultaneously triggered internally or externally.
The data can then be streamed synchronously to hostmemory. This can be done via external trigger or by theinternal clock of the module. The synchronous operation
allows all I/O data to be processed and correlated for all
inputs and outputs. This is very valuable in determining
the response across a device-under-test (DUT) to stimuli
at the same exact instant.

Selection Criteria: Nyquist and Bandwidth Limits Determine Model Choices
Each model has been designed to accurately measure higher bandwidth signal components. To accurately measure
16-bit accuracy, the front-end input amplifier has a bandwidth of ten times the Nyquist limit. Below are examples ofthese design characteristics for each board.

Closely Matched Analog Inputs

High-Speed, High-Resolution Analog Outputs

The isolated analog inputs of the DT9832 and DT9836
Series have been designed to match each other withhigh precision. Each input has its own separate highimpedance 16-bit A/D converter. The impedance has
been carefully matched for each of the inputs so that
one looks exactly like the other. The data acquisitionboard has 12-layers in its make-up to adequately shieldand protect each signal path etch from the high speedtransitions of the digital lines. The slightest mismatch
would result in DC and AC errors in measurement whentrying to correlate readings at the same instant in time.

There are 2 simultaneous 16-bit analog outputs, and anoption for 4 outputs, on the DT9836 Series, composedof separate high speed, deglitched, waveform D/Aconverters. This design allows highly accurate arbitrary
waveforms to be generated at throughput speeds of
500 kS/s each. Standard waveforms such as sine, triangle,and square waves are easily produced by loading theoutput memory and triggering them synchronously
or separately. Great care has been used in design tominimize the glitch energy for any major or minor carry.
This results in extremely smooth waveforms.

Flexible Output Modes
Using the DT9832 and DT9836 series, you can output
a single value from a single analog output channel ormultiple values from multiple analog output channels.
An output channel list gives you the flexibility of
updating only the analog output channels you want or
updating the digital output lines with specified analog
output channels at the D/A clock rate. You can update
analog output channels at up to 500 kS/s.
Both Series feature the following output modes:• Continuous output mode — Choose this mode if
you want to accurately control the period between
conversions of individual output channels in theoutput channel list.
• Waveform mode — Use this mode if you want tooutput waveforms repetitively from an output
FIFO on the module, minimizing communication
overhead with the host computer. If you specify only
one channel in the output-channel list, you can loada waveform containing up to 128 kS into the output
FIFO. If you specify all the analog output channels
and the digital output lines in the output-channel
list, you can load a waveform containing up to 24kS into the output FIFO. Using waveform mode, youcan update multiple channels at up to 500 kS/s.

The DT9836 Series features 6 or 12 independent, successiveapproximation A/D converters with track-and-hold circuitry.
Each converter uses a common clock and trigger for
simultaneous sample of all analog inputs at 225 kS/s perchannel. The DT9832 Series features 2 or 4 simultaneous A/Dconverters with sample rates up to 2.0 MS/s.

High-Speed Digital I/O Lines
The DT9832 and DT9836 Series modules feature 32
digital I/O lines dedicated as 16 in and 16 out. The firsteight 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 theA/D clock rate. The digital input lines can also be clocked
separately as the only channel in the channel-gain list atup to 225 kHz on the DT9836, 1.25 MHz on the DT9832,
and 2.0 MHz on the DT9832A.

The SFDR plots on page 4 give the best indicationof the match of these DC and AC characteristics. The AC
dynamic performance at high switching speeds for all
channels shows overall accuracy to be better than 13.6
bits. This is worst case with all errors shown in the FFTENOB plot. This performance is beyond any other dataacquisition system available.

For digital output operations, you can update all thedigital output lines with the analog output channels atthe D/A output clock rate.

Note: Continuous digital output operations are notsupported on modules that do not have analog output
channels.

All lines are EMI protected to minimize interference fromtransient signals.

Multifunction Counter/Timers
All DT9832 and DT9836 Series modules feature two 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, up/down counting, frequency measurement,edge-to-edge measurement, continuous edge-to-edge
measurement, rate generation, one-shot, and repetitive
one-shot.

A quadrature decoder takes the output signals (A, B, andIndex) for the quadrature encoder as inputs and converts
these signals into a numerical value that can be used todetermine position, distance, velocity, and other functions.

±500 V Galvanic Isolation Protects Your Data
Computers are susceptible to ground-spikes through any
external port. These spikes can cause system crashes andmay even cause permanent damage to your computer.
These modules feature ±500 Volts of galvanic isolation toprotect your computer from ground-spikes and to ensurea reliable stream of data.

Quadrature Encoder
The quadrature encoder module contains three
quadrature encoders which allow simultaneous decodingof three quadrature encoded inputs. The quadrature
decoders may be used to provide relative or absolute
position or, by calculating the difference between
samples, the rotational speed. Each quadrature decoder
supports A, B, and Index inputs. The index input may be
used to zero out the positional count and the A and B
input relationships are used to increment or decrement
the positional count.

EMI and ESD Design Criteria
The DT9832 and DT9836 Series has been designed toperform with the lowest noise characteristics. Damping
resistors in series with every I/O line minimize ringing
and EMI and provide current limits that protect against
transient signals.

Each encoder features a digital input filter that isprogrammable from 27 ns to 7 μs for the DT9836 Series
and from 20 ns to 5 μs for the DT9832 Series. This uniquefiltering capability helps remove ringing edges andunwanted noise.

Flexible Packaging Configurations
The DT9832 and DT9836 Series modules are available intwo packaging configurations: a BNC connection box
and an OEM embedded version. The BNC configurations
are enclosed in metal boxes with standard BNC and DSUB
connectors, 2 BNCs for connecting analog outputs, and
4 BNCs for connecting external clocks and triggers. The
BNC configuration ships with a +5 V galvanically isolated
power supply and power cable, USB 2.0 cable, and Data
Acquisition OMNI CD.

Flexible Clocks and Triggers
For maximum flexibility, all DT9832 and DT9836 Series
modules provide independent clocks and triggers for theA/D and 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 inputtrigger.

The OEM configuration, ideal for embedding in test
systems, provides all the functionality of the DT9832 andDT9836 Series in PC-board form. This configuration ships
with a USB 2.0 cable and Data Acquisition OMNI CD.

PowerCross-Series Compatibility

The BNC connection box option includes a separate +5 V
power supply and power cable for quick setup. OEMs canpurchase these options separately as EP361. A secondary
power connector is also provided for OEMs to allow
custom power wiring.

Virtually all Data Translation data acquisition modules
are compatible with the DT-Open Layers for .NETClass Library. This means that if your application wasdeveloped with one of Data Translation’s software
products, you can easily upgrade to a new Data
Translation board. Little or no reprogramming is needed.
