The new OMB-DAQ-3000 Series
offers high-speed, multifunction
data acquisition in a low-cost,
portable package. The module
offers synchronous and concurrent
voltage input, temperature input,
waveform output, counter input,
quadrature encoder input, timer
output and digital I/O. Everything
needed to begin acquiring, viewing
and storing data is included with the
OMB-DAQ-3000 Series, including
comprehensive software support.
The OMB-DAQ-3000 features
a 16-bit/1-MHz A/D converter,
16 analog input channels
user- expandable to 64, up to four
16-bit/1-MHz analog outputs,
24 high-speed digital I/O, 2 timer
outputs and four 32-bit counters.
All analog I/O, digital I/O, and
counter/timer I/O can operate
synchronously and simultaneously,
guaranteeing deterministic I/O
among all signal types.
Unique to the OMB-DAQ-3000 is a
low-latency, highly deterministic
control output mode that operates
independent of the PC. In this
mode, digital, analog and timer
outputs can respond to analog,
digital and counter inputs, as fast as
2 µs, at least 1000 times faster than
other products that rely on the PC
for decision making.
Software
Included with the OMB-DAQ-3000
is new DaqView software,
a comprehensive application that
enables set-up, data logging and
real-time data viewing without
requiring any programming skills.

The DaqView software also
includes additional features such
as direct-to-Excel enhancements,
FFT analysis, and statistics.
Also included with the
OMB-DAQ-3000 is a complete
set of drivers and detailed sample
programs for the most popular
programming languages and
software packages. Driver support
includes Visual Basic, C/C++,
LabVIEW and DASYLab. DaqCOM
provides Windows-based
ActiveX/COM-based programming
tools for Microsoft Visual Studio
and Visual Studio.NET.
Analog Input
The OMB-DAQ-3000 has
a 16-bit, 1-MHz A/D coupled
with 16 single-ended inputs,
8 differential analog inputs, or
8 differential thermocouple inputs.
Seven software-programmable
ranges provide inputs from
10V to ±100 mV full scale. Each
channel can be software-configured
for a different range, as well as for
single-ended or differential bipolar
input, or thermocouple input.
The hybrid PGIA on the
OMB-DAQ-3000 is guaranteed
to settle to the specified accuracy
while operating at the full 1
Msample/s rate.
Every analog input on the
OMB-DAQ-3000 or on the
OMB-PDQ30 expansion option can
accept a thermocouple (TC) input.
Built-in cold-junction sensors are
provided for each of the removable
screw-terminal connectors, and any
TC type can be attached to any
channel. When measuring TCs,
the OMB-DAQ-3000 operates
in an over-sample mode, where
multiple readings taken on each TC
channel, digitally filtered, coldjunction compensated and
converted to temperature. As a
result, channels with TCs attached
are measured at a rate 50 Hz to 10
kHz, depending on how much oversampling is selected. In line-cycle
rejection mode, over- sampling
occurs during one cycle of either
50 Hz or 60 Hz, providing a high
level of 50 Hz or 60 Hz rejection.
Analog Channel Expansion
Adding additional analog input
channels for the OMB-DAQ-3000
is easy using the optional
OMB-PDQ30 expansion module.
The OMB-PDQ30 connects to the
OMB-DAQ-3000 by either plugging
directly into the expansion
connector or via a cable
(OMB-CA-96A) if distance
is required between the two units.
The OMB-PDQ30 provides an
additional 48SE/24DE analog
inputs or 24 differential
thermocouple inputs, softwareconfigured on a per- channel basis.
The total channel capacity with a
OMB-PDQ30 attached is 64 singleended or 32 differential inputs.
Synchronous I/O
The OMB-DAQ-3000 can make
analog measurements and read
digital and counter inputs, while
synchronously generating up to four
analog outputs as well as digital
pattern outputs. Digital and counter
inputs do not affect the overall A/D
rate because they use no time slot
in the scanning sequencer.
Input Scanning
The OMB-DAQ-3000 has several
scanning modes to address a
wide variety of applications. A 512location scan buffer can be loaded
by the user with any combination
of analog input channels. All analog
input channels in the scan buffer are
measured sequentially at 1 µs per
channel.
The user can also specify that the
sequence repeat immediately or
repeat after a programmable delay,
from 0 to 19 hours, with 20.83 ns
resolution.
Output Timing
The digital and analog outputs
on the OMB-DAQ-3000 can be
updated asynchronously or
synchronously in several modes.
In asynchronous mode, digital and
analog outputs can be updated
before, during or after an analog
input sequence. The maximum
update rate in this mode is nondeterministic and is entirely
dependent on the PC processor
speed, the operating system and
programming environment.
In synchronous output modes,
outputs can be updated
continuously from the PC or in
response to an input from an analog
channel, digital channel or counter
channel.
When updated from the PC, the
user can specify the rate
at which the output is updated in
20.83 ns intervals. Outputs are
updated synchronously at a
maximum rate of 1 µs.

Model NumberAnalog Inputs Input Ranges Digital I/O Analog Outputs Counter/Timers
The other synchronous method
of output is where either a digital,
analog, or timer output is associated
with any analog, digital or counter.
The state or level of the output is
determined by the level or state of
an associated input.
Triggering
The OMB-DAQ-3000 supports
a full complement of trigger
modes to accommodate
any measurement application.
Calibration
Every range on the OMB-DAQ-3000
is calibrated from the factory using
a digital NIST traceable calibration
method. This method works by
storing a correction factor for each
range on the unit at the time of
calibration.
Included with each OMB-DAQ-3000
is DaqCal sofwtare, an easy-tooperate software package that
allows the users to calibrate their
OMB-DAQ-3000.
Analog Output
(OMB-DAQ-3000
and 3001 Only)
Two or four 16-bit, 1-MHz analog
output channels are built into the
OMB-DAQ-3000 with an output
range from -10 to +10V. The
maximum rate at which analog
outputs can be updated depends on
several factors, including the speed
of the USB port. Typically, with the
A/D operating at full 1 Mreading/s
rates, one analog output can be
updated continuously from PC
memory at 1 MHz, or two analog
outputs at 500 kHz or four analog
outputs at 250 kHz. If waveform
output throughput is critical to your
application, contact OMEGA for the
most recent update on multichannel DAC output rates.
In addition, a program can
asynchronously output a value to
any of the D/As for non-waveform
applications, presuming that the D/A
is not already being used in the
waveform output mode.
Lastly, each of the analog outputs
can be used in a control mode,
where the output level is dependent
on whether an associated analog,
digital or counter input is above or
below a user-specified limit
condition. When used to generate
waveforms, the D/As can be clocked
in several different modes. Each
D/A can be separately selected to
be clocked from one of the
following sources.
Asynchronous
Internal Clock
The on-board programmable clock
can generate updates ranging from
once every 19 hours to 1 MHz,
independent of any acquisition rate.
Synchronous
Internal Clock
The rate of analog output update
can be synchronized to the
acquisition rate derived from 1 MHz
to once every 19 hours.
Asynchronous
External Clock
A user-supplied external input
clock can be used to pace the
D/A, entirely independent of
analog inputs.
TMQSS-125U-12, $26.95
KMQSS-125U-12, $26.95
Synchronous
External Clock
A user-supplied external input clock
can pace both the D/A and the
analog input.
Digital I/O
Twenty-four TTL-level digital I/O
lines are included in the
OMB-DAQ-3000. Digital I/O can be
programmed in 8-bit groups as
either inputs or outputs and they can
be scanned in several modes (see
Input Scanning). Ports programmed
as inputs can be part of the scan
group and scanned along with
analog input channels, or they can
be asynchronously accessed via the
PC at any time, including when a
scanned acquisition is occurring.
Two synchronous modes are
supported when scanned along with
analog inputs. In one of these
modes, digital inputs are scanned at
the start of each scan sequence,
which means the rate at which they
are scanned is dependent on the
number of analog input channels
and the delay period.
Pattern Generation
Two of the 8-bit ports can be used to
generate a 16-bit digital pattern
at up to 1 MHz. The digital pattern
can be read from PC RAM or a file
on the hard disk. Digital pattern
generation is clocked in the same
four modes as was described with
analog output.

OMB-DAQ-3000 Series Block Diagram
Counter Inputs
Four 32-bit counters are built into
the OMB-DAQ-3000. Each will
accept frequency inputs of up to
20 MHz, and each counter channel
can be configured in a variety of
modes, including counter, period,
pulse width, time between edges, or
multi-axis-quadrature encoder. The
counters can concurrently monitor
time periods, frequencies, pulses,
and other event-driven incremental
occurrences from encoders, pulse
generators, limit switches, proximity
switches, and magnetic pick ups.
As with all other inputs to the
OMB-DAQ-3000, the counter inputs
can be read asynchronously under
program control, or synchronously
as part of an analog and digital scan
group based either on an internal
programmable timer or on an
external clock source.
The OMB-DAQ-3000 supports
quadrature encoders with up to
2 billion pulses per revolution,
20 MHz input frequencies, and
x1, x2, x4 count modes. Encoder
input signals must be within
-15 to 15V and the switching
threshold is TTL (1.3V).
Timer Outputs
Two 16-bit timer outputs are built
into the OMB-DAQ-3000, each
capable of generating different
square waves with a programmable
frequency range from 16 Hz to
1 MHz.
