The new OMB-DAQBOARD-3000
Series comprises of highperformance PCI boards offering
16-bit/1-MHz multifunction
synchronous I/O at very competitive
prices. This is accomplished by
incorporating a high level of
integration, while focusing on
features that provide valuable
benefits to users.
The new OMB-DAQBOARD-3000
Series 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 timing
among all signal types. Unique to the
OMB-DAQBOARD-3000 Series is a
high-speed, low-latency, highly
deterministic control output mode
that operates independent of the
PC. In this mode both digital and
analog outputs can respond to
analog, digital, and counter inputs as
fast as 2 µs; at least 1000 times
faster than most other boards that
rely on the PC for decision making.
Other Hardware Features Include:
• Encoder measurements up to
20 MHz, including Z-channel
zeroing
• Frequency and pulse-width
measurements with 20.83 ns
resolution

Signal Connections
One 68-pin connector provides
access to the 16SE/8DE analog
input channels, 24 digital I/O lines,
6 counter/timer channels, and up to
4 analog outputs on each
OMB-DAQBOARD-3000 Series board.
An externally accessible HDMI
connector is also provided on the
OMB-DAQBOARD-3000 Series,
enabling a simple connection for the
optional OMB-OMB-PDQ30 analog
channel expansion module.
In addition to standard screw-terminal
options for the OMB-DAQBOARD3000 Series, the OMB-DBK215
BNC connection module can be
used to provide screw-terminal
access to all I/O, plus 16 BNC
connectors that can be user
configured.
Analog Input
The OMB-DAQBOARD-3000 Series
has a 16-bit, 1-MHz A/D coupled with
16 single-ended or 8 differential
analog inputs. Seven softwareprogrammable ranges provide
inputs from ±10 V to ±100 mV full
scale (single-ended ±10 V range on
OMB-DAQBOARD-3006). Each
channel can be software-configured
for a different range, as well as for
single-ended or differential bipolar
input. The hybrid PGIA on the
OMB-DAQBOARD-3000 Series is
guaranteed to settle to the specified
accuracy while operating at the full
1 Msample/s rate.

The OMB-DBK215 provides 16 BNC inputs or

Analog Channel Expansion
Adding additional analog input channels
for the OMB-DAQBOARD-3000
Series is easy using the optional
OMB-PDQ30 expansion module.
The OMB-PDQ30 connects to the
OMB-DAQBOARD-3000 Series
card via an OMB-CA-266-3
cable and does not occupy
a PCI slot. The OMB-PDQ30
provides an additional
48SE/24DE analog inputs or 24
thermocouple inputs, software
configured on a per-channel basis.
The total channel capacity with an
OMB-PDQ30 attached is 64 singleended or 32 differential inputs. The
measurement speed of OMB-PDQ30
channels is the same 1 Msample/s
as with on-board channels.
When configured to measure
thermocouple channels, the system
sample rate is 10 kHz per channel.
This reduction in sample rate
ensures that temperature
measurements are accurate,
low noise, and stable.
The OMB-DAQBOARD-3000
Series also
supports up
to 4 boards
installed into
one PC,
effectively
quadrupling the
number
of channels that can
be attached to one PC.
D1-2
The OMB-TB-100, termination board with
screw terminals, provides access to all
OMB-DAQBOARD-3000 Series I/O. The OMB-TB-100
can be panel mounted or 19” rack mounted using
optional OMB-RACK3 mounting kit.
Synchronous I/O
The OMB-DAQBOARD-3000 Series
can make analog measurements
and read digital and counter inputs,
while synchronously generating up
to 4 analog outputs as well as
digital pattern outputs. Additionally,
digital and counter inputs do not
affect the overall A/D rate because
they use no time slot in the
scanning sequencer.
For example, one analog input
channel can be scanned at the full
1-MHz A/D rate along with digital
and counter input channels. The 1MHz A/D rate is unaffected by the
additional digital and counter
channels. Many other data
acquisition boards provide no
capability to scan digital/counter
channels along with analog
channels, in which case digital and
counter channels must be read
asynchronously, which leads to a
non-deterministic collection of data.

The OMB-DAQBOARD-3000 has
several scanning modes to address
a wide variety of applications. A
512 location 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. For example, in the
fastest mode, with a 0 delay, a
single analog channel can be
scanned continuously at
1 Msamples/s; two analog channels
can be scanned at 500 Ksamples/s
each; 16 analog input channels can
be scanned at 62.5 Ksamples/s.
OMB-DAQBOARD-3000 digital
inputs and counter inputs can be
read in several modes. First, via
software the digital inputs or
counter inputs can be read
asynchronously at any time before,
during, or after an analog input scan
sequence. This mode is not
deterministic as to exactly when the
digital or counter input was read
relative to an analog input channel.
In either of the two synchronous
modes, the digital inputs and/or
counter inputs are read with
deterministic time correlation to the
analog inputs. In the once-per-scan
mode, all of the enabled digital
inputs and counter inputs are read
during the first analog
measurement of an
analog input scan
sequence. The
advantage of this
mode is that the digital
and counter inputs do
not occupy an analog
input time slot
and therefore do not
reduce the
available bandwidth
for making analog
input measurements.
For example, assume
all 24 bits of digital
input are enabled, all
four 32-bit counters
are enabled, and eight channels
of analog inputs are in the scan
sequence at the full 1 µs/channel
rate. At the beginning of each
analog input scan sequence, which
would be 8 µs in total duration, all
digital inputs and counter inputs will
be measured and sent to the PC
during the first µs of the analog
scan sequence.
In the other synchronous mode,
digital inputs are scanned every
time an analog input channel is
scanned. For example, if eight
analog inputs are scanned at 1 µs
per channel continuously, and 24
bits of digital inputs are enabled,
then the 24 bits of digital inputs will
be scanned at 24 bits per 1 µs. If
counters are enabled in this mode,
they will be scanned at once per
scan, in the same manner as in
the prior example.

Output Timing
The digital and analog outputs on
the OMB-DAQBOARD-3000 can be
updated asynchronously or
synchronously in several modes.
In the asynchronous mode, digital
and analog outputs can be updated
at any time before, during, or after
an analog input sequence. The
maximum update rate in this mode is
non-deterministic and is entirely
dependent on the PC processor
speed, the operating system, and
the programming environment.
In the synchronous output modes,
the outputs can be updated directly
from memory in the PC, or as the
direct result of an input from either
an analog channel, digital channel,
or counter channel. When updated
from memory in the PC (via DMA),
the rate by which the output can be
specified in 20.83 ns intervals, and
all outputs can be updated
synchronously at a maximum rate
of 1 µs. For example, all four 16-bit
analog outputs can be generating
different waveforms from PC
memory with a 1 µs per channel
update rate, while up to 16 bits of
digital pattern could be generated
from PC memory concurrently at
the 1 µs per 16-bit update rate.
Outputs can also be specified to
update concurrently with inputs, so
there is an exact timing correlation
between inputs and outputs.

ANALOG INPUT AND
MULTI-FUNCTION CARDS
The other synchronous method of
output control is where an output,
either digital or analog, is
associated with any input—analog,
digital, or counter.
D1-3
OMB-DAQBOARD-3000,
attached to an
OMB-DBK215 BNC
and screw-terminal
module.
The state or level of the output is
determined by the level or state of
an associated input. For example, a
digital output could be programmed
to be a logic 1 when an analog input
exceeds a certain value, or when a
frequency input exceeds a certain
rate. In addition, hysteresis can be
programmed for each limit to
ensure the output is stable near the
transition point. Up to 8 digital
outputs and 4 analog outputs can
be programmed to respond to any
analog, digital, or counter input.
When analog or digital outputs are
used in this mode, the user can
specify two output values,
determined by whether the input is
above or below the limit.
The slowest rate at which an analog
output can respond to an input is
4 µs plus the time period of a scan
sequence. For example, if
4 channels of analog input are
scanned continuously at 4 µs per
scan, then the maximum latency
between an analog input satisfying
a limit, and the output responding,
is 4 + 4 or 8 µs max. The worst-case
response time can also be
improved in several ways.
For example, if a digital output is
correlated to a digital input, then the
worst-case latency can be reduced
to 2 µs total if all digital inputs are
scanned at the 1 µs rate without a
delay period at the end of each scan.
In addition, an output status
channel can be specified in the
input scan sequence buffer so that
users can correlate output state
changes to their respective input
channels within their data buffers
and files. Adding the status channel
takes no additional scan time and
has no effect on the overall
acquisition rate. The status channel
can also be read asynchronously at
any time during an acquisition for
monitoring of the control outputs.
The advantage of this mode is that
the response time can be in the
range of 2 to 20 µs, vs. 1000 or
more microseconds when using
other suppliers’ boards.
Triggering
The OMB-DAQBOARD-3000 Series
supports a full complement of
trigger modes to accommodate any
measurement situation.
Hardware Analog Triggering. The
OMB-DAQBOARD-3000 Series
uses true analog triggering,
whereby the trigger level
programmed by the user sets an
analog DAC, which is then
compared in hardware to the analog
input level on the selected channel.
The result is analog trigger latency
that is guaranteed to be less than
1 µs, significantly shorter than most
data acquisition boards. Any analog
channel can be selected as the trigger
channel, including OMB-PDQ30
expansion channels. The user can
program both the trigger level, as
well as the edge (rising or falling)
and hysteresis.
Digital Triggering. A separate
digital trigger input line is provided,
allowing TTL-level triggering with
latencies guaranteed to be less
than 1 µs. Both the logic levels
(1 or 0), as well as the edge (rising
or falling), can be programmed for
the discrete digital trigger input.
Pattern Triggering. The user can
specify a 16-bit digital pattern to
trigger an acquisition, including the
ability to mask or ignore specific
bits.
Software-Based Channel Level
Triggering. This mode differs from
the modes described previously
because the readings analog,
digital, or counter are interrogated
by the PC in order to detect the
trigger event. Triggering can also be
programmed to occur when one of
the counters reaches, exceeds, or
is within a programmed window.
Any of the built-in counter/totalizer
channels can be programmed as a
trigger source. Triggers can be
detected on scanned digital input
channel patterns as well.
Normally, software-based triggering
results in long latencies, from the
time a trigger condition is detected
until the actual capturing of data
commences. However, the
OMB-DAQBOARD-3000 Series
circumvents this undesirable
situation by use of pre-trigger data.
Specifically, when software-based
triggering is employed, and the PC
detects that a trigger condition has
occurred (which may be thousands
of readings later than the actual
occurrence of the signal), the
DaqBoard driver automatically looks
to the location in memory where the
actual trigger-causing measurement
occurred. The acquired data that is
presented to the user actually
begins at the point where the
trigger-causing measurement
occurs. The maximum latency in
this mode is equal to one scan period.
Stop Trigger. Any of the software
trigger modes described previously,
including scan count, can also be
used to stop an acquisition. Thus an
acquisition can be programmed to
begin on one event, such as a
voltage level, and stop on another
event, such as a digital pattern.

included software and without the
use of external hardware or

traceability through an on-board
reference that has a stability of
0.005% per year. The second
mode, user-cal, is for users who
require traceability to international
standards such as NIST. A 61⁄2 digital
multimeter is required and
user-calibration software is included
with step-by-step instructions for full
calibration. A 2-year calibration
period is recommended for the
OMB-DAQBOARD-3000 Series.
Analog Output
(OMB-DAQBOARD-3000 and
OMB-DAQBOARD-3001 only)
Two or four 16-bit, 1-MHz analog
output channels are built into the
OMB-DAQBOARD-3000 Series with
an output range of -10 V to 10 V.
Through the use of bus mastering
DMA, each D/A output can
continuously output a waveform at
up to 1 MHz, which can be read
from PC RAM or a file on the hard
disk. In addition, a program can
asynchronously output a value to
any of the D/As for non-waveform
applications, assuming 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 their 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 sources described below.
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.
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-DAQBOARD-3000 Series.
Digital I/O can be programmed in
8-bit groups as either inputs or
outputs and 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 the first mode, the
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. For example,
if 8 analog inputs are enabled with 0
delay period, then the digital inputs
in this mode would be scanned at
once per 8 µs, which is 125 kHz.
In the other synchronous mode, the
enabled digital inputs are scanned
synchronously with every analog
input channel. So in the example
above, the digital inputs would be
scanned at once per µs, or 1 MHz.
If no analog inputs are being
scanned, the digital inputs can be
scanned at up to 12 Msamples/s.

Digital Outputs and Pattern
Generation
Digital outputs can be updated
asynchronously at any time before,
during, or after an acquisition. Two
of the 8-bit ports can also be used
to generate a 16-bit digital pattern at
up to 12 MHz. The
OMB-DAQBOARD-3000 Series
supports digital pattern generation
via bus mastering DMA. In the same
manner as analog output, the digital
pattern can be read from PC RAM
or from a file on the hard disk.
Digital pattern generation is clocked
in the same four modes as previously
described for analog output.
The ultra low-latency digital output
mode allows a digital output to be
updated based on the level of an
analog, digital, or counter input. In
this mode, the user associates a
digital output bit with a specific input
and specifies the level of the input
where the digital output changes
state.
D1-6
The response time in this mode
depends on the number of input
channels being scanned and can
typically be in the range of
2 to 20 µs.
Counter Inputs
Four 32-bit counters are built into
the OMB-DAQBOARD-3000 Series.
Each of the four counters 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 multiaxis 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-DAQBOARD-3000 Series,
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 an external
clock source.
The OMB-DAQBOARD-3000
supports quadrature encoders with

Each input can be debounced from
500 ns to 25.5 ms (total of 16 selections)
to eliminate extraneous noise or
switch-induced transients. Encoder

in the same PC. The serial number
on each OMB-DAQBOARD-3000 is
used to differentiate one from
another, and a user-selected name
can be assigned to each board for
easy program documentation. When
multiple boards are installed, all
boards can be operated
synchronously by designating one
board as the master. All of the other
boards are then slaves, and are
synchronized to the master via the
pacer clock, which is externally
routed to the designated slave
boards.

Analog, digital, and frequency inputs
can be scanned synchronously,
based on either an internal
programmable timer or an external
clock source. Analog and digital
outputs can be synchronized to
either of these clocks.
Scan Clock Sources: 2
The maximum scan clock rate is the
inverse of the minimum scan period.
The minimum scan period is equal
to 1 µs times the number of analog
channels. If a scan contains only
digital channels, then the minimum
scan period is 83 ns times the
number of digital channels.

ANALOG OUTPUTS
(OMB-DAQBOARD-3000 and
OMB-DAQBOARD-3001 only)
Analog output channels are updated
synchronously relative to scanned
inputs and clocked from either an
internal on-board clock or an
external clock source. Analog
outputs can also be updated
asynchronously, independent of any
other scanning in the system. Bus
mastering DMA provides CPU and
system-independent data transfers,
ensuring accurate outputs that are
irrespective of other system
activities. Streaming from disk or
memory is supported, allowing
continuous, nearly infinite length,
waveform outputs (limited only by
available PC system resources).
