Data Acquisition System
OMB-DAQTEMP14A, shown smaller than
actual size, with screw terminal/signal

OMB-DAQTEMP14A hardware
consists of a plug-n-play PCI board,
a 0.9 m (3') cable, and a screw
terminal/signal conditioning pod.
Cold-junction compensation is
built in to the OMB-DAQTEMP14A,
allowing for highly accurate
thermocouple measurements,
with channel-to-channel variation
and noise typically less than
0.2°C, and absolute accuracy
typically better than 1.0°C. This
is accomplished by having a

conditioning solution for highaccuracy, high-speed temperature,
voltage, frequency, and pulse
counting measurements, plus digital
I/O and analog output.

including Visual Basic and C++.
D1-1
separate low-noise, bandwidthlimited amplifier per thermocouple
channel. The OMB-DAQTEMP14A
has 14 thermocouple input
channels. All power for the
OMB-DAQTEMP14A is derived
from the PC, so there is no need
for external power supplies
or transformers.
In addition to thermocouple inputs,
the OMB-DAQTEMP14A features
7 differential voltage input channels,
with 16-bit resolution and
programmable full scale input
ranges from ±156 mV to ±10 V.
The 4 frequency input channels can
measure frequency or count pulses
up to 10 MHz. Two timer output
channels can generate square
outputs up to 1 MHz.
Twenty-four digital I/O lines are also
included, which can be programmed
in 8-bit groups as either inputs or
outputs.
* In order to provide maximum temperature
stability, the thermocouple channels have
a 4 Hz filter.

screw terminal/signal
conditioning pod included.
The 16-bit/100 kHz analog
outputs can be used to
generate waveforms, with a
virtually infinite waveform
output length possible from
PC memory.
All inputs and outputs are
accessible via convenient
screw terminals located on
the signal conditioning pod. The
user can easily remove the cover of
the signal conditioning pod to gain
access to the screw terminals for
signal connections.
DAQVIEW SOFTWARE
The included DaqView software
allows the user to verify signal
connections, acquire and save data
to disk, and graphically view realtime data within moments of
installing the system. Easily set up
all hardware, acquisition, and
display parameters, without
programming, via a simple,
spreadsheet-style screen. DaqView
is a full-featured acquisition and
display application that provides all
the functionality needed for many
data logging applications.
OMB-DAQVIEW-XLPLUS
DaqViewXL is an optional Excel
add-in that provides complete data
acquisition functionality. Seamlessly
integrated into Excel’s tool palette,
DaqViewXL has the same
comprehensive acquisition and
display capabilities as DaqView.
Excel is an ideal tool for test
engineers because it provides a
variety of graph and charting
functions for presenting data in a
graphical format, as well as
mathematical and analysis functions
such as FFTs. Excel’s ability to
retrieve and manipulate previously
acquired data in a spreadsheet
format and DaqViewXL’s advanced
data acquisition functions form a
comprehensive data acquisition
solution.

thermocouple, then the driver
automatically compensates for the
delay required to obtain the reading,
resulting in a maximum latency of
one scan period.
