8-Channel Voltage Input USB Data Acquisition Modules

These modules operate under
Microsoft Windows 2000/XP/Vista
(32-bit or 64-bit)/7 (32-bit or 64-bit)
operating systems.

The OM-USB-1208FS, OM-USB
1408FS and OM-USB-1608FS data
acquisition modules are supplied
with TracerDAQ software which is a
collection of four virtual instrument
applications used to graphically
display and store input data and
generate output signals:

• Strip Chart—Log and graph

values acquire from analog
inputs, digital inputs,
temperature inputs and
counter inputs

• Oscilloscope—Display values

acquired from analog inputs

• Function Generator—Generate

waveforms for analog outputs

• Rate Generator—Generate

waveforms for counter outputs

TracerDAQ PRO is an enhanced
version of TracerDAQ.

A comparison
of some of the features included in
TracerDAQ vs TracerDAQ PRO is
shown on the next page.

The OM-USB-1208FS,
OM-USB-1408FS and
OM-USB-1608FS are USB 2.0 full­speed voltage input data acquisition
modules (fully compatible with both
USB 1.1 and USB 2.0 ports). These
are plug-and-play modules which
draw power from the USB cable–no
external power supply is required. All
configurable options (including
individual channel ranges) are
software programmable, and the
modules are fully software calibrated.

The OM-USB-1208FS and
OM-USB-1408FS feature eight
analog voltage input channels that
are processed through a single
A/D converter. The analog inputs to
the OM-USB-1208FS are software
configurable for either eight 11-bit
single-ended or four 12-bit
differential inputs. The analog inputs
to the OM-USB-1408FS are
software configurable for either eight
13-bit single-ended or four
14-bit differential inputs.

The OM-USB-1608FS offers true
simultaneous sampling of up to eight
16-bit single-ended analog voltage
input channels which is
accomplished through the use
of an individual A/D converter
per channel. Models USB-1208FS
and USB-1408FS have 8
independent digital I/O channels and
model OM-USB-1608FS has
16 digital I/O.

Supply Required

All modules have one 32-bit counter
channel. The digital I/O channels
are software programmable for
input or output. Additionally, models
OM-USB-1208FS and OM-USB­1408FS have two 12-bit analog
outputs.

The packaging for the
OM-USB-1208FS, OM-USB­1408FS and OM-USB-1608FS
ensures ease of use in a variety
of applications.

The OM-USB-1208FS,
OM-USB-1408FS and
OM-USB-1608FS modules
ship with an impressive array of
software, including the new
TracerDAQ

®

, a full-featured,
out-of-the-box data logging, viewing,
and analysis application; Universal
Library™; ULx for LabVIEW
(comprehensive library of VIs and
example programs compatible with
LabVIEW v8.2.1 and later) and
InstaCal™ installation, calibration,
and test utility—powerful software
solutions for programmers and
nonprogrammers alike.
