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.
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-USB-1408FS have two 12-bit analog
outputs.
The packaging for the OM-USB-1208FS, OM-USB-
1408FS 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.
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 PDF.
