Introduction
Agilent U2781A USB modular
instrument chassis is a 4 U-high
chassis with six USB module slots.
This portable chassis provides
housing for up to six Agilent U2300A
Series USB modular multifunction data-
acquisition (DAQ) devices. This further
expands Agilent’s range in PC-based
data-acquisition solution, especially in
the research and development (R&D),
design-validation, and manufactur-
ing fi elds, where engineers use DAQ
extensively.
The U2781A modular chassis is an AC
powered device and is equipped with
an external 10 MHz reference clock and
external trigger-in and trigger-out
functions.
Easy to Use
The USB 2.0 high-speed interface gives
the device plug-and-play and hot-swap-
ping connectivity.
High-Density Data Acquisition
The U2781A modular chassis allows an
expansion of up to 384 channels when
slotted with the U2300A Series DAQ
devices, providing a high- density data
acquisition solution.
Triggering Using Star Trigger
Bus
The U2781A USB modular instrument
chassis comes with star trigger bus,
which offers precise synchronization
between USB modules and the external
trigger signal. The star trigger bus pro-
vides dedicated trigger lines between
the external trigger input and slotted
USB modules.
Users can also achieve precise
triggering between each USB module
via the synchronized routing of the star
trigger.
System Option
The U2781A modular instrument
chassis has an optional mountable
rackmount kit. This allows a better
setup when it is integrated into a test
system.
Compatible with wide range of
ADEs
The Agilent U2300A DAQ devices are
compatible with a wide range of
Application Development Environments
(ADE). This minimizes all the time taken
by R&D and manufacturing engineers
to use the devices in different software
environments as they can program
directly using SCPI commands.
Listed below are the popular
development environments and tools
that the DAQ device is compatible with:
• Agilent VEE and Agilent T&M Toolkit
• Microsoft Visual Studio.NET, C/C++
and Visual Basic 6
• LabVIEW
• MATLAB® (Agilent U2300A Adaptor
