National Instruments CompactDAQ systems are less expensive than equivalent systems within the NI PXI Platform.
Hardware
CompactDAQ systems are managed by a chassis controller module, which controls data transfer between up-to 8 I/O modules and a
PC.

CRC Press, 19-Aug-2011 The following types of chassis controllers are available:
*USB Chassis - designed for small, portable, mixed-measurement systems on the benchtop or in the field
*Ethernet Chassis - ideal for distributed measurement systems in locations where

and support for over 50 measurement-specific modules
CompactDAQ systems connect to sensors via wired or wireless I/O modules, connected to a chassis controller.
Currently only NI C Series modules are compatible with the CompactDAQ platform.
Modules are available with
analog inputs and

LabVIEW integrates with CompactDAQ chassis controller hardware to connect to physical sensor or signal data sources. LabVIEW can also connect to oscilloscopes and USB DAQ systems using the ''Measurement and Automation eXplorer'' (MAX) LabVIEW component.
In LabVIEW, virtual instruments can be configured and simulated, in order to test data processing when physical hardware is not available.
The ''Virtual Instrument Software Architecture'' (VISA) is the back-end component that manages communication between LabVIEW and CompactDAQ hardware.
NI SignalExpress LE is provided with every chassis controller for basic data logging and analysis. NI SignalExpress is a
Microsoft Windows application that provides features for acquiring, analyzing, and displaying data from compatible data acquisition devices and instruments.
