Product Description
The USB4CH is a 4 channel 24 bit realtime continuous data acquisition
system with an individual A/D per channel architecture.
Suitable for sampling from DC to 10kHz, an on board 2 MB
FIFO guards against any data loss even on heavily interrupted and
multitasking computers. Sitting outside the PC for improved noise
performance, the system communicates its acquired data to the computer
via a standard USB port. All analog inputs are fully differential
with amplitude ranges of +/- 4 volts.
Full featured acquisition and display programs are included with
the system software, so you can be
up and running immediately, easily controlling acquisition rates and
continuously saving acquired data to disk. For developing custom
applications, low level functions for controlling the system are supplied
as static and DLL libraries. Windows and Linux software is provided with
source code included.
The bundled "in the box" system comes with the accessories you
need to start acquiring data immediately. These include software, PDF
User manual, 9 VDC power supply, 6' USB cable, alligator analog input
cable, and a desktop enclosure. A PC104 adapter plate can be
substituted for the desktop enclosure at no additional charge.
