ACCES Unveils USB-AO-ARB1 Arbitrary Waveform Generator to Relieve CPU from Complex Task

By CIOReview | Friday, February 6, 2015

SAN DIEGO, CA: ACCES I/O Products – a provider of analog, digital, serial communication and isolated I/O boards and solutions – announces the availability of its USB-AO-ARB1, an USB high speed waveform output board to perform multiple embedded applications besides reducing the burden of complex tasks on CPU.

USB-AO-ARB1 Waveform Output Board

The arbitrary waveform is user-defined digital values that are clocked through Digital-to-Analog (DAC) for converting to analog output signal or waveform generation. ACCES’s new module handles waveform timing at hardware level to unload tasks from CPU applying First-in, First-out (FIFO) and control logic. These high quality waveforms, compatible with various operating systems including Windows and Linux, are used for self-test functionality, flexible stimulation or simulation of scientific or industrial test equipment. This maximizes the full functionality of hardware by broadening the ability of high speed USB.

Design and Functionality

The new small-sized waveform output board comprises a steel powder-coated enclosure with an anti-skid bottom and provides support for any semiconductor application in all kinds of industrial environment. The DIN rail mounting provision is available to install. The board comprises installment flexibility inside most enclosures or systems with its Original Equipment Manufacturer (OEM) USB/104 form factor that can connect to PC/104 form factor with its unique printed circuit board (PCB) and mounting holes.

The USB-AO-ARB1 has the liberty to be added at the top or the bottom of any PC/104, PCI-104 or PCI/104-Express stack through USB port that includes on-board with embedded CPU form factors. The module is 1000-times faster than USB human interface device (HID) driver by utilizing high-speed customized function driver that is optimized for carrying maximum data to output.

The module also includes sample programs including Visual Basic, Delphi and Visual C++ for Windows and installation files and basic sample program through open source kernel driver for Linux.

Additional Features

The USB-AO-ARB1 also offers multiple features, such as:

- 16-bit analog output for timed waveforms up to 8MHz with USB 2.0 and 3.0 device compatibility

- Start/stop control for hardware through second Bayonet Neill–Concelman (BNC) connector or software command.

- Three unipolar and bipolar output ranges

- 10000 Ohm pull-up/pull-down resistors on Digital Input/Output (DIO) lines with selectable jumper

- 8 digital lines buffered with 32mA sink/32mA source current and can be configurable as inputs or outputs in group of 4.

- Alternate micro-fit embedded USB header connector

- USB connector of Type B category with industrial strength and high-retention design

- Operational temperature is between -40 to +85 degree Celsius and voltage 3.3V
