Welcome to the Adept Scientific Press Room

Adept Scientific (Letchworth, Herts) extends its range of USB-based data acquisition devices from Measurement Computing Corporation (Norton, Massachusetts).

The USB-1602HS-XX family targets applications requiring sensitive, high-accuracy, fast-voltage measurement with reliable repeatability and high throughput, and is ideal for measuring analogue voltage at high speed.

The USB-1602HS-XX is a multifunction high-speed measurement and control board supported under popular Microsoft® Windows® operating systems. It features either two or four single-ended 16-bit analogue inputs with one ADC per channel or a maximum sampling rate of 2 MHz per channel. The input range is software programmable for ±10 V, ±2.5 V, or ±500 mV. It also has two synchronous 16-bit ±10 V analogue outputs, which can generate waveforms at up to 1MHz per channel; 16 synchronous digital inputs and 16 synchronous digital outputs; four 16-bit or 32-bit counters (which can be configured to be gated); two timer/pulse width modulation (PWM) generators and; three 16-bit or 32-bit quadrature detectors to measure linear and rotary position.

A 68-pin SCSI connector provides connections for all inputs and outputs. Four BNC connectors provide alternate connections for the two analogue inputs, external pacer clock and external digital trigger input.

The USB-1602HS-XX samples both analogue inputs, digital inputs and counter inputs simultaneously. It can synchronise AI, AO and DIO operations at rates of up to 1 MS/s, with aggregate throughput up to 8 MS/s.

Operations can be paced with an internal or external clock.

A 500 V isolation barrier protects your computer from ground spikes, and ensures a reliable data stream. The USB 2.0 high-speed driver transfers data at rates up to 480 Mbps. The device is powered by a 9 VDC, 1 A external power supply that is included with shipment. Factory and self-calibration tables are stored onboard in EEPROM.

As with all Measurement Computing data acquisition products the new devices are supported by the Universal LibraryTM, programming libraries and drivers for most popular Windows-based programming languages.  This complete function library saves the user time by simplifying the configuration and operation of the measurement board and reducing human errors by eliminating detailed, low-level functions.  The Universal Library requires little disk storage, making it ideal for integration into multiple instrument systems and OEM products.

In addition to the Universal Library, all the new USB DAQ modules listed below ship with an impressive array of software, including TracerDAQ®, a full-featured, data logging, viewing and analysis application; Universal Library for LabVIEW™, VIs and program examples for LabVIEW; InstaCal installation, calibration and test utility; and support for DASYLab®, icon-based data acquisition, graphics, control, and analysis software, and Measurement Studio MCC Edition, Visual Studio 2005/2003 components and controls optimised for test, measurement, analysis, and presentation — powerful software solutions for programmers and non-programmers alike.
