New Multifunction USB Data Acquisition Products from Measurement Computing
Norton, Massachusetts, Measurement Computing has announced the release of three new 1-MHz, 16-bit multifunction USB data acquisition devices, and a cost-saving expansion module for high channel count applications. The USB-1616HS, the USB-1616HS-2, and the USB-1616HS-4 deliver outstanding performance with synchronous analog, digital, and frequency I/O in one compact package. The AI-EXP48 plug-in expansion module coupled with any of the USB-1616HS series modules can quadruple the analog input channel count.
The USB-1616HS series modules have a unique, low-latency control output mode, whereby any input-analog, digital, or counter, can control an output-digital, analog, or timer, based on pre-defined limits, including hysteresis. The outputs are controlled directly from the USB-1616HS series module, and do not require PC intervention. This results in response times that are measured in microseconds instead of milliseconds.
The USB-1616HS series offers extensive trigger options, ranging from analog trigger with 1 µs max latency, to multichannel triggering, where any combination of analog, digital, and counter input channels can be combined to initiate the trigger. Other trigger modes include digital pattern, level, edge, inside/outside window, and pre- and post-trigger.
USB-1616HS series features:
Analog I/O
o 16 single-ended / 8 differential analog inputs o 16-bit resolution o 1-MHz throughput rate o 7 programmable input ranges from ±100 mV to ±10 V full scale o Any analog input can measure voltage or thermocouples-any TC type on any channel o Over-sampling mode, including line-cycle rejection for ultra stable TC and low-level voltage measurements, even in the presence of AC power line noise o Two 16-bit, 1-MHz analog outputs (USB-1616HS-2 only) o Four 16-bit, 1-MHz analog outputs (USB-1616HS-4 only)
Digital I/O
o 24 digital I/O bits
o 4 MHz throughput for digital I/O and counter input data o 4 counter inputs capable of measuring frequency, period, pulse width, or quadrature encoders up to 20 MHz o 2 timer outputs
Synchronous I/O-all analog inputs, analog outputs, digital I/O and counter/timer I/O can occur synchronously, resulting in precise time correlation among all I/O.
Low latency control outputs capable of responding to inputs in as fast as 2 µs.
The packaging for the USB-1616HS series is designed to make it easy for the user to use in a variety of applications. Removable screw terminals facilitate attaching and removing without having to re-wire. The modules can be easily DIN-rail mounted for applications where the device is mounted in a rack or with a protective enclosure.
The number of analog input channels on the USB-1616HS series can be quadrupled with the addition of the AI-EXP48 analog input expansion module option, increasing from 8 diff/16 single-ended inputs to 32 diff/64 single-ended inputs. All of the features of the built-in analog channels are included when the AI-EXP48 is attached, including the ability to measure thermocouples on any input channel. Users can simply plug the AI-EXP48 directly into a USB-1616HS series module, or use an optional cable.
The USB-1616HS series modules ship with an impressive array of software, including the new TracerDAQ®, a full-featured, out-of-the-box data logging, viewing, and analysis application; Universal Library(TM); UL for LabVIEW(TM); and InstaCal(TM) installation, calibration, and test utility-powerful software solutions for programmers and nonprogrammers alike.
