Measurement Computing Corporation rolled out the USB-501-TC-LCD thermocouple data logger with an LCD display. The logger supports K-, J-, and T-type thermocouple. It supports a wide range of temperatures and is ideal for harsh environments. With the USB-501-TC-LCD thermocouple data logger, users can take a quick look at the numbers on location without downloading to the PC first. The USB-501-TC-LCD battery-powered remote logger sells for $100.
The Ashling Opella-XDS560 is a high-performance JTAG debug probe that supports all Texas Instruments (TI) platforms. The Opella-XDS560 works with TI’s Code Composer Studio (CCStudio) integrated development environment (IDE). It seamlessly plugs into the CCStudio environment enabling convenient debugging of application code that is actually running on the target system. Opella-XDS560 supports CCStudio version 3.3 and version 4 and is available for $1,495 (US). Opella-XDS560 is also available as a bundled solution with the OMAP3 EVM for $2,499 (US).
ADLINK Technology launched the PCI-98×6 series of PCI digitizers. The PCI-9816, PCI-9826 and PCI-9846 4-channel, 16-bit high-resolution digitizers offer sampling rates of 10 MS/s, 20 MS/s, and 40 MS/s respectively. ADLINK also offers customized input ranges or higher bandwidth options on the PCI-98×6 series for OEM applications. The PCI-98×6 series of digitizers is currently available for a list price starting at $1,699.
Signatec announced the EC14150 wideband signal acquisition card for commercial laptop computers. The compact, low-power form-factor offers 150 MHz sampling rate on two channels, 14-bit resolution and 512 MB onboard RAM, yet consumes only 4.5 W, ideal for mobile data acquisition applications. The Signatec EC1450 is a 54mm-compliant ExpressCard board equipped with standard Plug and Play features common in PCI systems. The entire 512 MB memory may be used as an exceptionally large FIFO for acquiring data directly to the ExpressCard bus continuously (Continuous Record Mode) or in Data Transfer Mode, block acquisitions to RAM and transfers to PC modes.
Strategic Test introduced the UF3-3242 and UF3-3240 12-bit digitizer cards for the PCI bus. The UF3-3242 has 2 analog inputs and can sample at 500 MS/s on one channel or 250 MS/s on both channels simultaneously. The UF3-3240 is a single-channel card that samples at up to 500 MS/s. Both cards are supplied with 128 MSamples (256 MByte) onboard memory. The memory can be expanded to 2 GSamples giving a measurement time of up to 5 seconds on one channel at 500 MS/s. The single-channel UF3-3242 card is priced at $7895 and the two-channel UF3-3240 is $8695, with volume/OEM discounts available. PCI Express versions of the cards will be released later this year.
GAO Embedded introduced the XDS510PP JTAG Scan Path TI DSP Emulator Pod. The XDS510PP is an emulator used for debugging hardware and software and for flash programming. The XDS510PP DSP emulator is compatible with Texas Instrument’s XDS510, +3.3V or +5V processors, SPI110 Opto Pod, and 4 channel ITAG expanders. It operates via a parallel port on a PC or laptop and supports bi-directional EPC and EPP transfer. The XDS510PP can operate under Windows 98ME/2000/XP/NT.
Data Translation introduced the DT9816-S multifunction, high throughput, simultaneous USB data acquisition module. The DT9816-S enables engineers to sample six analog input channels independently at up to 800 kHz per channel. The DT9816-S includes software that helps users get up and running quickly. Users can develop their own software in a variety of languages, or use one of our ready-to-measure applications, including Measure Foundry, a powerful drag and drop test and measurement application. The DT9816-S is priced at $595 and is shipping 4 weeks ARO.

A test case in applications development is a set of conditions or variables under which a tester will determine whether an application or software system is working correctly or not. When testing user interfaces, it is easy to overlook test cases that would be helpful for a more thoroughly tested solution. The following list identifies twenty test cases that should be considered when testing user interfaces.
Measurement Computing launched the USB-7202 and USB-7204 data acquisition boards. The USB-7202 and USB-7204 boards feature a new O/S-independent protocol that enables DAQ devices to be programmed with simple text-based messages. The USB-7202 and USB-7204 boards combine small form-factor, bus-powered USB hardware, and a light and agile software framework that can be ported to multiple operating systems. The software framework is called Message-Based DAQ (MBD). The MBD protocol simplifies driver and application development because all DAQ operations are programmed through a common command interface, which is composed of a consistent, extensible firmware interface and an open-source, cross-platform API.
