Tegam joins PXI Systems Alliance
Tegam has announced its membership in the PXI Systems Alliance (PXISA). Tegam specializes in waveform generators, precision amplifiers, RF power calibration, and low-level measurements.
Tegam is currently preparing to launch the Model 4040A Fast PXI Instrumentation Amplifier, which is designed to work with PXI digitizers and oscilloscopes. The Model 4040A offers 100-V differential inputs with 70 dB of CMRR. The bandwidth ranges from DC to 50 MHz with programmable gain, attenuation, offset, and filters. www.tegam.com.
Geotest unveils chassis and controller
The GX7600 mainframe from Geotest—Marvin Test Systems is a compact nine-slot PXI Express Smart chassis that accommodates up to eight instruments as well as an embedded single-slot PXI Express controller, such as the new GX7940, or a PXI Express remote bus controller, like the x1 or x4 MXI-PXI Express interface. The GX7600 also incorporates built-in hard-disk and DVD-RW drives, a 400-W power supply, and chassis smart functions, providing onboard per-slot temperature and power-supply monitoring.
You can team the chassis with the GX7940 PCI Express single-slot controller. The GX7940 comes with a 1.4-GHz or 2.0-GHz Pentium M processor and up to 2 Gbytes of memory. The module supports Gigabit Ethernet and USB interfaces, as well as the GX7600’s embedded storage peripherals. www.geotestinc.com.
Module streamlines distributed application development
An add-on module for National Instruments’ LabWindows/CVI 8.1 ANSI C development environment lets you create and deploy reliable and deterministic applications to dedicated real-time hardware, such as PXI-based systems and desktop PCs.
The LabWindows/CVI 8.1 Real-Time Module simplifies the process of transferring data between real-time and Windows applications, while its new high-resolution timing engine achieves more precise timing and determinism.
The network variable technology introduced in LabWindows/CVI 8.1 provides a simplified interface for communicating with applications written in LabWindows/CVI, LabView, Visual Basic .NET, and C#. Using network variables and the LabWindows/CVI Real-Time Module, you can publish and share live measurement data between test systems located on the factory floor and remote supervisory machines without the complexity of low-level TCP programming. www.ni.com.
Goepel introduces PXI JTAG controllers
Goepel electronic has introduced its SFX/PXI 1149/CX-x 1-slot/3U PXI boundary-scan controllers. Members of the company’s ScanFlex family, two-TAP and four-TAP versions are available in 20-, 50-, and 80-MHz performance classes. Exchangeable Conpac connector paddle cards simplify the interfacing with interconnection hardware from firms including Mac Panel and Virginia Panel. www.goepel.com.
