Instrument connectivity and modularity were in focus at Autotestcon 2009, as vendors touted new LXI and PXI instruments. Von Campbell, LXI Consortium president, took to the stage with representatives of Agilent Technologies, The MathWorks, Pickering Interfaces, and VTI Instruments to update attendees on consortium news and to provide LXI system-implementation advice (see "LXI: setting up systems, working with IT"). On the exhibit floor, The MathWorks presented a demonstration of LXI-compliant instruments from Agilent and Tektronix running in conjunction with Matlab in a communications-test application.
ZTEC Instruments presented three new series of high-resolution 300-MHz-bandwidth oscilloscopes in PCI, PXI, VXI, and LXI form factors. Christopher Ziomek, ZTEC president, said the new ZT4420 (12-bit), ZT4430 (13-bit), and ZT4440 (14-bit) scopes are the fastest sampling oscilloscopes or digitizers available in PCI, PXI, VXI, and LXI at these levels of ADC resolution.
Geotest presented a flurry of PXI-related news, announcing that it has expanded its preconfigured GBATS (Geotest Basic Automated Test System) PXI systems to cover analog, digital, mixed-signal, and avionics test needs. The company also released its GX7944 embedded controller for PXI Express platforms; it’s based on the Intel Core 2 Duo, 2.16-GHz processor. Geotest also introduced a PXI instrument that offers 32 channels of digital I/O, with 32 Mbits of vector memory per channel. The new GX5291 card supports 1.5-V, 1.8-V, 2.5-V, 3.3-V, and 5-V TTL/LVTTL logic families and supports a maximum vector rate of 50 or 100 MHz. The company also said it has enhanced the features and vector load/unload performance for its current series of PXI dynamic digital I/O cards. Finally, Geotest introduced a new product, DtifEasy, that can import, convert, and execute IEEE 1445-compliant digital test vectors generated by a Teradyne LASAR simulation.
National Instruments announced it is offering PXI interface modules for MIL-STD-1553, ARINC 429, and AFDX military and aerospace avionics applications as a result of the company’s collaboration with AIM, a provider of avionics instrumentation. By configuring, distributing, and servicing PXI systems that feature AIM interfaces, NI can serve as a single point of purchase for military/aerospace customers who require avionics interfaces as part of their NI PXI-based systems. NI also announced the NI TestStand ATML Toolkit to help engineers reduce development and maintenance time by expanding test-system component interoperability and increasing test-system documentation. ATML (Automatic Test Markup Language) is an IEEE standard consisting of XML document formats that describe different aspects of a test system. The new toolkit adds support for the ATML TestDescription standard and improves support for the ATML TestResults standard in NI TestStand.
Aeroflex announced that the US Department of Defense awarded Aeroflex a five-year, $40.5 million contract with the US Marine Corps to supply GRMATS (Ground Radio Maintenance Automatic Test Systems). For this contract, Aeroflex will supply its newly developed test platform, the 7200 CATS (Configurable Automated Test Set), which incorporates PXI instruments.
In other news, JTAG Technologies highlighted its JFT (JTAG Functional Test) tool, which simplifies test preparation and interpretation of results for sequential clusters. It can help engineers test mixed-signal parts such as ADCs and DACs, and it supports the looping of test patterns to set up device registers. JFT includes a built-in Python open-source script editor and a code template. JFT operates as a plug-in module to JTAG’s ProVision tool.
Finally, start-up RT Logic demonstrated its T400CS Telemetrix 400-channel simulator, which addresses a range of IF and RF hardware-in-the-loop test applications. The instrument creates IF and RF signals that match those of transmitters and receivers in motion with respect to one another, reducing the need for actual aircraft, satellite, or missile flights during test and training operations.
