Autotestcon: Geotest highlights PXI modules and chassis
-- Test & Measurement World, 9/21/2007 1:37:00 AM
Geotest-Marvin Test Systems at Autotestcon debuted a standards module, differential digitizer, a PXI Express instrument, 3U and 6U chassis, a signal generator, a digital I/O instrument, and controllers:
• The GX1034 is a new standards module in its line of analog PXI instrumentation products. The GX1034 offers PXI system designers the capability to develop a system recertification strategy that employs only internal system resources. By incorporating the GX1034 as part of a system configuration, it is possible to develop a system-accuracy verification strategy that can recertify a system’s source and measure base-band instrumentation. The module features NIST traceable voltage, resistance, and frequency standards. “The GX1034…offers test system designers and users a better method for recertifying and calibrating PXI-based systems and modules,” said Mike Dewey, senior product marketing manager at Geotest. “By incorporating this module as part of an overall system certification strategy, support and maintenance logistics for ATE systems will be much improved, resulting in better system availability and reliability.”
• GX2472 is a dual differential channel, 70 Msample/s, 14-bit digitizer in Geotest’s line of PXI analog instrumentation. “Like many of our other PXI products, the GX2472’s differential inputs, coupled with its 14-bit, high-speed converters makes this instrument unique in the PXI marketplace,” said Dewey. “We expect to see the GX2472 being used in a variety of high-performance applications that require the acquisition and analysis of high-fidelity or low-level signals.” The module’s differential inputs, coupled with its low distortion, makes it suitable for analyzing high performance or low level analog signals, Dewey said.
• The GX5292e is an addition to Geotest’s family of 3U PXI Express products. The GX5292e supports both x1 and x4 PXI Express interfaces. Based on the GX5292, the GX5292e supports deep pattern memory and offers 256 Mbytes of on-board vector memory with dynamic per-pin direction control and with test rates up to 100 MHz. The single-board design supports both master and slave functionality without the use of add-on modules. According to David Manor, Geotest VP of engineering, many of Geotest’s digital instruments feature deep vector memory, and “PXI Express really complements these designs. The faster data transfer rates associated with PXI Express will result in significantly faster vector load and unload times, which means faster test execution times for applications.”
• The GX7002A-MP and GX7302-MP products are additions to the company’s family of 3U and 6U chassis. The two new chassis incorporate MAC Panel SCOUT receivers, which offer a method for connecting test-system resources to a mass interconnect receiver, minimizing the need for cable assemblies. “The MAC Panel solution offers a superior method to interface test system resources to the ITA and helps to eliminate the need for cumbersome wiring harnesses and their inherent reliability issues,” said Loofie Gutterman, Geotest president. “A PCB assembly is more cost effective, easier to maintain, and above all, very reliable. And the SCOUT receiver is modular, which means you can select from a variety of connectors to suit your requirements.” The GX73x2-MP incorporates a 20-slot 3U PXI chassis that can accommodate up to 19 instruments as well as an embedded PXI controller or a PXI bus expander interface such as the GX7990 or MXI-4. The
GX70x2A-MP incorporates a 20-slot 6U PXI chassis that can accommodate up to 19 instruments as well as a PXI controller or a PXI bus expander interface such as the GX7990 or MXI-4. Like all of Geotest's chassis, the GX7302-MP and GX7002A-MP incorporate “Smart” features, which support the monitoring of slot temperatures and system power-supply voltages as well provide the ability to program or map each PXI trigger line from one PCI segment to another.
• The GX1110 is a single-channel PXI signal generator that offers both arbitrary waveform and DDS-based function generator capabilities within one instrument. Said Manor, "With both the function-generator and AWG modes of operation, users have the flexibility to address a broad range of applications, including signal-distortion simulation and base-band audio test. When combined with our new waveform creation software WaveEasy, users have a very capable and useful set of tools for creating and generating arbitrary and periodic waveforms for a variety of applications.” The GX1110 features 2 Msamples of memory, supports a 100-MHz sample rate, and is capable of generating low-distortion sine waves up to 30 MHz.
• The GX5055 high-performance dynamic digital I/O instrument is an addition to Geotest’s line of
6U PXI digital products. With an I/O voltage range of -10 V to +15 V with a full 25-V swing; per-pin programmable drive, sense, and load capabilities as well as deskew per pin; and a 50-MHz vector rate, the GX5055 supports test of complex digital products including LRU and SRU assemblies. “The GX5055 represents a new level of performance and capabilities for PXI-based digital instrumentation that was previously only available in VXI,” said Gutterman. “Designed to address a broad range of mil/aero digital test applications at both the factory and depot level, we expect a high level of interest from users looking to create next-generation digital test platforms based on PXI’s high performance and compact footprint attributes.”
• The GX7922, GX7924, GX7932, and GX7934 are additions to the company’s line of 3U
and 6U PXI controllers. With technology based on the Intel Core Duo processor, these controllers offer increased performance over previous generation processors with no increase in power consumption. When installed in a Geotest 3U or 6U chassis, the controllers provide an integrated, high performance, single slot, PXI controller that supports all integrated chassis peripherals (hard drive, DVD, etc.) and provides a variety of I/O interfaces, including USB, Gigabit Ethernet, and RS-232. The 6U controllers provide a front panel accessible PMC slot, which can accommodate a variety of interfaces and functions for specific applications or needs.
