VALID LINE Functional test platform

Choosing a functional test solution means that it must satisfy (at least) three fundamental requirements: - The solution should meet present and future performance needs - The solution should retain the ability to adequately mimic features of old, to-be-replaced equipment. - The solution should include comprehensive hardware and software tools and yet be fully open to COTS (Commercial Off-The-Shelf) hardware and software. The Valid Line is the ultimate integrated functional test solution, capable of meeting and exceeding these requirements for analog, digital and mixed-signal testing, both...

Valid line FACTORY AND DEPOT SRU/LRU FUNCTIONAL ATE VERSATILE TEST ARCHITECTURE At the heart of the system is the VIP test backplane. Controlled by the system PC through the high-speed fiberoptic bus, the VIP test backplane hosts channel cards, routing cards and internal instrumentation. The VIP test backplane offers unrivalled flexibility, with full connection to the test receiver, ample room for expansion, built-in signal and power buses to accommodate all requirements of stimuli and measurement distribution to the UUT (Unit Under Test). The Valid Line can be provided with a traditional...

POWERFUL TEST GENERATION, VALIDATION, RUN-TIME ENVIRONMENT As are all Seica systems, the Valid Line is based on the powerful VIVA software environment. CAD data can be directly imported to create a comprehensive data base for test generation, validation and diagnostics. The board schematic, layout and nomenclature are dynamically linked and controllable by the user. Test steps and source code are also synchronized during execution to ease debug. VIVA also includes a number of tools specifically oriented for functional test generation such as a simulator for digital test, a Virtual Channel...

Valid line LOW COST MODULAR, COST EFFECTIVE SYSTEM CONFIGURATION AND ERGONOMICS With the Valid Line you are not locked into a single system configuration. The base system is offered on a vertical architecture, combining a prestigious looking line with a high degree of ergonomics essential for operator comfort. The system includes an ample work/desk area and a flat, adjustable LCD monitor. The main diagnostic instruments (manual measurement probes, oscilloscopes, transducers) are strategically located above the test adapter section. The System bay can be supplied in the traditional Seica...

Designed around a common hardware and software architecture, the Valid Line is offered in several different configurations to address for the customer; ergonomics, test strategy, and deployment from board depot to full production level test. VALIDATE AND VALID PLUS BOARD TEST SYSTEMS FOR LEVEL III VALIDATE ValidATE is the architectural implementation of the Valid Line for Level III (Board Test) applications. The system bay measures 60x96x182 cm and hosts 28 card cage slots using a VIP Test Backplane for a capacity up to 768 digital (or 384 full hybrids) high performance functional channels....

Valid line LEVEL II: LOW COST MODULAR ARCHITECTURE Special to Type Test System (STTE) integrators have justified their choice based on cost advantages potentially offered by targeting the solution on the specific end product requirements, as opposed to the more general but more expensive General Purpose ATE (GPATE). In trying to accomodate the multiple requirements of hundreds of LRU that can be part of a final system, from serial to parallel digital, from LF to RF from , Optronics to Pneumatic, the cost of instrument, routing and interfacing often exceed budget limitations. Furthermore,...

REAL TIME TEST EMULATION When UUTs are part of complex systems, the ATE will be able to emulate the operating conditions by applying multiple stimuli and making multiple measurements in parallel. The iFUN is an analog test card designed to fulfil these requirements of realtime signal generation and measurement at functional test. The card includes 16 four quadrant, grounded DC voltage generators, programmable up to 20V with 16 bit resolution. The DC generators allow simultaneous application of independent signals at the inputs of the UUT, to precisely reproduce discrete signals coming, for...

Valid line LEGACY REPLACEMENT Seica can safely claim to have the most experience on Legacy Replacement of obsolete ATE, inclusive of the replacement solution, the tools for TPS migration and the service to provide turn-key solutions. From the old GR179X/GR2750,Computer Automation (CA) Marathon, and S79X test systems, to the more recent L3XX systems, Seica has successfully served customers worldwide to migrate thousands of test programs, assuring life extension to long term defense products. There are several reasons to make Seica the preferred partner, and the Valid Line the preferred...

OPEN SOFTWARE ENVIRONMENT All Seica instruments are fully supported by COM libraries to allow direct integration with external environments, such as Nl TestStand or Agilent VEE, and can be programmed by external languages or graphic tools. Similarly, the Seica test environment can call directly and execute software objects developed within external test engines like LabView, LabWindows CVI, etc. This architecture allows the user the advantages of years of experience embedded in Seica's products and the flexibility to take advantage of other commercial products as well. For example, allowing...

Valid line ROUTING ARCHITECTURE Routing signals from instrumentation to the UUT has always been the bottleneck for the test system. An easy solution is, of course, to bring all signals from instrumentation to the receiver, and then assure switching and connections on the fixture; but at what cost! Most ATE solutions have an internal signal bus, where instruments connect through instrument switching cards, as well as separate switching channel cards going to the UUT. To limit space required by the matrix relays, complex multiplexing solutions are often used. Instead, the Valid Line uses a...
