Production, Test, Calibration, Warranty and Maintenance Structure Build-to-Order All products at Spectrum are BTO (build to order). All Spectrum products consist of a base module (M4i-PCIe, M2i-PCI, MX-PXI, ...) and one or two analogue modules plus some optional modules like star-hub. Analogue modules may differ in speed grades and the number of soldered channels. We stock these modules and typically have several hundred modules on our shelf. If we get a request for delivery time or an order we first check whether we have all the necessary modules in stock. If yes, the production is placed in our BTO queue and the delivery time will be dependant on the other production requirements. The production process consists of the modules being assembled together, maybe some small soldering work (for any necessary changes) and then several hours of test, specification checking and calibration. The normal delivery time is one to two weeks. If there's an urgent delivery we can possibly put this at the beginning of the queue, depending on the promised delivery times of the other products already in production. In the case where we don't have all needed modules in stock the delivery time will depend on the time it takes to produce the missing modules. This time may vary. Delivery times are then typically around six weeks. However, this time can be reduced if we have vision of a pending order. Again, in urgent cases, we can sometimes rework modules with different speed grades to generate the required modules. This will depend on the type of modules available and their suitability to be reworked. In-house Testing After production of the instrument an intense and defined test of the product is done. The test has two purposes: • Check that all parts of the product are running and fully functional with all features of the card being tested against different limits. Check that the product reaches the stated quality as shown in the data sheet. Specifications are checked for each individual product that leaves our factory. Spectrum makes a lot of effort to improve the quality of the products during development time, maintenance and production.

Production, Test, Calibration, Warranty and Maintenance Structure • Detailed test and calibration protocol for card production. Results are documented for every product that is delivered. Use of a semi-automated test procedure which stores test results in an in-house test data base for further checks and quality improvements. Use of automatic test routines that check technical figures. Documentation of all hardware and software changes and all versions that are delivered to customers. These changes are available online at our website for the customer as a revision history. Detailed service cards...

Production, Test, Calibration, Warranty and Maintenance Structure Warranty + MTBF The standard warranty of all our products is an industry-leading five years from the date of delivery. In that time all hardware failures that are not due to misuse by the user are repaired free of charge by Spectrum. After the warranty period repairs are done based on a card check and quotation. Products are repaired as long as Spectrum is able to source all the needed parts. Based on our experience the service support time after the end-of-life of the product is in the region of 7 to 10 years. MTBF figures are...
