This type of tests have the purpose that electrical and electronic equipment have a good performance, even with the possibility of being affected by being in an electromagnetic environment with signals that exceed the tolerable voltage that the equipment can end up with. The driven immunity comes from the ability of the equipment to work under a disturbed electromagnetic environment.
This test checks equipment operation by applying repetitive electrical transient bursts over AC, DC, and signal and telecommunication power lines. Electrical transients and/or bursts are generated by switching maneuvers in the interruption of inductive loads and contact bounce in relays, motors, compressors, etc. Other types of equipment that unintentionally produce RF electromagnetic radiation energy include inductive load switches, arc welding equipment, fluorescent lights, etc.
This test applies an amplitude-modulated signal (1 kHz – 80%) to the equipment, in the 80 MHz – 2.7 GHz frequency range. RF electromagnetic radiation energy fields are intentionally produced by TV stations, AM/FM radio stations, telephone base stations, citizens band radio equipment, mobile phones, etc. Other types of equipment that unintentionally produce RF electromagnetic radiation energy include inductive load switches, arc welding equipment, fluorescent lights, etc.
Since the Industry 4.0 concept was introduced into the market, factories and manufacturing processes have experienced different transformations to make them smarter, by linking various up to now isolated disciplines, from design to production, automated inspections, embedded sensors to give an authoritative overview of product status and testing. Any space customer is aware of it and about the unquestionable benefits that will bring for new space missions.
At Alter Technology, our laboratory capabilities allow us to provide services on customer equipment (CPE) from the early stages of definition (requirements, applicability environment, test plans), integration into ISP Network systems, contact and support with manufacturers, to field deployment tests at the end customer's home (FUT).
Development of new approaches to the electrical test: On line test, embeded test lab, ..., etc. There is a tendency, and a need, to test electronic components and systems remotely, trying to determine their behavior and characteristics in a wide range of situations. This task includes the ability to monitor certain variables and their possible variation: current, temperature, ..., etc., to be able to execute parametric and functional test tests in line on digital, analog and mixed signal circuits. These methodologies have a great value in order to perform environmental and reliability tests, even considering the use of new test platforms such as in-flight tests with cubesat, ..., etc.
Design of printed circuits and integration of test systems. It is easy to understand that the high performance offered by new electronic devices demand test environments with even superior features that allow measurements without introducing "artifacts" that may affect the results. This process is becoming a challenge, especially when we take the technology to limits of frequency, speed, volume of data, etc.
Development and validation of test environments dedicated to non-standard EEE Parts The world of electronic devices is a very extensive discipline, covering a wide range of products with very different characteristics and testing needs. Some of them require dedicated test approaches that are specific to the function, technology and failure modes of each device. For example, the harmful effect that certain current impulses can generate on tantalum capacitors is known, which makes it necessary to design a test environment that allows analyzing this effect.
Physical Analysis and Materials It is well known the negative effect that radiation can induce on electronic components and systems. There is a wide variety of effects that depend on the radiation environment (type of radiation: gamma, protons, cosmic rays ...) and the type of technology and devices used. In this section we work to develop better tools to perform radiation tests, we will perform tests to understand and characterize the radiation phenomena on different technologies, exploring simulation tools and developing mitigation techniques to improve the radiation tolerance of different instruments electronic.

During the visit of the students in the facilities located in La Cartuja, they did not only have the opportunity to visit the facilities and laboratories, but they were also introduced to the company and were shown an example of the type of activities we carried out , using the SAOCOM satellite as reference.
Through the Cátedra program, Alter Technology has supported the University of Seville to present itself to organize one of the most important events of Education for Space applications.. “Host organization of the 3rd Symposium on Space Educational Activities” during the year 2019. We are still waiting for the resolution, here you can see the information of the 2nd Symposium, which was organized by Budapest University of Technology and Economics (BME) in April 2018.
