    Abstract : As electronics are getting both smaller and more advanced, the need to verify and validate remains and the means are getting more complex the more functions and components are added. Traditionally, in-circuit tests (ICTs) are performed by probing dedicated test points on the Printed Circuit Board Assembly (PCBA) in a test sequence that is unique to each product. READ MORE

  5. 4. Methods to simulate resistance at high resolution and accuracy

    University essay from Uppsala universitet/Elektricitetslära

    Keywords : variable resistance; digital potentiometer; potentiometer; simulate; resistance; variabel resistans; digital potentiometer; potentiometer; simulera; resistans;

    Abstract : In this paper, four methods to simulate or generate electric resistance at high resolution have been developed, tested and evaluated. Each method is called a Resistor Simulator and are numbered from one to four. READ MORE

  6. 5. Analog Front End Development for the Large Hadron Collider Interlock Beam Position Monitor Upgrade

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Oskar Björkqvist; [2019]
    Keywords : ;

    Abstract : The interlock Beam Position Monitor (BPM) system in the Large Hadron Collider(LHC) is responsible for monitoring the particle beam position at the point of thebeam dump kicker magnets and is part of the machine protection system. Thecurrent interlock BPM system has some limitations and because of this, an upgradeproject has been initiated. READ MORE
