TOSHIBA Infrared Test Apparatus Team member: Ahmad Nazri Fadzal (EE), Nurfazlina Kamarudin (EE), Zamir Izam (EE), Wan Rahmatul Wan Othman (EE) Sponsor: Matthew Eshlemen, John Gawel, David Starling Problem to be solved Definition of need Database Mode Database Mode Panel This project designed a piece of automated test equipment that will receive IR signals from the H93 television set, compare them against a known good pattern, and graphically display the results for each control signal tested Toshiba’s goal is to achieve100% test coverage on all products. For the new H93 integrated TV, Toshiba does not test the remote control of third party DVDs and VCRs. This capability is called “IR Blaster”. Sampling Storage Analyzing Save Name file Library Graphical display Pulse width Start and stop trigger Edit signal feature Test Mode Toshiba H93 Digital Integrated TV Test Mode Panel Load signal Retrieve Signal Test output signal The H93 television outputs infrared signals using a device called “IR blaster” With the IR blaster, external devices, such as DVD and VCR players can be connected to the TV and can be controlled using the H93 remote control DVD/ VCR Select signal from library Start and stop trigger Edit signal feature Compare Result-pass/fail IR Blaster Graphical Display H93 TV Statistic Pulse width First error location Normal plot Expected & Actual signal plot on same plot Remote Control Conclusions This capability can be successfully used to test device for the IR Blaster The test program ensures that the signal that is transmitted from the TV to external devices has the correct characteristics, and that the TV performs the right task for every signal received Test Model Approach NI PCI 6533 Binary Data Signal Create a test program using LabView 7.1 Data Acquisition Device TV Connector Block Database Mode The output signals from the television are sampled and analyzed, and their characteristics stored in a library Test Mode Allows the user to capture the signal from the H93 TV under test, and compare it with a signal from a library created in the Database mode.
