The Pulsed laser diode Test system is a comprehensive synchronous test system for early testing of laser diode manufacturing processes, especially when appropriate temperature control cannot be easily achieved. The KEITHLEY 2520 provides all the source and measurement capabilities required for laser diode pulse testing and continuous LIV(opto-current-voltage) testing in a compact, semi-rack-mounted instrument. The close synchronization of the source and measurement ensures high measurement accuracy and enables testing to a minimum pulse width of 500ns.
