The ILX Lightwave LDP-3840/01 is a precision pulsed current source engineered for laser diode characterization and dynamic device testing. It delivers peak pulse currents to 1 A with selectable output polarity, pulse widths from 100 ns to 10 µs, and rise times below 40 ns. Built-in laser protection—including output shorting, transient suppression, AC power-up sequencing, and redundant safety circuits—safeguards sensitive devices throughout operation and power cycles.
