Overview The LDP-3840B precision pulsed current source is a microprocessor-based instrument specifically designed for pulse testing and characterizing laser diodes. The LDP-3840B provides up to 3A of peak pulse current with adjustable pulse widths from 100ns to 10ms. Precision pulsed current to 3 A. Clean current pulses with fast rise times (. At the heart of the LDP-3840B is a precision pulsed current source that delivers clean pulses with low overshoot and fast rise and fall times. The 3840B’s low noise, transient-suppressed output is designed specifically for laser diode load levels.

Digital control of pulse width, duty cycle and frequency provide quick and easy control of pulse parameters for maximum flexibility in varying test applications. For accurate monitoring of laser drive parameters in LIV applications, laser diode mounting boards are available with 50 ohm terminated connections for voltage and current monitoring. The intuitive front panel of the LDP-3840B is designed for quick and easy instrument operation permitting precise pulse control. Pulse modes and parameters are logically grouped together without confusing multifunction keys allowing easy adjustment of pulse width, duty cycle and frequency.

A selection of instrument operating modes includes pulse polarity, constant duty cycle and constant pulse repetition interval (PRI). In constant duty cycle mode, the set duty cycle is maintained while adjusting pulse widths. In constant PRI mode, the set pulse interval is maintained while adjusting pulse width. The bright 4-digit LED display is easy to view in laboratory environments. Precision digital tuning is easy with the front panel adjustment knob.
