The D200 is a compact, DC-coupled fast laser driver, providing up to 4 amps of regulated constant current. A built-in edge-triggered pulse generator produces up to 1 microsecond pulse widths and 2 nanosecond transition times, capable of driving lasers with forward voltages up to 9 volts. A pulse-follower mode is also provided, accommodating externally-defined trigger widths up to 100% duty continuous-wave (CW). Power, pulse width, drive current and differential triggering functions are accessible through a ribbon cable header for embedded OEM applications. A low-inductance laser drive interface permits direct laser connection or custom interposer and flex-cable attachment.

The D200 is compatible with Highland's model P400 4-channel benchtop digital delay and pulse generator and model T560 4-channel compact digital delay and pulse generator.
