Time [ns]
The driver converts a TTL trigger signal into a proportional
voltage of adjustable levels and with short rise times.
Typically, the rise time of a TTL signal of 20 ns or more is
converted into a slope with a rise time of 1 ns or 3 ns,
respectively.
Combined with an integrated-optical amplitude modulator, the driver allows operation in two different modes: a
switching mode for fast switching of a light source between
„On“ state and „Off“ state, and a pulse mode for generation of a short light pulse via one switching operation.
Benefits
• Extremly short switching times
• 1 ns and 3 ns rise time, respectively
