Timing, delaying, gating, pulsing and syncing functions. There are many practical modes of operation and features in addition to the traditional digital delay and pulse generator modes.
Four independent delay channels or Two fully-defined pulse channels s. Front-panel BNC outputs deliver TTL, ECL, NIM or variable level (-3 to +4 V) pulses into 50 Ω or high impedance loads.
The delay and pulsewidth for each channel are independent with 2-20 volt output range, allowing the user to drive a wide range of load circuitry. This pulse generator offers several operating modes, including continuous, burst, single shot and external trigger/gate, allowing complete control of the pulse outputs. - https://www.quantumcomposers.com/
