Page 5: General Information
Delays up to 10 seconds may be programmed with 100ps resolution (1ps optional) and a channel to channel jitter of less than 50 ps RMS. BNC outputs deliver delayed pulses with adjustable level (3 to 6V) and width into 50Ω load. A polarity control allows to have inverted pulses. -
Page 6: Principle - Block Diagram
September 2015 1.2. Principle – Block diagram The principle of the MODEL 745-20C programmable delay generator is described in the figure bellow. The sequence follows 3 phases: 1) After an insertion delay, a reference pulse appear at the “T0” output, 2) Following the reference, a pulse is generated on each channel after the specified delay, 3) At the end of the sequence, after last delayed pulse outputs, the delay generators are initiate. -
