Function description

General

This function block is used to generate a pulse of defined duration (tPT) after a rising edge at the input xIN. The generation of the pulse can also be triggered independently by the simulation input xTest (rising edge). The time difference to the pulse start is displayed at the output tET (value range: 0 … tPT) .
