Hi @GCL The instruments output trigger high while running. Selecting Wavegen as trigger output it will constantly output high after starter, if no trigger condition or wait time is set. Your approach with scope and patterns looks good, but in order output pulse with each trigger event select "scope detector" as trigger in patterns. In this case you don't have to have the scope running. You can create signal with constant, like 0 in idle and output high, with wait and run you can adjust
