Triggered Data Recording with DIAdem DAC


In certain cases, a "selective" data measuring is desired in order to save memory resources. This funcionality is provided by this DAC diagram.

  • A function generator produces a sine.
  • We only want to record data when the value > 1.
  • If the window with undesired values [-10 ... 1] is entered, a trigger stops the data saving and hides the F1 car.
  • The Not operator inverts this trigger, starts the data saving and shows the F1 car.
