1. A method for presenting information on a digital oscilloscope, the method comprising:

  • making primary measurements of a signal;

    displaying data from the primary measurements as a function of time;

    deriving parameters from the data of the primary measurements; and

    displaying the derived parameters as a function of time with the data from the primary measurements, wherein the step of deriving the parameters comprises;

    identifying cycles in the signal;

    comparing the primary measurements in each cycle to a threshold; and

    determining peak-to-peak variation in amplitude of the cycles.
