1. A method of providing a waveform display characterizing a device under test comprising the steps of:

  • storing a data sequence from the device under test that represents the response of the device under test to an input signal;

    displaying a plurality of windows on a display screen, a first one of the windows displaying a first waveform representing the data sequence;

    displaying menu items in a second one of the windows, each menu item corresponding to one of multiple operations that may be performed on the data sequence to produce an output data sequence;

    selecting one of the menu items and a third one of the windows;

    performing the operation indicated by the selected menu item to produce from the data sequence the output data sequence;

    storing the output data sequence;

    displaying in the third window a second waveform representing the output data sequence;

    selecting another one of the menu items and a fourth one of the windows;

    performing the operation indicated by the another selected menu item to produce from the data sequence another output data sequence;

    storing the another output data sequence; and

    displaying in the fourth window a third waveform representing the another output data sequence.
