Abstract: A method, apparatus and computer program having instructions for storing information in an oscilloscope is provided. The method comprises the steps of storing a screen display in a predetermined format, storing one or more configuration settings associated with the screen display, and storing in memory channel acquisition data associated with the stored screen display. The screen display may also be annotated, the annotation information being stored as well. The stored screen display, one or more associated configuration settings, and stored channel acquisition data, and annotation data, if applicable, may be loaded into the oscilloscope, thereby placing the oscilloscope in the state it was in when the stored data was originally generated.

Abstract: A method and apparatus for determining a bit error rate. The method comprises the steps of acquiring a data signal by an acquisition unit of a test instrument for a predetermined period of time, and storing the data signal in a memory of the test instrument. A clock signal is recovered from the stored data signal, and in accordance therewith, the stored data signal is sliced into a plurality of data segments of a predetermined length. Each of said data segments is synchronized to a frame or predetermined pattern to determine a bit error rate thereof.

Abstract: A method and apparatus for capturing an analog waveform on a serial bus. The method comprises the steps of designating a predetermined digital data sequence, decoding a serial data signal carried on a serial data bus, and comparing the decoded serial data signal to the predetermined digital data sequence. When it is determined that a portion of the decoded serial data matches the predetermined digital data sequence, the portion of the serial data signal corresponding to the matching portion of the decoded serial data signal is marked.
