Patent ID: 8255177

Claim:
A system for calibrating oscillograph channels, the oscillograph in communication with a signal generator, the system comprising: a storage system; and at least one processor to execute one or more programs stored in the storage system, the one or more programs comprising: a setting module operable to initialize channels selected by a user, and assign the same value to a drawing parameter of each of the initialized channels; a receiving module operable to direct each initialized channel to receive a signal from the signal generator and measure a signal voltage of the signal, and display a waveform chart of the signal voltage according to the drawing parameter; a calculation module operable to determine an initialized channel as a standard channel, calculate a voltage difference between a standard signal voltage of the standard channel and a signal voltage of each of the other initialized channels, and determine a sequence relationship between each of the other initialized channels and the standard channel measuring the signal at the same time according to the calculated voltage difference; and an execution module operable to adjust a deskew value of each of the other initialized channels according to the sequence relationship until each voltage difference is in an allowable range, and output the deskew value of each of the other initialized channels.
