A waveform generator embodied in a single tester unit. The hardware includes an integrated high frequency digital/analog signal generator that allows "infinite" length of signals, integrated colored noise source with thermal asperity generator and a PC style computer including standard storage systems and connectors that are custom configurable. Optionally, additional hardware such as an oscilloscope can be integrated to further centralize all the tools required by the engineer without adding interconnectivity problems for the engineer to deal with. The software includes a generic or standard operating system, GUI (graphical user interface), and specialized interface software for easy input/definition of sequences, waveform, and drive configuration. The software also includes a mathematical model of the head/disk system used in drives, with customization options, and the ability to do monte-carlo analysis to study distributions of signal waveforms.
