Amplitude-wavelength (AW) space is a well-established technique for depicting the operational performance of surface texture measuring instruments. This paper describes the introduction of a third parameter to AW space: the in-plane scanning speed. We present a discussion of the equations derived from operational constraints and parameter interdependencies for a scanning stylus instrument: the NPL Areal Instrument. Constraints derive from instrument range, resolution, range of measurement force, probe tip geometry and the synchronisation of data acquisition. The equations combine to form a polygon in amplitude-wavelength-scanning speed space that defines the operating region of the instrument.
