Calibration Versus Metrology
There is no consistent demarcation between calibration and metrology. Generally, the basic process below would be metrology-centered if it involved new or unfamiliar equipment and processes. For example, a calibration laboratory owned by a successful maker of microphones would have to be proficient in electronic distortion and sound pressure measurement. For them, the calibration of a new frequency spectrum analyzer is a routine matter with extensive precedent. On the other hand, a similar laboratory supporting a coaxial cable manufacturer may not be as familiar with this specific calibration subject. A transplanted calibration process that worked well to support the microphone application may or may not be the best answer or even adequate for the coaxial cable application. A prior understanding of the measurement requirements of coaxial cable manufacturing would make the calibration process below more successful.
