What is the purpose of the SMPTE test pattern?

Explanation:
The SMPTE test pattern is a standardized reference image used to calibrate and verify the performance of video equipment. It provides grayscale steps, color bars, and alignment targets that let technicians adjust exposure, gamma, black and white levels, color accuracy, and geometric fidelity. By using this pattern, a display or camera can be set up so that the image reproduces consistently and remains within specification over time, which is the essence of setup and quality assurance. The other options describe ultrasound concepts (transducer sensitivity, penetration, axial resolution) that aren’t what this video pattern measures.
