　　Introduction to SineImage Integrated Test Card

　　SineImage integrated test card YE05 is designed for TV camera general (visual) evaluation and design. This test card is mainly used for the evaluation of electronic camera transmission characteristics of the design. The circular graph is used to perform a rough linear evaluation of the scan. The gratings distributed at the image 2-MHz-line position can be offset by linearity in the horizontal and vertical directions. The distance between the gratings should be as equal as possible.

　　With the help of a line selection switch oscilloscope, a vertical wedge grid can be used to establish a modulation depth frequency response. The signal of the tilted 1-MHz block is used as a reference value. The wedge-shaped grid can further make a visual evaluation of the resolution limit. In addition, the crosstalk, notch filtering and comb filtering effects can be observed.

　　The triangular diagonal of the gray wedge is checked by linear staggering. The ladder of the line receives twisted pair.

　　The density is divided into four grades from D = 0.15 to D = 1.65 (contrast 32: 1) The density of the test card is D = 0.15. The density of the surrounding area is D ~ 0.75.
