Introduction to SineImage Comprehensive Test Card

The SineImage comprehensive test card YE05 is specifically designed for general (visual) evaluation of television cameras.

The density is divided into four levels, with the standard increasing from D=0.15 to D=1.65 (contrast ratio of 32:1). The density of this test card is at the D=0.15 level. The density of the surrounding area is D to 0.75.

This test card is mainly designed for evaluating the transmission characteristics of electronic cameras. Circular shapes are used for rough evaluation of scanning linearity. The grating distributed at the 2-MHz line position in the image can shift linearity supervision in both horizontal and vertical directions. The distance between gratings should be as equal as possible.

With the help of a line selection switch oscilloscope, the application of a vertical wedge-shaped grid can establish modulation depth frequency response. The signal of the tilted 1-MHz block is used as a reference value. Wedge grids can further provide visual evaluations of resolution limits. In addition, cross color interference, notch filtering, and comb filtering effects can be observed.

Use linear interlocking on the three diagonals of the gray wedge block square for inspection. The stepped receiver in this row represents twisted pair cables.
