TE278用于测量和描述电子8K（UHD TV2）摄像机的频率响应。
测试图由50个多波场场组成，分布在16：9的图像区域。 这些场在水平和垂直方向上排列以测量两个方向上的分辨率。 所有字段都以分辨率（每个图像高度的周期）进行标记。 一个循环由一条黑线和一条白线组成。
中间的两行以不同的方式排列。上排考虑到，分辨率在图片的中间。因此，4000 cph场在中间，频率向两侧减小。
频率从左侧的200cph增加到右侧的4000cph。 该行可用于测量和描述被测相机的频率响应。
The TE278 is designed to measure and describe the frequency response of an electronic 8K (UHD TV2) camera.
The test chart consists of 50 multiburst fields, which are distributed over 16:9 picture area. The fields are arranged in horizontal and vertical direction to measure resolution in both directions. All fields are labeled with the resolution in cycles per picture height. A cycle consists of one black and one white line.
The two rows in the middle are arranged differently. The upper row takes into account, that the highest resolution is in the middle of the picture. Therefore the 4000 cph field is in the middle and frequencies decrease to both sides.
In the lover row the frequencies increase from the 200 cph on the left to the 4000 cph on the right. The row can be used to measure and describe the frequency response of the camera under test.
