TE277用于測量和描述電子4K（UHD TV）攝像機的頻率響應。

測試圖由50個多波場場組成，分布在16：9的圖像區域。 這些模塊在水平和垂直方向上排列以測量兩個方向上的分辨率。所有字段都以分辨率（每個圖像高度的周期）進行標記。一個循環由一條黑線和一條白線組成。

中間的兩行以不同的方式排列。上排考慮到，分辨率在圖片的中間。因此，2000 cph場在中間，頻率向兩側減小。

頻率從左側的100cph增加到右側的2000cph。 該行可用于測量和描述被測相機的頻率響應。

The TE277 is designed to measure and describe the frequency response of an electronic 4K (UHD TV) 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 2000 cph field is in the middle and frequencies decrease to both sides.

In the lover row the frequencies increase from the 100 cph on the left to the 2000 cph on the right. The row can be used to measure and describe the frequency response of the camera under test.
