HDTV Мега цикл тестовый Рисунок 16:9 Калибровочная плата YE0239 настраиваемая диаграмма Бесплатная доставка

TE239设计用于检查HDTV摄像机调制深度的频率响应和调制深度的均匀性。
测试图由19个多脉冲串组成，分布在16：9的图像区域。
这些区域在水平和垂直方向上排列以便测量这两个方向上的分辨率。所有区域都用数字指定，给出相应的频率（MHz）。频率根据1080/50i系统计算。
该行区域由从3到36MHz的频率组成，行中间具有27.5MHz。27.5MHz脉冲串的左边和右边，定位一个1MHz的模块。频率以3MHz的步幅增加。在图的四个角落是27.5MHz模块包围着1MHz的切口。这些缺口作为参考频率。

The TE239 is designed for checking the frequency response of modulation depth and the uniformity of modulation depth of HDTV cameras. 

The test chart consists of 19 multi burst 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 designated with figures, which give the corresponding frequency in MHz. The frequency is calculated in accordance to the 1080/50i system. 

The row consists of frequencies from 3 to 36MHz with the 27.5MHz field in the middle of the row. To the left and right of the 27.5MHz burst one 1MHz field is positioned. The frequencies increase with steps of 3MHz. In the four corners of the chart are 27.5MHz fields surrounded by bursts with 1MHz. These burst serve as reference frequency.
