精确分辨率测试卡简介

　　精确分辨率测试卡TE199设计用于分辨率精确测量。该分辨率测试卡由6行，每行10个矩形脉冲串组成。 这些场以0.1MHz的步长分级，并且以这种方式排列，具有最高分辨率的行位于图表的中间。 在第一和第二行之间放置0.1和0.2MHz的低频脉冲串，在第3和第4行之间有0.7,0.8,0.9,1.0MHz的低频脉冲串，在第5和第6行之间有0.3,0.4,0.5和0.6MHz的脉冲串。

　　低频场的排列如下：

　　Introduction to Accurate Resolution Test Cards

　　Accurate resolution test card TE199 is designed for accurate resolution measurement. The resolution test card consists of 6 lines, each consisting of 10 rectangular bursts. These fields are graded in steps of 0.1 MHz, and in this way, the lines with the highest resolution are located in the middle of the graph. A low frequency burst of 0.1 and 0.2 MHz is placed between the first and second rows, and a low frequency burst of 0.7, 0.8, 0.9, and 1.0 MHz is between the third and fourth rows, and at the fifth and sixth lines There are 0.3, 0.4, 0.5 and 0.6 MHz bursts.

　　The low frequency field is arranged as follows:
