TE224频率响应测试卡爱莎测试图
TE224用于测量和描述电子HDTV摄像机的频率响应。测试图由50个多波模块组成,分布在16:9的图像区域内。 这些模块以水平和垂直方式排列可以测量这两个方向上的分辨率。所有模块都是用数字制定的,以图片高度为周期给出分辨率。一个有黑白相间的TV线循环组成。中间的两行以不同的方式排列。上面一排最高分辨率在图片中间。因此,中间为1000cph,频率向两侧降低。下面一行,频率从左侧的50cph增加到右侧的1000cph。该行可用于测量和描述检测的摄像机的频率响应。The TE224 is designed to measure and describe the frequency response of an electronic HDTV 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 designated with figures, which give the resolution in cycles per picture height. A cycle consists of on black an white TV 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 1000 cph field is in the middle and frequencies decrease to both sides.In the lover row the frequencies increase from the 50cph on the left to the 1000 cph on the right. The row can be used to measure and describe the frequency response of the camera checked.1、厂家货源正品官方直售,公司生产周期短,出厂严格检测,货品品质保障,可通过国家计量院计量。2、关于尺码机身和包装尺寸为手动测量,由于测量工具和测量方法不同的因素,会存在1cm误差,但是不用影响运输和使用。3、关于颜色本店产品都是实拍图片,但是由于不同显示器分辨不同以及色温和对比度差异有所不同。4、关于客服可以通过阿里旺旺随时联系我们,如果旺旺回复不及时,也可以拨打我们的热线电话 陈工:13310057372(技术与销售一体,直达客户需求)5、关于售后我们将提供完整的售后服务,包括15天退货,正品保证,交期保障等等。6、关于发货本店根据货物及客户需求,尽可能选择快捷方便的物流运输服务,一般情况发顺丰快递!
