**如需客製化大小、比例，請聯絡客服**

測試卡說明

測試圖在白色背景上有水平23個和垂直53個直線柵格。 3個網格線從中間劃分外圍的3行網格。網格線的寬度是影像寬度的0.15%。大圓形線的直徑為83是影像高度的1/3%，5個小圓形線的直徑是影像高度的25%。

4分辨率鈸被分佈在大圓的0°、45°、90°和135°處，對應的2-10MHz訊號頻率（8 MHz和800線的標記結束）。

應用

·此測試圖專門為營運調整和控制TV攝影機而設計。

·圓圈的線性掃描可以檢粗濾的評估視覺。

·網格線的目的是調整定位。

·鍥的目的是鑑定解析度。

A grid structure consisting of 23 horizo​​​​ntal and 35 vertical lines is arranged on a white background. 3 grid lines each divide the outer 3 grid rows in the middle. The width of the grid lines is 0.15% the has the has the has the lular has is 0.15% the has the has the lular has the 0. 1/3% of the picture height, the 5 small circular lines have a diameter of 25% of the picture height. 

4 resolution wedges are arranged in the large circle at angles of 0°, 45°, 90°, and 135° corresponding to signal frequencies of 2-10 MHz. (The marking ends at 8 MHz and 800 lines). 

UTILIZATION

·The test chart is designed for operational adjustment and control of TV cameras.

·The circles permit rough visual appraisal of scan linearity.

·The grid lines serve the purpose of adjusting registration.

·The wedges serve the purpose of resolution appraisal.
