摘　　要：为了能够在工业现场进行SDI传输特性的测量,开发了一种基于FPGA的3GSDI信号传输测试装置,可以生成标准的彩条信号或者接入测试图像源,通过FPGA内串行化或解串行输入输出通道的SDI信号进行传输误码率的统计及延迟的测量,并通过内部计算得到测试结果。In order to measure the transmission characteristics of SDI in industrial field,a kind of 3G-SDI signal transmission test device based on FPGA is developed.It can generate standard color bar signals or access the test image source,and measure the transmission error rate and delay by serialization or de-serialization of SDI signals in the input and output channels of the FPGA.The test results are obtained by the internal calculation.
