现代多路通信设备的生产和维护都迫切需要测量的自动化.传输特性测量主要是电平测量,包括绝对电平和电平差、增益和衰耗、扣除基准点的偏差、失配衰耗和不平衡衰耗、失真衰耗等. 自动测量系统简介早期的自动测量系统,大多数是纸带直接控制的电平测量系统.到1974年,西门子公司研制成功计算
Modern multichannel communication equipment is urgently needed for the production and maintenance of measurement automation.Transmission characteristics measurement is mainly the level measurement, including absolute level and level difference, gain and attenuation, deduct the deviation of the benchmark, the mismatch attenuation and not Balance loss, loss of distortion, etc. Introduction to Automatic Measurement System Early automatic measurement system, most of the tape directly control the level measurement system to 1974, Siemens developed a successful calculation
