本文介绍一种能使1km左右的SIVP-75-18电缆对阶跃脉冲的响应时间补偿到≤lns的补偿原理。其新颖之处在于:在电缆补偿要求超过6dB/倍频程的频率范围内,必须设置多于一个极零对,并且多设置的极零对要单独分出来组成网络。用这种新补偿原理,已使840m SIVP-75-18加20m SYV-75-9电缆传输系统对阶跃脉冲的响应时间补偿到0.91ns,总衰减40dB。此外,我们研究了用Ti-59或Ti-58C可编程序计算器设计电缆补偿器的方法。
This article describes a compensation method that enables the SIVP-75-18 cable around 1km to compensate for the step pulse response time to ≤ lns. The novelty is that more than one pole-zero pair must be set in a frequency range where cable compensation requires more than 6dB / octave, and multiple pole-zero pairs must be separated to form a network. With this new compensation principle, the 840 m SIVP-75-18 plus 20 m SYV-75-9 cable transmission system is compensated for the step pulse response time to 0.91 ns with a total attenuation of 40 dB. In addition, we studied the design of cable compensators using the Ti-59 or Ti-58C programmable calculators.
