History of jitter Part 4: Time-interval error (TIE)David MaliniakTeledyne LeCroy
Assuming only random noise, you've quantified the time-interval error Jitter (TIE Jitter) in a signal as an RMS value. You want to determine, if a bit-error ratio (BER) bathtub plot were to be measured for this signal, what the plot's eye closure is at a
时钟信号抖动定义有多种主要是: 周期抖动(Period Jitter) 相邻周期抖动 (Cycle to Cycle Period Jitter) 长期抖动 (Long Term Jitter) 相位抖动 (Phase Jitter) 时间间隔误差 (Time Interval Error or TIE) 2.1 周期抖动 周期抖动是时钟信号的周期时间相对于一定数量、随机选定的理想时钟信号周期的偏差。如果我们能...
时钟抖动的原因就是噪声。相位抖动因为需要累积一段时间,所以这个误差又称为 时间间隔误差(TIE, Timer Interval Error)。 3.3 占空比(Duty Cycle Distortion) 占空比失真,即时钟不对称,有脉冲的时间和无脉冲的时间发生了变化。DCD 会吞噬大量的时序裕量,造成数字信号的失真,使过零区间偏离理想的位置。DCD通常是由...
Note that the measurement of the change in TE at each interval really becomes measurement of a short-term variation, or jitter, in the clock signals, or what is sometimes called timing jitter. And as TIE is a measurement of the change in phase, it becomes a perfect measurement for capturin...
1) time interval jitter 时间间隔抖动1. And its time interval jitter is 20 ps (peak to peak jitter) and 2 ps (RMS jitter). 利用该技术获得的高精度时钟和输入激光的时间间隔抖动为峰峰抖动小于20ps,RMS小于3ps,该精度指标国内未见相关报道。
In development and testing of high speed digital communications or optical storage systems it is a frequent requirement to measure jitter, frequency, time interval (skew), time interval error (TIE), pulse width, pulse coincidence etc. While modern oscilloscopes can be used for some of these ...

time-interval measurement [′tīm ‚in·tər·vəl ‚mezh·ər·mənt] (horology) A process that consists either in calculating the duration between two known epochs, or in counting the repetitions of a recurring phenomenon from an arbitrary starting point, as with an electronic di...
In all test instances except jitter and ICMP jitter test instances, the timeout period set by the timeout command must be smaller than the interval of automatic tests set by the interval command. Otherwise, the tests fail due to timeout of test packets. Precautions If you attempt to change...
