设计者在UCF文件中通过SYSTEM_JITTER关键字指定的系统抖动参数是直接传递至XST静态时序分析工具的。 XST静态时序分析工具使用SYSTEM_JITTER约束时会根据被分析路径中同步元件的数量,按照“和方根”的方式对本路径的系统抖动进行合成,这一点在UG612中并无说明。 一个添加了200ps SYSTEM_JITTER约束的设计,查看布局/布线完成...
The system processes the second set of presentation time stamps of the transcoded video stream to determine if the second presentation time stamps include jitter, and based upon determining the second set of presentation time stamps include jitter modifying the second set of presentation time stamps ...
Linux kernel version 5.14 introduces theosnoise tracerthat also measures the system jitter / noise. It additionally shows you the sources of the jitter. Example Measure jitter on CPUs 0 through 3: $ taskset -c 0-3 hiccups | column -t -R 1,2,3,4,5,6 cpu threshold_ns hiccups pct99_...
Techniques for emulating operating system jitter on a platform using a given trace are provided. The techniques include calculating a scale factor, wherein the scale factor is equal to a maximum of measured overhead of introducing synthetic jitter on the platform and a resolution of one or more...
PCM9211: System clock jitter Akio Ito Genius3595points Part Number:PCM9211 Hi, Can we get 50-ps ultra-low jitter system clock even if below condition? A. The biphase signal has the biggest jitter in the tolerance of IEC60958-3.

A UDP jitter test cannot be started. Unless otherwise specified, the commands provided in "Procedure" are run in the NQA test instance view. Possible Causes Mandatory parameters of the NQA test instance are incorrectly configured. Procedure Check whether the type of the test instance type is...
Configuring a UDP Jitter Test Verifying the Configuration Example for Configuring an NQA TCP Test to Measure the Response Time on an IP Network Example for Configuring an NQA DNS Test to Measure the DNS Resolution Time on an IP Network Example for Configuring an NQA UDP Jitter Test to ...
To measure the eye diagram of a high bit rate optical signal, the authors have generated a sampling pulse by gain switching and have reduced the timing jitter by using CW light injection. The system jitter was 0.7 ps, and the signal-to-noise ratio was 20 dB at a signal peak power of ...
在选项卡上 监控 在对象 任务配置 您可以在运行时监控各个任务的周期性抖动值。周期性抖动与基于延迟的释放抖动不同。请参阅以下定义: 周期性抖动 周期性抖动(J经过) 是一个任务的周期时间的偏差 (T经过)从所需的任务循环时间(T0)。 Ĵ经过 = T经过 -T0 所需(理想)循环时间 T0 在任务的配置中使用 间隔...
