How to Measure Jitter 00:05:04 | 21 JUN 2018 This video reviews Low Voltage Differential Signaling or LVDS technology, eye diagram configurations, jitter measurement, and the tradeoff between different cable lengths and data rates. Resources arrow-right LVDS Training Series arrow-right DS90LV047...
Total Jitter Components A good technique to measure TJ uses a high-end digital sampling oscilloscope. This oscilloscopes need to have a better noise floor than the device under test, otherwise the performance of the device under test would be degraded and worsen by the noise of the oscilloscope...
All serial data streams and clocks have jitter (the difference between the arrival of an edge and the expected time of arrival). The jitter you see on an oscilloscope is a function of the signal's timing jitter and amplitude noise, plus the jitter and noise that the oscilloscope adds to ...
一、简介 用于测量抖动的最常用仪器之一是实时数字示波器(范围)。实时示波器必须正确配置才能进行准确的抖动测量。本应用笔记提供了设置示波器以获得最佳抖动测量精度的一般指南。 数字示波器使用内部时基定期对其输入进行采样。高端设备的采样率范围为 1 Gsps(每秒千兆样本)到 256 Gsps。图 1 说明了示波器如何采样和显示提...
Hi, I am trying to measure the frequency stability of an optical chopper over time using the Digilent Discovery 2. When using the Scope tool, I can see the square pulse train generated by the chopper, and the Frequency measurement gives me the frequency
The NMS monitors port traffic around the clock and determines the traffic trend on the network based on traffic curves of devices. The traffic curves seem to be smooth on the NMS although microbursts (packet loss) have occurred. The NMS obtains device data in SNMP get mode, which has th...

Actually this is what I want to measure using the evaluation board, and based on the measurement I want to decide whether I should use CYUSB generated clock to sample the ADC or I have to make another indepedent clean clock for the ADC. For the latter option, I do face the ...
The question is sometimes asked, why not just use a lower resolution instrument and a smaller range to “zoom in” on the signal to measure small voltages? However, many signals have both a small signal and a large signal component. Using a large range, you could measure the large signal...
