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 ...
The width of the vertical edge (which displays the jitter) of the displayed portion of the waveform, measured along a horizontal axis, should not exceed the oscilloscope’s specified jitter limits (e.g., for 20,000:1 specification, the oscilloscope’s contribution to the width should be less...
Techniques and procedures for calibration must measure these parameters, while coping with the functional conditions which surround them. Good metrological practice must be used to ensure that an oscilloscope’s performance at the time of use is comparable with that observed and measured during calibrati...
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...
Figure 7:You can pair NI oscilloscopes with the NI LabVIEW Jitter Analysis Toolkit to perform signal integrity measurements within NI LabVIEW. Back to top What is the Difference Between an Oscilloscope and a Digitizer? If you require more customizability than an oscilloscope, such as in-line FPGA...
One of the reasons for using a high-resolution oscilloscope is to measure small signals. 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...
When building a test system, one may need to measure more signals than a single oscilloscope can capture with its available channels. A common approach to increase the number of oscilloscope channels available in a test system is to combine multiple oscilloscopes. Applications fo...
Read our guide (with video) on how to choose the best oscilloscope (also called an "oscope") for your unique needs, including bandwidth, rise time, sample rate, channel density and triggering
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
4.3 Adaptable dummy Loop at start of critical interrupt This option is suitable when a user needs a simple solution for an application process sensitive to latencies that must be executed at equidistant intervals with no (low) jitter. The implementation of this...
