Knowing the quality of the scope’s measurement system is paramount when you need to have accurate measurement results. While banner specs like bandwidth, sample rate, and memory depth provide a basis of comparison, these specifications alone don’t adequately describe oscilloscope measurement quality. Figure 1: Keysight Infiniium S-Series… (Show moreShow less)
Eye diagrams are extremely helpful in testing the physical layer fidelity of clock or serial data, but many engineers don’t know: What they are Why they should use one How to easily set one up They actually aren’t that complex when broken down. Eye diagrams can quickly give you insight into your signal, along with any jitter or anomalies… (Show moreShow less)
IEEE Standards for 400G optical Ethernet links have been in development for many months, and the specifications are finally stabilizing as of mid-2017. The result will be the first optical standards to employ PAM4 modulation. This requires a new set of measurements, with the TDECQ (Transmitter and Dispersion Eye Closure Quaternary) measurement… (Show moreShow less)
By now, you’ve probably heard about Keysight’s new 1000 X-Series oscilloscopes. We talked about them a lot during Scope Month, and you might’ve seen some of the blogger reviews from Hackaday, ElectroBOOM, and EEVblog. The 1000 X-Series features ultra-low cost oscilloscopes from 50 to 100 MHz bandwidths. They have a starting price of $449 (USD)… (Show moreShow less)
Written by Min-Jie Chong The Need for New SAS-4 Storage Standard The increase of data traffic due to the advent of internet of things has driven the need for faster backbone and storage transmission to meet this need. The Serial Attached SCSI - 4 (SAS-4) is a new enterprise storage standard that is being created to meet this need. It supports… (Show moreShow less)
Understanding the effects of crosstalk in high speed communication circuitry and pin pointing the root causes have been extremely hard for designers, until now. Keysight’s industry leading N8833A and N8833B software not only identifies the crosstalk but also allows the user to determine the sources. In addition, it can remove the effects of the… (Show moreShow less)
Written by Sheri Detomasi There are many similarities and differences between oscilloscopes and wideband digitizers. How do you know which is the right tool for your measurement need? Oscilloscopes use wideband data converters and typically provide a broad range of functionality. They provide probing and visualization of time variant… (Show moreShow less)
Keysight just announced our new Infiniium S-Series oscilloscope promotion, it’s called “Your Scope. Your Way.” The S-Series oscilloscope (500 MHz to 8 GHz) has unmatched measurement accuracy with the best signal integrity and the most comprehensive measurement software for signal analysis, compliance, and protocol analysis. And now the… (Show moreShow less)
Written by Ailee Grumbine and Brad Doerr The design-to-manufacturing (D2M) process typically involves sequential stages from design to manufacturing. Each stage requires data collection that is specified in an initial design of experiments (DOE) and aimed at providing confidence that the design can meet critical requirements. Effective data… (Show moreShow less)
Keysight oscilloscopes are loaded with various applications. So many, that there may be some you don’t know how to use or don’t even know they exist. In the new Scopes University video series, Erin East and Melissa Spencer dive into when and how to use some of the different capabilities of the InfiniiVision and Infiniium oscilloscopes. Gain… (Show moreShow less)
