6 Series B mixed signal oscilloscope displaying jitter
Understanding How To Analyze Jitter Wednesday, November 17, 2021
Steve Sandler, President of Picotest, as well as Maria Agoston, Cameron Lowe, Tony Ambrose, all of Tektronix, also contributed to this blog. Why You Should Care About Jitter Jitter is a common problem. A quantified misplacement in time of the signal relative to the expected time position, jitter is ultimately a degradation of the key definition of performance of a serial link, which is the bit …

How Do the Latest PCIe Generations Compare to IEEE 802.3ck Electrical Ethernet? Tuesday, November 9, 2021
One of the featured sessions during the 2021 Tektronix Innovation Forum was one entitled PCIe Gen5, Gen6 Development and Contrast to IEEE 802.3ck Electrical Ethernet, featuring myself and my colleague, Pavel Zivny. At that session we began by discussing the current status for PCI Express 5.0 at 32 GBd NRZ.  Next, we looked ahead to the transition to PCI Express 6.0 at 32 GBd PAM4, reviewing key …

Beamformer Frontends and Up-Down Converter ICs for mmWave 5G Infrastructure Wednesday, October 27, 2021
Why Beamforming Lies at The Heart of 5G & 6G Radio Design Momentum behind 5G continues to grow, with the vast spectrum available at 5G millimeter wave (mmWave) frequency bands supporting extreme capacity, high throughput and low latency and an increasing number of 5G mmWave devices, from smartphones to laptops and more. The testing and characterizing demands of new 5G networks, however, are …

Measuring the Control Loop Response of a Power Supply with an Oscilloscope Tuesday, October 5, 2021
Power supplies and voltage regulators are typically designed to maintain a constant voltage over a particular current range. The supply should respond quickly to demand changes while maintaining a constant output, without excessive ringing or oscillation. To do this, power supplies are essentially amplifiers with a closed feedback loop. Control loop measurements help to measure how a power supply …
Access and control your oscilloscopes remotely with TekScope PC analysis software
Using TekScope Software to Enhance the Capabilities of Your Bench Oscilloscope Friday, August 20, 2021
Most bench oscilloscopes have many built-in features that allow you to do a lot of analysis and operations on the instrument itself. But sometimes, there is a need to do some offline analysis.  So, this article talks about why offline analysis is necessary and how to use offline analysis software.  Why offline analysis is worth considering Here are some reasons why you might sometimes want to (or …
Oscilloscope cloud software integration with TekDrive
New TekDrive Python SDK Allows for Seamless Integration into Your Workflow Thursday, August 19, 2021
Getting data off your oscilloscope and into the hands of a colleague or a processing program can be a hassle — and that is exactly the problem that TekDrive solves. TekDrive allows effortless collaboration by transferring, storing, organizing, managing and sharing data and files. And now doing all of that is even easier thanks to the new Python SDK! The TekDrive API allows you to perform multiple …

A 3-Step Process to Identify Electromagnetic Interference (EMI) Monday, July 26, 2021
Radiated emissions, most often referred to as electromagnetic interference (EMI), are carefully regulated to ensure reliable operation and safety for users of electrical and electronic equipment. Regulations limit the allowable radiated emissions, and to keep their products within these limits, designers invest significant time and effort. One reason why EMI poses challenges is that emissions are …
Four-Wire Resistivity Measurements Monday, May 17, 2021
This article is based on a presentation by Mary Anne Tupta, Senior Applications Engineer, Keithley Instruments, a Tektronix company, at the American Physical Society March 2021 Meeting.   Measuring resistivity accurately is crucial in research on devices and materials like superconductors, conductors, low power materials, semiconductors, and intrinsic semiconductors. Essentially, a sample’s …

How to choose the best oscilloscope Tuesday, May 11, 2021
Oscilloscope bandwidth System bandwidth determines an oscilloscope’s ability to measure a signal. Specifically it determines the maximum frequency that the instrument can accurately measure. Bandwidth is also a key determining factor in price. Determine what you need – use the ‘five times rule’ For example, a 100 MHz oscilloscope is usually guaranteed to have less than 30% attenuation at 100 MHz …

What is an oscilloscope? Tuesday, May 11, 2021
An oscilloscope, formerly known as an oscillograph, is an instrument that graphically displays electrical signals and shows how those signals change over time. It measures these signals by connecting with a sensor, which is a device that creates an electrical signal in response to physical stimuli like sound, light and heat. For instance, a microphone is a sensor that converts sound into an …
