Additional compliance testing costs, external lab testing, debug engineering time, and in some cases, board spins can add significant costs and time delays to your project. Unfortunately, for companies new to EMI/EMC, estimating compliance testing cost can be somewhat challenging. In this blog, we’ll provide information on …
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 …
In 75 years of innovation, one thing still unites every aspect of technology from a cell phone to a space shuttle. Batteries.
At the forefront of testing those power supplies we all depend on has been the team of engineers at Keithley Instruments, a Tektronix company based in Solon, Ohio. Just outside of Cleveland, Keithley has had an outsized impact on the world of technology dating back to 1946 …
In mission-critical industries such as aerospace, healthcare, automotive, and others where human lives are at stake, properly calibrated electronic test and measurement equipment can be the difference between life or death. For many organizations that have in-house calibration labs, stakeholders rely on the calibration lab to be a source of truth when it comes to accurate calibrations and safety …
The vintageTEK Museum on Tektronix’s Beaverton, Ore., campus holds thousands of pieces of the 75-year-old company’s historic equipment, dating back to 1946. Since 2011, it’s where engineering and electronics enthusiasts of all ages have gone for hands-on tours, and where engineers volunteer to restore pieces for future display. The museum also provides education about Tek oscilloscopes, frequency …
The consumer computing industry demands a new form of IO's that can deliver on a vision of future needs. These needs include improved video and audio quality, such as 2K, 4K, and 8K displays, shrinking of the system form factor so that we can design thinner, lightweight laptops, and flexible performance. Thunderbolt technology™️ meets the competing demands of a convenient standards-based …
For metrologists, test lab managers, and calibration coordinators in aerospace and defense manufacturing, satisfying AS9100 calibration requirements can be an intense exercise requiring precise scheduling for whole labs of test and measurement equipment – all with the goal of keeping any downtime to a minimum.
Keeping and maintaining calibrations for AS9100 audits is essential but can be time …
Tektronix founder’s family reflects on their family’s company 75 years on
Before Tektronix was a several thousand-employee, global technology innovator, it was a small post-World War II operation on Portland’s eastside run by Howard Vollum.
Today the company’s spacious Beaverton campus still bears his name and a half dozen or more Oregon university awards and science labs have …
In industries such as aerospace, automotive, healthcare, aviation, and others where human lives are at stake, properly calibrated electronic test and measurement equipment is paramount. It can literally mean the difference between life or death, success or failure, profit or loss.
When a company performs a calibration on their lab equipment, they receive a calibration certificate as evidence of …
Controlling instruments remotely has become a part of nearly every engineer’s and researcher’s life, whether by working remotely or combining instruments into large test systems. The Keithley 4200A-SCS Parameter Analyzer supports a few different methods of remote control optimized for each scenario. This blog introduces remote control using Microsoft’s Remote Desktop Connection and the Keithley …
Spread Spectrum Clocking (SSC) is a highly effective technique utilized to reduce electromagnetic interference or EMI. PCI Express 5.0 System designers use this tool to reduce the adverse effects on adjacent circuits and to pass FCC or other regulatory body requirements for EMI emissions. Manifestations of EMI can result in performance degradation and loss of digital information. Validation of …
