If you are involved in military, aerospace or defense and have been around radar and communication systems, with high-power RF transmitters and high-gain antennas, you are probably aware of the many risks associated with Radio Frequency Radiation (RFR) Hazards. RF emissions from these systems have the potential to cause catastrophic damage to operations and maintenance personnel, ordnance and …
The wireless spectrum is a finite commodity that is tightly regulated, managed and shared by all nations, manufacturers and citizens, who risk being fined if they are caught operating outside of what's regulated or licensed. The presence of interference or other signals of interest creeping into one's band of wireless spectrum is a daily occurrence to some and is of great concern to many who may …
Tektronix, the measurement insight company committed to performance and compelled by possibilities, celebrates its 75th anniversary of operations. Already well established as a supplier of high-quality test instrumentation in the United States, Tektronix saw the potential of expanding in Europe in the 1950s. With the advent of NATO in 1949 and increasing prosperity as the continent shook off the …
Evaluating and characterizing wideband communications, radar and electronic warfare systems in real time is challenging. Lacking a commercial off-the-shelf (COTS) alternative, some radar test teams stream test data to an inherently non-deterministic computing device such as a PC or laptop, inevitably leading to lost or missing data with no ability to verify that data is being recorded as expected …
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 …
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 …
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 a few short years, the number of drones, or unmanned aerial vehicles (UAVs), purchased has soared. In the US alone, the FAA projects the small model hobbyist UAV fleet will more than double from an estimated 1.1 million vehicles in 2017 to 2.4 million units by 2022. Worldwide, Teal Group’s World Civil UAS Market Profile and Forecast projected in 2018 that non-military UAS production (Commercial …
Oscilloscopes measure the voltage of an electrical signal, which is then graphically represented by waveforms. However, an oscilloscope can be used to take measurements for a number of different applications – one of which is frequency. But how does an oscilloscope measure frequency, exactly? Well, there’s a straightforward answer, and then there’s a slightly more complicated answer.
On most, if …
