global radio frequency (RF) test equipment market is expected to reach US$ 5.2 billion by 2030, with an annual growth rate of more than 7.0% WILMINGTON, DELAWARE ...

Implementation of the 5G radio frequency (RF) standard is increasing rapidly [1]. Over the past four to six quarters, there has been an increased focus on publications and products that have been ...

Rheumatoid factor (RF) is a type of antibody, an immune system protein that helps the body fight foreign substances like bacteria and viruses, called antigens. Antibodies, also known as ...

One very successful trick I use to simulate radiated immunity on the bench is to run an RF generator into an H-field (loop) probe. The best level seems to be +15 to +20 dBm. This will generate an ...

The test economics of state-of-the-art smartphones, tablets and routers demand highly parallel RF test. We are addressing this next wave in RF communications test, enabled by Wi-Fi 6E, operating in ...

Developing an automated production test solution for current and next-generation complex RF SIP/SOC devices is an increasingly difficult task. Both the test program and the device interface board (DIB ...

Emerson, which acquired National Instruments (NI) a couple of years ago, has made hardware and software enhancements to NI’s PXI portfolio to address the growing complexity in radio frequency (RF) ...

When persistent joint pain strikes, the search for answers often leads to a crucial diagnostic tool: the rheumatoid factor test. This relatively quick blood analysis serves as a window into the immune ...

This is the second article of a three-part series discussing the likely impacts of next-generation consumer wireless semiconductor devices on instrumentation performance requirements. The first ...

Measuring RF power at high frequencies is tricky. What if one sensor could cover it all, cut test time, and simplify complex ...
