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 ...

A rheumatoid factor test checks for an antibody that can be a marker for rheumatoid arthritis. It is one part of diagnosis. Not everyone with a positive rheumatoid factor blood test has rheumatoid ...

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 ...

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 ...

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 ...

Next-generation wireless applications are increasingly coping with new requirements for latency and higher data transmission rates, leading RF engineers to confront new test challenges at the ...

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 ...

Spirent’s James Kimery spoke with EEWorld on how testing Wi-Fi devices is becoming more of an end-to-end experience. The RF is mature; it’s time to move on to performance testing.
