Enhance EMC Testing with Digital IF

Modern electromagnetic interference (EMI) receivers and spectrum analyzers used for compliance and precompliance testing employ digital intermediate-frequency (digital IF) processing technology for signal analysis. Not only does digital IF boost overall instrument reliability, it enables improved amplitude accuracy, increased measurement throughput, and reduced dependence on operator experience level. These benefits result in higher efficiency and lower operating costs. This article discusses the differences between analog and digital IF architectures, and how digital IF enhances both compliance and precompliance measurement processes.

Radio Relays Improve Wireless Products

In order to transmit communications through Earth’s atmosphere, satellites and space vehicles need radio equipment that can operate at higher frequencies than on Earth. These higher frequencies, until recently, have demanded mechanical switches in radio relays. Unfortunately, the mechanical switches had some problems with frequency routing, which inspired NASA to seek more rugged, reliable solutions.
