New National Instruments Hardware and Software Provide Dramatic Advances from Baseband to RF Engineers and scientists now can generate RF and baseband signals more than 300 times faster with the new ...

RF signals historically are measured using spectrum analyzers, at least that was before oscilloscopes offered sufficient bandwidth for those measurements. With oscilloscope bandwidths over 100 GHz, RF ...

In Part 3 of RF Fundamentals, we will focus on the challenges related to the need to generate and demodulate analog and digitally modulated signals in the RF signal chain. We’ll review CW signal ...

A signal generator, a general-purpose piece of test equipment, performs numerous measurements for a variety of applications requiring electromagnetic wave signals as stimuli. Its roots trace back to ...

Tektronix has rolled out the RTX130A, an integrated MPEG and RF signal generator offering both unmodulated and RF modulated playout of MPEG transport streams, supporting both cable (QAM A, B & C) and ...

As the number of higher-throughput applications grows, so does the need for wider bandwidth and network coverage in wireless systems. Given limited spectrum allocation, wireless communication ...

Compared to the simple diode needed to demodulate AM radio signals, the detector circuits used for FM are slightly more complicated. Wrapping your head around phase detectors, ratio detectors, ...

Raspberry Pi enthusiasts searching for a way to use their Raspberry Pi mini PC with an old school retro TV, may be interested in the Raspberry Pi Zero RF Modulator HAT. Using old now-defunct TVs and ...

Most of us know that to get the best possible WiFi signal, you want there to be as few walls as possible between you and the Access Point. But that might soon change, as researchers at MIT have found ...
