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 ...

Suddenly, we seem to have a plethora of low-cost RF signal generators available for the RF experimenter and EMC engineer (refer to References for other low-cost RF generators reviewed). Signal Hound ...

Digital or vector modulation can provide increased spectral efficiency, higher data security, and higher quality communications. This comes at a cost of increased system complexity and a resultant ...

If you’ve ever used an RF signal analyzer, you’re probably used to seeing displays like the spectrum graph or constellation plot. Of course, trusting the answers you get from the instrument often ...

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 ...
