New Unit Improves Resolution by 2000 Times, Enabling Engineers to View RF Signal Instabilities and Transients that They Never Knew Existed BEAVERTON, Ore.—Tektronix, Inc., a leading worldwide provider ...
Radio frequency (RF) refers to the part of the electromagnetic spectrum where electromagnetic waves can be generated by alternating current fed to an antenna. It spans from around 3 kHz to 300 GHz. RF ...
Modern oscilloscopes capture, view, measure, and analyze complex RF signals in the time, frequency, and modulation domains. Time-domain analysis, the original oscilloscope function, allows users to ...

Everything you need to know about modulation, from Leslie speakers to vibrato, chorus and BBD chips
In our recent feature on tremolo, we described how a valve can be configured to create a low-frequency oscillator (LFO) that can modulate amplitude. You can’t actually hear the oscillator itself, ...
Active metadevices integrated with semiconductors. (a) Hybrid silicon-metallic resonators for all-optical ultrafast active metamaterials. (b) Broadband metamaterial frequency switch with femtosecond ...
Scientists recently developed a low-power version of the 60 GHz radio frequency integrated circuit (RFIC). The research team said that their RFIC draws as little as 67 mW of power in the 60 GHz ...
Researchers from the University of Rochester and CalTech say they have created the first microwave-rate soliton microcomb that can control the repetition rate at a high speed. Microcombs are frequency ...
