Tektronix, Inc. announced a new software option for its OM4000 optical modulation analyzer series that offers automated test support for 400G multi-carrier coherent optical modulation. This software ...

Modulation is fundamental to electronic communications. The modulating signal might be analog in nature (voice or music) or digital bit streams. Most modern communication systems are digital, using ...

The distribution of content involves the need to adapt digital information to its means of carriage — what we typically call transmission — and to understand that fully, we need to understand the ...

Fiber-optic interferometric sensors have emerged as essential tools in precision measurement, utilising the interference of coherent light to detect minute displacements and variations in physical ...

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 ...

It was once a strongly held opinion that there were only four types of effects processors. There were those that affect frequency, those that affect time, those that affect amplitude, and those that ...

The AMMA-2, the new digital AM modulation monitor from Belar, may look like an ordinary piece of broadcast equipment. It’s one rack unit tall and has the typical buttons and LEDs on the front panel.

We’ve been loving the variety of entries to the 2025 One-Hertz Challenge. Many a clock has been entered, to be sure, but also some projects that step well outside simple timekeeping. Case in point, ...

March 13, 2013. Tektronix Inc. today announced a new software option for its OM4000 optical modulation analyzer series that offers automated test support for 400G multicarrier coherent optical ...
