The bright, spatially coherent radiation emitted by a laser can be found in numerous research applications, such as spectroscopy, photochemistry, communications, imaging and material processing.

All periodic signals can be described in terms of amplitude and phase. We all learned that in basic circuit theory. You surely recall having to calculate signal’s phase change when it passed through a ...

Some brief theory and typical measurements of phase noise. Standard analysis of PLL phase noise used by most CAD applications. How to produce the lowest phase noise at a PLL output. A standard design ...

An arbitrary waveform generator (AWG) is a powerful and flexible signal source capable of generating any wave shape within the bandwidth and amplitude range of the generator. Populating an AWG with ...

Just because harmonics is becoming a more prevalent problem, that doesn't mean the subject is getting any easier to understand Harmonics are AC voltages and currents with frequencies that are integer ...

When the arbitrary waveform generator (Arb) was introduced by Wavetek in 1975, a few design and test engineers jumped up and down for joy, but most failed to see the potential of this new signal ...
