The fast Fourier Transform (FFT), added to an oscilloscope or digitizer, permits measuring the frequency domain spectrum of the acquired signals. This provides a different and usually helpful ...

We investigated the vibrational dynamics of proteins in amorphous hydrated films of lysozyme and myoglobin using polarization-selective time-domain Raman spectroscopy. The anisotropic spectra for ...

Terahertz techniques encompass a set of experimental and analytical methods that generate, manipulate, and detect electromagnetic radiation in the terahertz (THz) frequency range, typically 0.1–10 THz ...

Tektronix, Inc. introduced the world's first mixed domain oscilloscope (MDO) that delivers the functionality of an oscilloscope and a spectrum analyzer in a single instrument. The new MDO4000 Mixed ...
