A set of functions are presented for Octave/MATLAB that allow easy, consistent, and properly scaled DFT/FFT analysis of signals and noise. The techniques and functions presented are easily translated ...

Software for Anritsu’s Field Master spectrum analyzer performs uplink interference measurements in 5G and LTE time division duplexing (TDD) networks. This measurement is now included in the analyzer’s ...

With the ever-expanding adoption of wireless in embedded systems of all types, there’s no question that having spectrum analyzer capability in an oscilloscope is a time-savings convenience for ...

Every machine has its own way of communicating with its operator. Some send status emails, some illuminate, but most of them vibrate and make noise. If it hums happily, that’s usually a good sign, but ...

No instrument, whether in the time or frequency domains, is suitable for all use cases. Signal/spectrum analyzers shine for ensuring standards conformity. Oscilloscopes tend to be more versatile, ...

While [Vinod] says he’s not an expert in this sort of thing, we really like his audio spectrum analyzer build from a simple microcontroller and LCD display. It is a well-studied fact that every audio ...

Using a spectrum analyzer to measure noise signals requires several additional factors, such as sensitivity or how well the instrument can measure small signals. The analyzer’s noise floor specifies ...

Near-infrared (NIR) spectroscopy is a rapid, non-destructive method for analysis of products measured routinely that can eliminate lost time and product with real time quality control. This technique ...

It has become harder and harder to assess the real value of a gemstone since the emergence of synthetic diamonds, treated diamonds and nearly perfect imitates. Infrared spectroscopy is an elegant way ...

Explore how Raman spectroscopy supports quantitative pharmaceutical analysis by enabling accurate measurement of active ...
