Single Channel - RTA and more

Single channel spectrum measurements are signal analysis measurements because all they can tell you is the frequency content and amplitude of a signal. Real-time spectrum analyzer (RTA) and Spectrograph displays are based on single-channel FFT analysis.

Single-channel spectrum measurements allow you to examine the spectral content of audio signals throughout a system. Spectrum measurements are extremely useful in many applications, including the identification of feedback frequencies in sound reinforcement systems, noise and sound exposure measurements, and general signal monitoring tasks. Data from spectrum measurements can be displayed as a conventional RTA (real-time spectrum analyzer) graph or plotted over time in a three-dimensional (level vs. frequency vs. time) Spectrograph chart.
