"Signal Averaging" is utilized in manifold applications in which the demand on resolution and accuracy cannot be reached due to random noise and a poor signal-to-noise ratio (SNR). If a repetitive signal is being acquired multiple times (several exactly triggered scans in a row) averaging of those scans can nearly eliminate single peaks and white noise while preserving the original signal shape, amplitude, phase, peaks etc. The SATURN FastScan Option makes use of this technology and implements it into the hardware logic of a SATURN Transient Recorder. This leads to a significantly enhanced resolution and improved dynamic range for use cases which require high acquisition rates.
