Spectrogram: Spectrum waveform monitoring

Example of Spectrogram

The Spectrogram function (patented function), similarly to Merogram, has been designed to detect problems that affect spectrum analyser display only in the form of unpredictable random bursts.




The Spectrogram is a graphic that shows time in the horizontal scale and the measured frequency span on the vertical scale. Signal levels are then represented by colours.

Colour spots on the graphic mean substantial signal reception variations that may be difficult to read otherwise.

The Spectrogram function, unlike Merogram, can be used for all sorts of signals within the frequency range of the TV EXPLORER HD+ not being limited by their modulation scheme.
