Spectrogram is one of the many unique functions developed by Promax, that helps to find problems in TV distribution systems. The spectrogram is a graphic that shows frequency in the vertical axis, and time in the horizontal axis. Signal levels are then displayed using different colors. Warm colors are used for high signal levels. Cold colors are used for the low signal levels. Exclusive for your TV EXPLORER II and TV EXPLORER II+ from PROMAX.
