Abstract
The present disclosure relates to broadcast signal calibration devices and methods. A system is provided that permits calibration or tuning of broadcast signal transmission and reception equipment through the use of visual representation of test signals. The generated visualizations, incorporating color and shape, are examined to determine whether any adjustments to the broadcast equipment are needed to compensate for equipment age, deterioration, and the like.
Claims1
A system for calibrating broadcast signal transmission equipment, comprising:
- a processing device;
- and
- a display,
- wherein:
- said processing device executes computer readable code to create a first visual representation of a first calibration signal for output on said display;
- wherein:
- said first visual representation is generated according to a method comprising the steps of:
- (a) labeling the perimeter of a circle with a plurality of labels corresponding to a plurality of frequency bands, such that moving radially inward or outward from any one of said labels represents a change in a signal amplitude at the frequency corresponding to said one of first labels;
- (b) identifying a first occurrence of a signal having a first amplitude at a first frequency;
- and
- (c) graphically indicating a point along a radial axis corresponding to said first amplitude;
- said radial axis connecting the center of said circle and said first label.
