Patent ID: 8018459

Claim:
A system for calibrating broadcast signal transmission equipment, comprising: a processing device; a user control device operatively connected to said processing device; and a display operatively connected to said processing device, 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 said 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; said point corresponding to said first amplitude; said radial axis connecting the center of said circle and a first one of said labels corresponding to said first frequency.
