| Description: |
Screenshot showing channels received (columns) by antenna direction (rows). Each map location represents analog signal strength in blue, ATSC modulated (8vsb) signal quality (SNR) in green, and digital symbol quality in red, thus viewable DTV signals appear on a spectrum from red (weak) through pink (medium) to white (strong). Blue areas of the map show signals too weak to obtain a signal lock or non-DTV signals.
The stripchart shows signal strength (top - blue), SNR (middle - teal), and symbol quality (bottom - yellow) as the tuner scans through the specified channel range. The stripchart can also be used to monitor signal quality while aiming the antenna for a single channel. |
