5.10.1. RSSI/SNR Graphing Utility
The Graphing utility Window  RSSI/SNR Graph provides a scan of user selectable metrics versus frequency.
Graphing options include RSSI, SNR, Low Adjacent Channel Strength (LASSI), and High Adjacent Channel
Strength (HASSI). These metrics can be individually selected for display. A line or bar graph style can be chosen
and markers indicating valid stations and their frequencies can be displayed. Once the preferred graphing and
displays have been selected, click the “Draw” button.
Figure 27 shows an example scan in the FM band. Stations above the red line meet the RSSI threshold for valid
stations. The SNR page shows a complementary scan of SNR values across the band as well as the SNR
threshold for valid stations.
