The Band Scope feature lets you have the scanner provide a visual representation of radio activity in a frequency band. The screen is arranged with the frequencies increasing in value from left-to-right, and the signal strength for a frequency indicated by a vertical bar that is taller for stronger signals.
This feature allows you to :
- Get a "picture" of spectrum activity across the selected range
- Identify intermittently active frequencies.
- See the relative signal strength of signals in the range
- Check antenna performance
- Check coax quality
- Verify coverage areas
- Identify interference
In use, the scanner rapidly sweeps between the endpoints of the selected frequency range and updates each bar segment with the relative signal strength in each pass. You can use the band scope in normal mode (the bars are all updated with the most recent signal strength) or hold mode (the bars update only if there is a stronger signal than one previously stored for the current position).
