THE BANDSCANNER™ UTILITY
The 541 BandScanner is an annotated RF spectrum analyzer
utility that is able to graphically display the entire FM band.
From the front panel,
BandScanner
is found under
Graphs
.
Warnings!
1) Band-scanning interrupts all mod-monitor functionality dur-
ing the scan cycle, as it essentially tunes across the band
and collects data from each station in the market. Program
audio outputs are muted, and scanning will temporarily in-
terrupt the history studies.
2) Keep in mind that once the display is presented, clicking on
a bar will immediately tune the 541 to that station, which
you may not want to do.
Shown above is an entire FM-band plot of the busy Los Angeles
FM market. Two
Scan Type:
modes may be selected at the bot-
tom of the screen. RSSI is the quickest scan, but will show only
RSSI signal levels. But the 541 can also scan and display both
RSSI + RDS information, which will take a bit longer.
Start Scanning
To start a band scan, click the Scan bar at the bottom. Step
Size:
defaults to 200kHz; 100kHz steps are also available.
In the example scan, every FM carrier found is represented by a
vertical yellow bar. Bar height indicates signal strength in dBµV
per the annotation along the left edge. The example is an
RSSI
+ RDS scan. Had it been run in the simple RSSI mode, all sta-
tions would show up as yellow bars without the red dots.
