FM Band Spectrum & Mod Analyzer, RDS/RBDS Decoder-Reader
The Band Scanner Pro is a pocket - sized FM modulation analyzer that possesses all the features that one could possibly need to look at the FM broadcast band. The Band Scanner Pro can be used to evaluate FM broadcast band congestion and to log station identification parameters. This product can measure the RF level, MPX deviation, Left & Right audio levels, RDS and Pilot injection levels.
This easy-to-use device presents you with the opportunity to view the network parameters of your and your competitors’ stations, to export playlists to Excel file, and to compare the signal strengths of these stations. The supplied – free of charge Windows software sweeps the across the FM band, logging every carrier and generating a spectrum display of carrier level vs. frequency. It then analyzes each carrier and creates a station list. Stations with an RDS presence are further refined to show all the radio data groups that have been transmitted.

This is a tool to evaluate FM broadcast band congestion and to log station identification parameters. The "Band Scanner Pro" can measure RF level, MPX deviation, Left & Right Audio levels, RDS and Pilot injection levels. The system is powered by the USB port of any Windows PC. Supplied free of charge Windows software sweeps the receiver across the FM band, logging every carrier and generating a spectrum display of carrier level vs. frequency. It then analyzes each carrier and creates a station list. Stations with an RDS presence are further refined to show all the radio data groups that were being transmitted. Its interface resembles a portable radio's: It may be tuned manually through the receiver screen or by double-clicking a point on the spectrum plot or on an entry on the station list. Spectrum plots may be saved as jpg or bmp files. The RDS data error level is graphed in a separate window on the receiver screen. The program can be monitored with headphones plugged into a standard 1/8" jack.

What does (same) and (reg.) mean in the RDS AF List?
This is a citation from US RBDS Standard/EN 50067 standard:
Method B AF coding is used where it is required to indicate frequencies that belong to different regions, which may carry different programs.
For the transmission of the frequency pairs within one block the following convention is used:
- They are generally transmitted in ascending order, e.g. 89.3 - 99.5 or 99.5 - 101.8 F1 < F2
- In special cases they are transmitted in descending order, if they belong to different regions, or carry from time to time different programs, e.g. 99.5 - 90.6 or 100.7 - 99.5 F1 > F2
Examples of a AF method B coding:
F1 F2 Commentary #11 89.3 Total number (11) of frequencies for tuning frequency (89.3) 89.3 99.5 F2 > F1 hence 99.5 is an AF of tuned frequency 89.3, and it is the same program 89.3 101.7 F2 > F1 hence 101.7 is an AF of tuned frequency 89.3, and it is the same program 88.8 89.3 F2 > F1 hence 88.8 is an AF of tuned frequency 89.3, and it is the same program 102.6 89.3 F2 < F1 hence 102.6 is an AF of a regional variant of tuned frequency 89.3 89.3 89.0 F2 < F1 hence 89.0 is an AF of a regional variant of tuned frequency 89.3 #9 99.5 Total number (9) of frequencies for tuning frequency (99.5) 89.3 99.5 F2 > F1 hence 89.3 is an AF of tuned frequency 99.5, and it is the same program 99.5 100.9 F2 > F1 hence 100.9 is an AF of tuned frequency 99.5, and it is the same program 104.8 99.5 F2 < F1 hence 104.8 is an AF of a regional variant of tuned frequency 99.5 99.5 89.1 F2 < F1 hence 89.1 is an AF of a regional variant of tuned frequency 99.5 -
Why upon installation of the software, the USB green LED on the unit is flashing rapidly?
Green flashing LED indicates that Band Scanner Pro has no drivers installed. With a normal installation, the driver will be located here: My Computer/Local Disk (C:)/Program Files/Band Scanner Pro/Drivers. Drivers can be found on the supplied CD also, in the 'Drivers' folder. Driver Installation details are described in DEVA User Manuals, chapter 'Installing the Software'.

How can I reset the data acquisition?
Press the "SET" button. Whenever setting the frequency (same or not) it will clear all of the acquisitions.
