6.10. FM Receiver Logging Tools
The GUI provides several useful logging tools. In the tools menu, user can choose to log raw RDS data, band scan
data, device commands and channel info.
Figure 63. Logging Tools
6.10.1. Log Band Scan
Selecting ToolsLog Band Scan allows you to specify a filename and begin a scan of the entire band for RDS
data, RDS acquisition times, and the contents of each register. The scan feature starts with the first frequency in
the band (CHAN = 0) and then seeks to the first station that meets the seek criteria (SEEKTH, SKCNT, SKSNR).
When a valid station is found, the software waits at the station for the time specified by ViewSession
PreferencesScan Log After Tune Delay (sec) and then checks if RDS is available. If RDS is not available, the
software logs the register settings and seeks to the next valid station. If RDS is available, the software waits an
additional delay as specified by ViewSession PreferencesScan Log RDS Log Delay (sec). When this delay
expires, the software logs the RDS information and register settings and seeks to the next valid station. While
scanning, the software displays a green "Scanning" notice below the menu bar. The scan can be aborted by
selecting the ToolsLog Band Scan a second time. When the scan completes, the filename given is saved in
comma separated format and is available for analysis in a text editor or spreadsheet.
6.10.2. Log Raw RDS Data
Selecting ToolsLog Raw RDS Data prompts for a filename in which all RDS data will be logged in comma
separated format. The software then logs all raw RDS data that is received, the station it is received on, and the
time at which it was received. The logging will continue until ToolsLog Raw RDS Data is selected a second time
at which point the file is saved and available for analysis in a text editor or spreadsheet.
6.10.3. Log Channel Info
Selecting ToolsLog Channel Info prompts for a filename in which all register values will be logged in comma
separated format. The software then logs all register values and the time at which it was received. The logging will
continue until ToolsLog Channel Info is selected a second time, at which point the file is saved and available for
analysis in a text editor or spreadsheet.
6.10.4. Log Device Commands
Selecting ToolsLog Device Commands prompts for a filename in which all software API calls and data with
timestamp data will be logged as text. The logging will continue until ToolsLog Device Commands is selected a
second time, at which point the file is saved and available for analysis in a text editor.
