Navigator FM is a compact and affordable FM product for easy field surveys as well as on site/studio monitoring of a station’s complete FM signal. The Navigtor is frequency agile and can be set up to measure automatically one or multiple frequencies. It combines in the same unit RF, modulation, pilot, RDS and DARC measurements and analysis.
Broadcasters need to measure their signal in the field, where their listeners are. Navigator 100 makes these surveys easy and fast. We’ve combined a complete RF/Stereo/RDS/DARC measurement system with a sophisticated on-board control computer and GPS receiver, in a ruggedized case.
No other equipment is needed in the field. Measurement campaigns can be completely preprogrammed at the station. The field operator merely has to turn the system on and drive around the coverage area. You can set the Navigator 100 to examine:
- Just your station
- A list of preselected stations
- Every station with an RDS subcarrier
- The entire FM band
Choose Fast Mode to gather RF levels, basic multiplex information, and error rates as quickly as once per second. Or select Slow Mode, and once per minute the system performs a complete analysis, including MPX power and deviation for each subcarrier along with RDS parameters and DARC error rate.
Navigator 100 includes a GPS receiver for mobile RF surveys and a MapPoint DLL for direct exportation and map display. Navigator is the ideal tool to check a signal after repairs or set-up of new equipment at the transmitter site. It enables full AF analysis,Pilot/RDS/DARC/Audio (L+R, L-R, L, R) evaluation and offers various data representations and statistics: such as bargraph, curves and text.
Measurement campaigns are stored on non-volatile Flash Card for easy use. Measurement levels can be read from the front panel or automatically stored on the Flash Card for later use with any PC. Data can be exported into third-party programs such as MapPointTM or Google Earth for automatic mapping of signal parameters. Includes a built-in speaker and headphone jack to verify tuning, plus flexible MPX/composite and data I/O for custom applications.
The Navigator includes MPX/composite signal in/out and RS-232 control for custom applications. You can set your unit to analyze every aspect of a MPX/composite signal for sophisticated sub-carrier balancing, or concentrate on specific parameters for mapping and proof of performance. Every measured parameter and system setting can be accessed from a connected computer, using simple ASCII commands or our FM Explorer software.
