The MAXEYE Technologies Signal generation software is an ideal test tool for generating test signals with different configurations and under different conditions. It can be used to completely test the receiver so as to characterize its performance during design, verification and manufacturing.The receiver's performance can be verified by analyzing BER at various stages.

This toolkit offers a standards-based test solution for designing, evaluating, and manufacturing AM/FM/RDS receivers. Radio Data System (RDS) is a communications protocol standard for transmitting digital information in traditional FM radio broadcasts.

RDS standardizes several types of transmitted information, including time, station identification, and program information. RDS is also used for transmitting traffic information using Traffic Message Channel.

RDS Messages

The following are the RDS Messages supported by the toolkit. The toolkit allows user to configure the complete set of parameters required for RDS Message.

• Basic Tuning and Switching Information: Allows a radio station to transmit Traffic Announcement, Music/Speech Switch Code, Tuning Frequency,Alternatuve Frequency and Program Service Name of the Broadcasting Station.

• Programme Item Number and Slow Labelling Codes: Allows a radio station to transmit Programme Item Number, Extended Country Code, Language Code and Linkage Actuator. Day, Hour and Minute collectively forms the Program Item Number (PIN). PIN specifies the scheduled broadcast start time.

• Radio Text: Allows a radio station to transmit upto 64-character free-form text that can be either static (such as station slogans) or in sync with the programming (such as the title and artist of the currently playing song).

• Radio Text: Allows a radio station to transmit upto 64-character free-form text that can be either static (such as station slogans) or in sync with the programming (such as the title and artist of the currently playing song).

• Clock Time and Date: This message type can synchronize a clock in the receiver. The transmitted clock-time and date shall be accurately set to UTC plus local offset time. Otherwise the transmitted CT codes shall all be set to zero.

• Traffic Message Channel: This message type allows communication of traffic events, such as accidents and queues to user. If there is any traffic incident in the current route, then the TMC information is used for calculating and suggesting alternate routes.

• Enhanced other networks (EON): This feature can be used to update the information stored in a receiver about program services other than the one received. Alternative frequencies, the PS name, Traffic Program and Traffic Announcement identification as well as Program Type and Program Item Number information can be transmitted for each other service. The relation to the corresponding program is established by means of the relevant Program Identification.

MAXEYE Technologies provides generation functions in LabVIEW and C for generating the standard complaint signals for various digital audio and video broadcasting standards. The Getting Started Guide explains how to use the AM/FM/RDS/TMC Signal Generation Toolkit with the programming examples and Soft Front Panel (MaxEyeAM/FM/RDS/TMC Signal Generator) by using the NI Vector Signal Generator (NI VSG), Vector Signal Transceiver (NI VST), and Universal Software Radio Peripheral (NI USRP).
