DeskLab RDS – Multichannel RDS Encoder

RDS

It is essential in the development of any RDS capable FM receiver to fully validate the reception characteristics in as many real-world situation as possible. This is difficult to achieve with a receiver designed for use in a static location, but becomes far more complex when the receiver is moving such as is encountered with automotive products. Typically this involves extended periods of on-road testing across multiple countries to ensure good coverage of likely scenarios.

Ideally, it would be possible to recreate these situations in the development environment, allowing better testing throughout the process and reducing the amount of expensive on-road testing. The DeskLab RDS is specifically designed to assist engineers in this process by providing 8 individually controllable FM/RDS channels, providing a rich environment to emulate real situations without leaving their desks.

Key Features

  • Powerful 8 Channel FM/RDS Generator
    • All channels independently configurable and controllable
    • Supports RDS (Radio Data System) and RBDS (Radio Broadcast Data System)
    • Onboard processor offloads RDS management from host computer
    • Overall RF output level can be controlled over a 60dB range in 0.5 dB steps
    • Controllable from a Windows computer via a standard USB-2 link
  • Per Channel Features
    • Transmit frequency adjustable from 76MHz to 108 MHz with 50kHz resolution
    • Channel RF output level can be controlled in the range 15 to 70 dBuV in 0.5 dB steps
    • Generates stereo audio and RDS multiplex
    • Supports all RDS group types in an arbitrary sequence
    • Can dynamically switch between multiple group sequences
  • Audio Capabilities
    • External stereo audio inputs on 2 channels
    • Onboard mono/stereo DDS tone generation on all channels (500Hz -15kHz)
    • Arbitrary waveform replay (1 stream transmitted on 1 or more channels)
  • Application Software
    • DeskLab Explorer provides a GUI driven configuration interface
    • DeskLab Script allows the creation of complex, dynamic scripted tests
    • Software supports Windows 7, 8.1 and 10
    • Custom application integration possible via SDK

Typical Applications

  • Fully automated FM/RDS receiver testing
  • Multi-station AF switch simulation
  • Checking of TA handling
  • Tunnel entry/exit requrements validation
  • TMC message generation to exercise navigation systems
  • Replication of real-world RDS scenarios
  • DAB-FM link testing
  • And many others…
