Record & Playback

IZT’s innovative high-performance record and replay system for high-quality RF signals offers customers greatly reduced costs for field-testing, repeatable lab tests, fidelity in reproducing real RF environment and shorter time to market for products.

More about IZT Record & Playback systems

The IZT Record and Replay System is the ideal platform for RF receiver design validation of

  • analog and digital radio,broadcast standards
  • telecommunication systems
  • Global Navigation Satellite Systems (GNSS)
  • and development of automotive carinfotainment systems and chipsets.

The IZT RecPlay system includes a state-of-the-art wideband recorder with integrated high-performance RF receiver and a revolutionary signal generator, which combines 31 virtual signal generators in one platform.

With a real-time bandwidth of up to 25 MHz and a frequency range of 9 kHz to 3 GHz, 6 GHz or 18 GHz, the recorder for example covers the whole FM broadcast band simultaneously in one data stream. An unmatched bandwidth of 120 MHz allows the replay generator to combine multiple recorded and calculated scenarios.

The IZT Signal Suite Data Processor is the associated powerful unique data processing software that allows to review and edit recorded data in offline mode. The IZT Signal Suite Data Processor can be used to extract or combine individual signals from a recording. Various plug-ins of the Signal Suite software enable a big number of software options for your special application.
