RF Record & Playback
The need to design, validate, test and support increasingly complex Navigation as well as Broadcast Radio & Video receivers in an economical and timely manner is an ever-growing concern. We answer that need with the Record and Playback technology.
The RF Record & Playback is a state-of-the-art full band L1, L2, L5 recorder to capture real-world and real-time multi-GNSS signals in the field and replay them in a controlled laboratory environment.
Recording live (impaired) RF signals of interest in the field without de-modulation or alteration extends traditional field testing of RF receivers, by enabling complex field conditions to accurately and consistently be played back in engineering saving additional costly trips to the field to validate engineering changes.
As your library of recordings grows to cover customized reception corner cases, signal playback becomes the tool to implement continuous improvement in product quality by increasing test coverage without increasing time to market through lengthy field trials.
The RF Record & Playback Series is designed to meet the needs of the Global Navigation Satellite System (GNSS) market, where precision and robustness demands a wideband, high dynamic range multi-channel record & playback system.
Now, All GNSS signals in L1, L2 and L5 bands can be processed by 3 record and playback channels. To capture GPS, GLONASS, Galileo and Compass signals in addition to regional systems – synchronously and coherently – a total available bandwidth of 150 MHz becomes a requirement. The system can also capture SBAS signals such as WAAS, EGNOS, MSAS, QZSS, Omnistar, Starfire or other wireless RF signals such as cellular or video.
Building libraries of these real-world recordings allows for repeatable stress testing of relevant conditions necessary to optimize GNSS receiver design.
The dynamic range of the system exceeds 80dB with 16-bit IQ samples for both A/D and D/A converters. Captured data is streamed, in real-time, to a high-capacity RAID system.
The solution is packaged in a ruggedized aluminium chassis, with a pre-amplifier and a DC-to-AC converter for in-vehicle use at 12 volts. The wideband RF record & playback system is the ideal mobile tool for capturing, analyzing and reliably repeating real-world multi-frequency signals.

Conclusion
The RF Record & Playback system is an ideal tool for the development and optimization of HF receivers. It allows real-time recording of various different HF signals in real terms and allows playback of these signals in any laboratory environment for extensive testing of HF receivers.
All signals can be catalogued in user-defined libraries providing a growing repertoire of available testing signals for corner cases.
The system is ruggedized and rather robust and can be connected to a car’s power supply for mobile use. Therefore, it is the ideal solution for mobile recording and subsequent playback of real RF signals.
