Permanent Link to Multi-Channel RF Recorder
Averna, developer of test solutions and services for communications and electronics device makers, announces the availability of a field-ready multi-channel RF Recorder for RF applications covering 330 MHz to 2.5 GHz. The Averna RP-5300 RF Recorder is an advanced tool for both field testing and performance testing, Averna said. With 50 MHz of recording bandwidth at 16-bits, it can record multiple GNSS signals in up to two bands (L1, L2, L5), such as GPS or GLONASS. Its compact size and integrated display was designed for field operation. Wireless products need to perform well in the complicated and difficult-to-predict RF environments found in the real world. Simulators can bring the design up to a certain point in the development process, but Averna’s RF Recorder captures all the multi-path, interference and general degradation of signals that end-users will experience. Capturing the segment of spectrum of interest, from minutes to hours, allows a technician to return to the lab with data necessary to diagnose and solve the problem, while building a library of environments to harden their products for the future, Averna said. “Recording live, impaired, RF signals of interest in the field, without demodulation or alteration, reduces the need for traditional field-testing of RF receivers,” said Brendan Wolfe, director of product management at Averna. “We are thrilled to bring to the GNSS market a portable and high-fidelity multi-channel RF recorder designed for the optimal capture of real-life RF environments.” The RP-5300 comes preloaded with Averna’s RF Studio Recorder. RF Studio is workflow software for making trouble-free RF recordings, managing collected data, and analyzing or playing back collected RF environments. With RF Studio Recorder, the intended signals are captured during and after a recording session without the need for RF experts on site, Averna said. Key features include: 50 MHz recording bandwidth to capture multi-GNSS signals Two channels to capture signals operating at different frequencies Up to 11 hours of recording time with external RAID (2×50 MHz channels @ 16-bit-depth) Field-ready with an integrated touchscreen display, ruggedized chassis and compact size Simple field setup, intuitive user interface and test-case profiles For customers interested in a complete solution of RF recording to playback, Averna recommends the Averna RP-5300 Series be paired with the Averna URT-5000, a world-class RF Player and Signal Generator.
