Receivers
The G66WSBi card-based receiver is at the heart of the MS-8132/WSB system. This being a high-performance receiver designed to operate in the harsh electromagnetic environment existing inside a computer-based system and ideally suited for simultaneous multichannel operation.
All 99 sonobuoy channels are monitored simultaneously. Thanks to SDR architecture, the channels are processed instantly in software.
The receiver's hardware offers extremely high dynamic range, high linearity and excellent sensitivity. The input is protected against voltage spikes and excessive power.
The receiver contains a self-diagnostics functionality with BIT (Built-In-Test) and thermal management to prevent damage if environment conditions change out of operational specs.
User interface
The software shows a graphical representation of the receiver (a virtual control panel), making it possible to observe the status of all 99 sonobuoy channels simultaneously at once. The selected channel can be monitored, and the real-time spectrum of the demodulated signal observed.
The audio parameters can be adjusted for the output sound (volume, audio-gain), played on WiNRADiO Digital Bridge™ Virtual Sound Card, and as well recorded to an audio file. The receiver's sensitivity/immunity can be optimized by use of the attenuator and preamplifier.
The software provides an option for distribution of the demodulated audio for up to 32 channels over a computer network using RTP to multiple destinations. The supported RTP audio formats are: linear PCM (16-bit, Mono, 44100 Hz), ITU-T G.711 PCM µ-Law (PCMU), ITU-T G.711 PCM A-Law (PCMA).
