Self-diagnostics with BIT and thermal management

The WiNRADiO WR-G66WSBe is a top-performance, direct-sampling, low-power, software-defined receiver, designed for sonobuoy telemetry operation, covering the entire sonobuoy frequency range without the need for hardware re-tuning. 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.

WR-G66WSB Sonobuoy Receiver

The WR-G66WSBe receiver is supplied with Windows based application software. A programmer's API is available upon request, suitable for integration in custom designed sonobuoy systems.

Software

(Click on panel to enlarge.)

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).

Alternative versions

Alternative versions of this receiver exist in different form factor and with different interface types, also offering extended operating temperature and mechanical mounting methods.
