The WiNRADiO WR-G315e is a high-performance VHF/UHF receiver with a USB interface, extending up to 8599 MHz with additional accessories. It caters to various sectors like government, military, security, and broadcast monitoring. The SDR architecture, dynamic range, and sensitivity provide flexibility. The receiver connects to a PC via USB and features on-board DSP for signal processing. It offers features like spectrum analyzers, calibrated S-meter, and multi-channel control.

The WR-G315e software offers advanced features such as scanning options, squelch types, tuning flexibility, and memory capacity. It includes demodulation modes, variable IF bandwidth, spectrum analyzers, noise blankers, and notch filters. The receiver allows audio recording, IF spectrum recording, and signal analysis for optimal reception. Professional instrumentation features like frequency accuracy measurement, audio spectrum analyzer, and real-time spectrum display enhance its capabilities.

The standard WR-G315e package includes the receiver, application software, user manual, power supply, antenna, USB cable, and adapters. System requirements include a PC with a 500 MHz Pentium CPU, a free USB socket, and compatibility with Windows XP, Vista, 7, or 8. The optional Wide FM mode provides wide-band FM demodulation capability through a hardware-defined receiver, enhancing the receiver's functionality for wider frequency coverage.

The receiver type is DSP-based SDR with DDS-based dual-conversion superheterodyne front end. It covers a frequency range of 9 kHz to 1800 MHz, expandable to 3500 or 8599 MHz with an optional AMFE unit, excluding cellular radiotelephone frequencies as required by law. The tuning resolution is 1 Hz, and it supports various modes, including AM, AMS, LSB, USB, DSB, ISB, CW, FM, and wide-FM, with an optional WFM demodulator. It offers image rejection ranging from 60 dB to 50 dB across different frequency ranges, IP3 of 30 dBm at 20 kHz, spurious-free dynamic range of 90 dB, MDS of -135 dBm, and phase noise of -148 dBc/Hz at 100 kHz. The internal spurious level is typically less than the equivalent antenna input of -105 dBm, with RSSI accuracy of 2 dB, RSSI sensitivity of -137 dBm, and adjustable bandwidth from 50 Hz to 15000 Hz in 1 Hz steps (230 kHz for WFM option). 

The scanning speed is 50 channels/s, and sensitivity varies for different modes and frequency ranges. It operates with intermediate frequencies of IF1 at 109.65 MHz and IF2 at 16 kHz, utilizing a 2 x 4-pole 20 kHz crystal roofing filter. The tuning accuracy is 1 ppm, frequency stability is 0.5 ppm, and it has a 50 ohm SMA connector for antenna input with a maximum input level of +18 dBm. The output includes digitized IF and audio signals over a USB interface. The dimensions are 166 mm (6.5") in length, 97 mm (3.8") in width, 41 mm (1.6") in height, and it weighs 430 g (15.1 oz).
