The WiNRADiO WR-G315i is a software-defined high-performance VHF/UHF receiver (9 kHz to 1800 MHz, extendable to 3500 MHz using an optional Antenna Multiplexer and Frequency Extender) on a PCI card.
This receiver is intended for government, military, security, surveillance, broadcast monitoring, industrial and demanding consumer applications.
The receiver offers an unparalleled flexibility given its SDR architecture, respectable dynamic range, and high sensitivity. Many useful features complement the receiver, making it capable of filling not only the role of a monitoring receiver but also that of a measuring receiver, such as the calibrated S-meter showing the received signal levels in dBm, µV or S-units, down to the -140 dBm noise floor, several spectrum analyzers, and many other features not usually found on receivers of this price.
The hardware and software package consists of the receiver card, Windows-based software, a start-up antenna and a user’s manual.
The G315i/RO receiver includes an additional external SMA connector, which can be used to output the internal reference frequency. This is useful for situations when the receiver’s own internal oscillator is to be used as a reference for other equipment, or, if an external reference is used, to provide this external reference to other receivers in a daisy-chain arrangement. If the receiver relies on its internal reference oscillator, this option will provide 16.384 MHz reference output. If an external oscillator is used, then the external oscillator frequency will be provided at this output. The output is at an additional SMA connector, DC coupled, sine-wave at HCMOS levels (i.e. approx 0.6 to 4 V peak-to-peak) with an internal impedance of 150 ohm. It can be directly connected to an external reference oscillator input of another WR-G315i receiver.
