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/XR receiver includes an additional external SMA connector, which can be used to connect an external reference oscillator for the highest possible frequency accuracy. This external oscillator can be any frequency from 8 to 20 MHz (the user specifies this frequency via software). The input is available at an additional SMA connector, it is AC coupled and has an internal impedance of 150 ohm. The reference oscillator signal can be either sine or square wave between 100 mV to 5 V peak-to-peak.
