WR-G313i Receiver Options The following factory-fitted hardware options are available for WR-G313i
receiver:
Frequency Extension Option (G313/180) The G313/180 option extends the frequency coverage from the
standard 9kHz-30MHz to 9kHz-180MHz. This makes it possible to use this receiver for narrow-band
communications in the low VHF range. The receiver's variable IF bandwidth makes this receiver particularly
suitable for surveillance and monitoring of civilian and military aircraft and marine communications.
External Reference Oscillator Input Option (G313/XR) The G313/XR option adds an external SMA connector
to the receiver board, 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).
Reference Oscillator Output Option (G313/RO) The G313/RO option adds an external SMA connector to the
receiver board, 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.
Intermediate Frequency 45 MHz Output Option (G313/IF4) The G313/IF4 option adds an external SMA
connector to the receiver board, which provides a wide-band IF output of the entire 9 kHz - 30 MHz input band,
up-converted to 45 MHz (i.e. 9 kHz corresponds to 45.009 MHz, 30 MHz corresponds to 75 MHz). This makes
it possible for the receiver to be used as a front-end tuner for HF monitoring systems requiring the capability of
digitizing the entire HF band instantaneously; or a front-end for a spectrum analyzer, taking advantage of the
receiver's excellent sensitivity and low noise-floor level.
Intermediate Frequency 10.7 MHz Output Option (G313/IF1) As an alternative to the previous option, the
G313/IF1 option provides a wide-band IF output. The difference is that this option involves an additional internal
down-converter which converts the 45 MHz IF down to 10.7 MHz.
