The
following 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 bandwith makes this
receiver particularly suitable for surveillance
and monitoring of civilian and military aircraft
and marine communications.
External
Reference Oscillator Option (G313/XR)
The G313/ER
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).
Intermediate
Frequency Output Option 45 MHz (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 9kHz-30MHz 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 Output Option 10.7 MHz (G313/IF1)
Similar to the
previous option, the G313/IF1 option provides a
wide-band IF output. The difference is that this
option involves an additional down-converter
which converts the 45 MHz IF down to 10.7 MHz.
To order a
receiver with any of the above options, simply
add the option code(s) to the receiver model
number. For example, for a 180MHz receiver with
external reference oscillator, the model number
will be G313i/180/XR. Options can be mixed
together (except the IF options where only one
can be selected, i.e. IF1 and IF4 cannot be
selected at the same time).
