Appendix G – Hardware Options
Numerous factory-fitted hardware options are available for the G315 receiver.
Please note that some of these options are for OEM applications only and may
not be available in your location. Please check with your dealer regarding
availability.
External Reference Oscillator Option (G315/XR
)
The “XR” option, available only for the G315i model, 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 input is AC-coupled,
has 150 ohm impedance, and expects the external reference signal to be a
sine or square wave, in the range of 100 mV to 5 V peak-to-peak.
To select the external reference frequency, the following command-line
software switch is used:
/c
This switch disables the internal reference oscillator and defines the frequency
of an external reference oscillator. The external reference frequency can be in
the range of 8 and 20 MHz. For example, if the external frequency is
16.7890124 MHz, this would require the following command-line switch:
/c16.7890124
To apply the command-line switch, you can either type the name of the
application in the Windows Run Program edit box, followed by the desired
command-line switch. Alternatively, you can right-click on the G315i receiver
desktop icon, select
Properties
, and add the command-line switch to the
Target.
For example, for external reference 10 MHz, the command-line switch would
be as follows:
"C:\Program Files\WiNRADiO\G315\WRG315.exe" /c10
