The following factory-fitted hardware options are available for the WR-G65DDCi receiver:
External Reference Oscillator Input Option (/XR)
The G65DDCi/XR option includes an additional SMA connector, which can be used to connect an external 10 MHz reference oscillator for the highest possible frequency accuracy. The reference oscillator can be either sine or square wave between -5 dBm to +10 dBm.
Reference Oscillator Output Option (/RO)
The G65DDCi/RO option includes an additional SMA connector, which can be used to produce an output of the 10 MHz reference frequency. This is useful for situations where the receiver's internal oscillator is to be used as a reference for other equipment. The output is AC coupled, clipped sine-wave at +5 dBm @ 50 ohm.
