The Oscillator Offset Reduction group box allows the user to govern the behavior of the internal crystal oscillator The Off radio button means that the oscillator frequency offset reduction mode is turned off The Freq Locked radio button means that the receiver will adjust the internal oscillator s frequency until the measured frequency offset is reduced to zero By using the incoming satellite signals the receiver will force the internal oscillator to generate a very stable 20 MHz frequency signal This frequency output is available via the corresponding receiver output pin The user is able to monitor the offset reduction in the Clock offset field of the GEO tab After selecting Freq Locked the value in Clock offset starts to reduce and soon usually in a few minutes it will become equal to zero while in contrast Osc Offset will not change much The Freq and Time Locked radio button means that the receiver will adjust both the internal oscillator s frequency until the measured frequency offset is reduced to zero and the internal clock until it gets fully synchronized with the specified reference time scale Switching from Freq Locked or Freq and Time Locked to Off may result in a temporary loss of lock to satellites Freq Locked guarantees that the receiver s 20 MHz output will have long term stability not necessarily short term stability However there 2 64 PCView Software Manual www javad com www javad com
