GSS6300, SimCHAN: Why do I get error message 'Reference frequency not locked, GSS6300 serial # 6xxx'

Environment/Versions
  • SimCHAN
  • GSS6300
  • GSS6300M
  • GSS6300Mi
  • Dual box configuration
  • External reference connected
Answer
  • There are 2 main causes of this error message
  1. There is no cable connected between the Master and Aux 'expansion port'
  2. An external frequency has been supplied to both the Master and the Aux unit.

 

  • The correct setup is:
    • External frequency, if used, connect to 'EXT REF IN' of the Master unit ONLY
    • Cable connected between Master and Aux 'Expansion port'
  • DO NOT CONNECT EXTERNAL REFERENCE TO BOTH UNITS!
