11 - LabSat3W External Reference Clock Input

LabSat 3 Wideband features an external reference input for synchronization to a 10 MHz clock. To use this feature, connect a 10 MHz reference signal with minimum +3 dB level to the REF IN SMA connector and ensure that the 'External 10MHz' reference clock option is ticked in Menu > Setup > CLK REF > External 10 MHz.
 

When Labsat is operating from the internal TCXO or OCXO, the REF connector can be configured to output a 10 MHz reference for use by other equipment. This is enabled by ticking the REF OUT menu option which is visible only when internal TCXO or OCXO is enabled.
