Description of command

FW vers.

The command defines the source of the synchronization signal. After activating the external reference frequency (e.g. after a reset of the base system where the reference frequency is set to INTernal) it is necessary to allow for a setting time (~1 s) until the CMU has synchronized. The query [SENSe:]SYNChronize:FREQuency:REFerence:LOCKed? indicates whether the reference frequency is locked. A partial reset of all function groups with the exception of the base system does not reset the source of the reference frequency.
