  • .ultrasync: The ROSc:OUT:ULTRAsync command.

source property 

source: RoscSource

Return the ROSc:SOUrce command.

Description
  • This command sets or queries the selected source for the time base reference oscillator. The reference oscillator locks to this source. Depending on the command argument that you specify, you can use an external reference or use the internal crystal oscillator as the time base reference. This command is also useful for synchronizing multiple instruments.
