Features:

• 100 MHz, 1 GHz ultra low noise reference input and output option
• For SMB100B
• Enables users to apply a 1 GHz reference signal to the dedicated SMA connector
• The signal generator will lock its internal 500 MHz reference oscillator on the 1 GHz reference
• This option should be used if a very high phase stability between multiple generators is required
• The '100 MHz' input frequency mode is only available with this option - the signal generator will lock its internal 500 MHz reference oscillator on the 100 MHz reference

Extremely good phase stability between multiple R&S SMB100B instruments can be achieved with the optional 1 GHz reference frequency input and output (R&S SMBB-B3 option).

When this option is installed, the user can apply a 1 GHz reference signal to the dedicated SMA connector. The signal generator will lock its internal 500 MHz reference oscillator on the 1 GHz reference. This option should be used if a very high phase stability between multiple generators is required.

Also, the '100 MHz' input frequency mode is only available with this option. The signal generator will lock its internal 500 MHz reference oscillator on the 100 MHz reference.
