SMW-K703 option (100 MHz, 1 GHz reference input/output)
When this option is installed, the 1 GHz low noise input and output for synchronization can be used.
In WIDE mode, the signal generator will use this signal directly as a reference for the synthesizer.
This option should be used if a very high phase stability between multiple generators is required.
The 100 MHz low noise input and output mode is only available with this option.
R&S
®
SMW-K704 option (flexible reference input)
When this option is installed, the reference input frequency can be set in 0.1 Hz steps from 1.0 MHz to 100 MHz.
The signal generator will lock its internal reference oscillator on the input frequency.
Note on choosing the proper reference synchronization bandwidth.
The user has the choice to set the synchronization bandwidth either to NARROW or WIDE.
In WIDE mode, the best possible phase stability is achieved.
The phase noise performance close to the carrier depends on the phase noise of the external signal source.

SMW200A Vector Signal Generator 13
In NARROW mode, the reference PLL acts as a clean-up-loop in which the phase noise is mainly determined by the signal generator’s
internal reference source.
This mode is recommended when using external reference sources with close-to-carrier phase noise worse than the R&S

(i. e. rubidium standards).
Note that due to the slow synchronization, reference locking can take up to 10 s.
