Reference Frequency Input
The R&S
FSV/A can use the internal reference source or an external reference source
as the frequency standard for all internal oscillators. A 10
MHz crystal oscillator is used
as the internal reference source. In the external reference setting, all internal oscillators
of the R&S
FSV/A are synchronized to the external reference frequency.
External references are connected to one of the REF INPUT or the SYNC TRIGGER
connectors on the rear panel.
Note:
The optional, and more precise OCXO signal can replace the internal reference
source.
The default setting is the internal reference. When an external reference is used, EXT
REF is displayed in the status bar.
The following reference inputs are available:
