8 Reference oscillator
The R&S SMB100B is equipped with an internal reference oscillator that generates a
reference frequency of 10 MHz. It is used as internal reference source for the synthe-
sizer.
Alternatively, you can apply an external reference signal. If equipped with the required
options, the R&S SMB100B can process external reference frequency in the range
1 MHz to 100 MHz and the 1 GHz reference frequency.
Regardless of the used reference source (internal or external), the R&S SMB100B
always provides the configured reference frequency at the output. You can use it, for
example to synchronize several interconnected instruments, see Chapter 8.5, "Using
the reference frequency for instruments synchronization", on page 190, for an overview
of typical test situations.
The reference oscillator settings are not affected by an instrument preset ([Preset] key
or *RST) and the "Save/Recall" function. They are reset only by factory preset.
