In the "Freq " and "Lev" fields of the status bar, the R&S SMW shows the results of the
following correlations:
The level displayed in the status bar includes "Amplitude", "Offset" and "Digital Attenu-
ation".
"Offset" represents a level value that impacts the RF signal outside the R&S SMW. In
contrast, the "Digital attenuation" directly affects the level value at the RF output.
Further settings that affect the level at the RF output, like user correction, are indicated
by an icon in the status bar.
7.4 Reference Oscillator
The R&S SMW is equipped with an internal reference oscillator that generates a refer-
ence frequency of 10 MHz. It is used as internal reference source for the synthesizer
and the local oscillator. Alternatively, you can apply an external reference signal even
with a frequency different than 10 MHz.
Regardless of the used reference source (internal or external), the R&S SMW always
provides the configured reference frequency at the output. You can use it, for example
to synchronize several interconnected instruments.
The following examples briefly explain the possible test setups and the settings to be
considered.
