Settings:
Adjustment Active ....................................................................................................... 305
Adjustment Value ........................................................................................................ 305
Adjustment Active
Selects the adjustment mode.
"OFF" Uses the calibrated internal reference frequency.
"ON" Allows you to apply a deviation to the internal reference frequency,
according to your requirements.
Enter the value in the
Adjustment Value field.
Remote command:
[:SOURce]:ROSCillator[:INTernal]:ADJust[:STATe]
on page 881
Adjustment Value
Sets a user-defined adjustment value for the internal reference frequency. This value
takes effect when it is activated with
Adjustment Active .
●
"0" represents the calibrated state.
●
The setting range depends on the reference oscillator type and its factory calibra-
tion value.
Note:
The setting is not affected by an instrument preset ([Preset] key or
*RST
) and the
"Save/Recall" function. It is reset only by factory preset.

6.9 Local Oscillator Coupling
The "LO Coupling" function allows a distribution of the local oscillator signal in a way
that multiple RF signals can be derived from the same LO signal. Derivation from the
same LO signal is mandatory for minimizing the phase fluctuations between these RF
signals.
The R&S SMBV100B uses either the internal oscillator frequency for the LO signal,
that is the output signal of the internal synthesizer, or an external frequency source.
Connectors
●
The internal LO signal is output at the LO Out connector.
●
An external signal is fed in at the LO In connector.
