External Tuning Active
For "Source > Internal", activates the EFC (external frequency control).
EFC is a function that transforms an external tuning voltage into frequency shift, where
the value range of the resulting frequency is a technical characteristic listed in the data
sheet.
See the data sheet also for information on the sensitivity, input voltage range, impe-
dance and maximum bandwidth for external tuning signal.

External Tuning Slope
Sets the sensitivity of the external tuning voltage.

9.3 Reference output settings
Access:
1. Select "Frequency" > "Reference Frequency".
2. Select "Reference Output".
In the "Reference Output" tab, you can set the reference frequency value at the
output connectors.
As a result of parameter dependencies, "Preset This Parameter" sometimes does
not affect output dialogs.
The remote commands required to define these settings are described in Chap-
ter 14.16.12, "SOURce:ROSCillator subsystem", on page 691.
Settings:
Reference Output/1 GHz Reference Output............................................................... 298

Reference Output/1 GHz Reference Output
Selects frequency reference output signal for downstream instruments.
