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.
Remote command:
[:SOURce]:ROSCillator:INTernal:TUNing[:STATe] on page 639
External Tuning Slope
Sets the sensitivity of the external tuning voltage.

8.4 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 13.16.12, "SOURce:ROSCillator Subsystem", on page 637.
Settings:
Reference Output/1GHz Reference Output................................................................ 275
Show Connector..........................................................................................................276
Reference Output/1GHz Reference Output
Selects the signal that is to be output as frequency reference for downstream instru-
ments.
"Off"
Disables the reference signal output.
"10 MHz/100 MHz"
Derives a signal with 10 MHz or 100 MHz frequency from the internal
reference oscillator and forwards this signal to the output.
