Set to Default
Calls the default settings.
Remote command: 
[:SOURce]:ROSCillator:PRESet on page 639
Source
Selects the reference frequency source.
"Internal"
Uses the internal reference oscillator, either with calibrated or a user-
defined adjustment value.
"External"
Uses an external reference signal.
The frequency of the external reference signal must be set with the
parameter "External Reference Frequency".
Note: If the external reference is missing, the R&S SMA100B issues
a warning message and indicates the icon 
 (external reference
missing).
See "External Reference Frequency" on page 273.
Remote command: 
[:SOURce]:ROSCillator:SOURce on page 639
Show Connector
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
Deactivate RF Output (if external reference is missing)
Turns off the RF output when the external reference signal is selected, but no signal is
supplied.
This function prevents that no improper RF signal due to the missing external refer-
ence signal is used for measurements. A message indicates that the RF output is
deactivated.
Remote command: 
[:SOURce]:ROSCillator:EXTernal:RFOFf[:STATe] on page 640
External Reference Frequency
Sets the frequency of the external reference signal.
"Variable"
Option: R&S SMAB-K704
The external reference signal has an arbitrary frequency, within the
permissible range from 1 MHz to 100 MHz.
Set the output frequency with the parameters in the Reference Output
dialog.
