Set to Default
Calls the default settings.
Remote command:
[:SOURce]:ROSCillator:PRESet on page 502
Source
Selects the reference frequency source.
"Internal"
Uses the internal reference oscillator, either with calibrated or a user-
defined Adjustment Value.
Note: The internal reference frequency automatically uses Synchroni-
zation Bandwidth > Narrow. Thus, if you preset this parameter, or set
the reference source from "External" to "Internal" manually, the
R&S SMB100B sets the bandwidth to "Narrow".
"External"
Uses an external reference signal.
Note: If the external reference is missing, the R&S SMB100B issues
a warning message and indicates the icon (external reference
missing).
To set the frequency of the external reference, see "External Refer-
ence Frequency" on page 186.
Remote command:
[:SOURce]:ROSCillator:SOURce on page 502
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 502
External Reference Frequency
Selects the frequency of the external reference signal.
Set the reference output frequency with the parameters in the Reference output set-
tings dialog.
