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.
Note: If the external reference is missing, the R&S SMW issues a
warning message and indicates the icon (external reference miss-
ing).
To set the frequency of the external reference, see "External Refer-
ence Frequency" on page 475.
Remote command:
[:SOURce]:ROSCillator:SOURce on page 1200
Show Connector
Accesses a dialog that displays the physical location of the selected connector on the
front/rear panel of the instrument.
A blinking LED on the front/rear panel indicates the selected connector, too (see Chap-
ter 12.2.2.4, "Status Indicators", on page 718).
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 1200
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.
The settings depend on the versions of the RF hardware, see Appendix: RF Hardware
Versions, on page 1289.
"10
MHz"
Selects 10 MHz for the external reference frequency signal.
"100 MHz, 1 GHz"
Option: R&S SMW-K703/-K704
Selects the external reference frequency.
