7.13.13 SOURce:ROSCillator Subsystem
This subsystem contains the commands for setting the external and internal reference
frequency.
The settings of the reference oscillator are not affected by an instrument reset (*RST
on page 236). They are only reset to factory state by the factory-preset (:SYSTem:
FPReset on page 239).

[:SOURce]:ROSCillator:EXTernal:FREQuency <Frequency>
Indicates the frequency value of the externally applied reference signal (10 MHz).
Parameters:
<Frequency> 5MHZ | 10MHZ | 13MHZ | 10MHZ
*RST: 10MHZ
Example:
ROSC:SOUR EXT
Selects the external source. The reference must be input at the
REF IN connector.
ROSC:EXT:FREQ?
Response: 10 MHz external reference frequency.
Manual operation: See "External Reference Frequency" on page 128
[:SOURce]:ROSCillator:EXTernal:RFOFf[:STATe] <State>
Activates that RF output is automatically switched off, when in external source mode
no reference signal is supplied.
This setting ensures that no improper RF signal due to the missing external reference
signal is output and used for measurements.
In addition to the error message "Ext Ref missing", the instrument generates the mes-
sage "RF output deactivated'.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: --
Example:
ROSC:SOUR EXT
Selects the external source. The reference must be input at the
REF IN input.
Example:
ROSC:EXT:RFOF:STAT ON
In case of a missing external signal, no RF signal is output.
