[:SOURce]:ROSCillator:EXTernal:FREQuency <Frequency>
Selects the external reference frequency.
Parameters:
<Frequency> 5MHZ | 10MHZ | 13MHZ
*RST:
10MHZ
Example: ROSC:SOUR EXT
selects the external source. The reference must be input at the
REF IN connector.
ROSC:EXT:FREQ 5MHz
selects 5 MHz external reference frequency.
Manual operation: See "External Reference Frequency" on page 212
[: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.
Manual operation: See "Deactivate RF Output (if external reference is missing)"
on page 211
[:SOURce]:ROSCillator:EXTernal:SBANdwidth <SBandwidth>
Sets the synchronization bandwidth for an external reference signal.
Parameters:
<SBandwidth> WIDE | NARRow
NARRow
The synchronization bandwidth is approx. 1 Hz.
WIDE
The synchronization bandwidth is approx. 750 Hz.
