[: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 message
"RF output deactivated'.
Parameters:
<State> 0 | 1 | OFF | ON
*RST: 0
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.
[:SOURce]:ROSCillator:EXTernal:SBANdwidth <SBandwidth>
The command selects the synchronization bandwidth for an external reference signal.
Parameters:
<SBandwidth> WIDE | NARRow
NARRow
Synchronization bandwidth is approx. 1 Hz.
WIDE
Synchronization bandwidth is approx. 750 Hz.
Example:
ROSC:SOUR EXT
selects the external source.
ROSC:EXT:FREQ 5 MHz
informs the instrument that the external reference has a frequency
of 5 MHz.
ROSC:EXT:SBAN WID
selects wideband setting for synchronization bandwidth.
[:SOURce]:ROSCillator[:INTernal]:ADJust:VALue <Value>
