"External
(BNC)"
The analyzer synchronizes to an external reference clock via its rear
panel Reference In BNC connector.
The external reference signal has to meet the specifications of the
data sheet; its frequency must be specified in the Ext Frequency field.
The synchronized internal 10 MHz reference clock is also made avail-
able at the Reference Out BNC connector. In addition, a synchron-
ized 100 MHz reference signal can be provided at the Reference
In/Out SMA connector (see "Reference I/O (SMA) > Out"
on page 887). Use these signals to synchronize other devices.
"External
(SMA)"
The analyzer synchronizes to an external 100 MHz or 1 GHz refer-
ence clock via its rear panel Reference In/Out SMA connector.
No reference signal is provided to the Reference Out BNC connector.
Remote command:
[SENSe<Ch>:]ROSCillator[:SOURce]
Reference Out (BNC)
The outgoing reference signal the analyzer provides at its rear panel Reference Out
BNC connector depends on the selected reference clock source:
Reference Clock Source "Reference Out (BNC)"
"Internal" 10 MHz
"External (BNC)" 10 MHz
"External (SMA)" Off
Ext Frequency
Specifies the frequency of the external reference clock signal at Reference In.
Remote command:
[SENSe:]ROSCillator:EXTernal:FREQuency
Reference I/O (SMA) > Out
Defines whether a 100 MHz reference clock signal is output to the Reference In/Out
SMA connector.
Ineffective and disabled if this connector is used as reference clock source.
Remote command:
[SENSe:]ROSCillator:SMA:OUTPut
Reference I/O (SMA) > In
Specifies the frequency of the incoming reference clock signal at the Reference In/Out
SMA connector (100 MHz or 1 GHz).
Effective and enabled if and only if the Reference In/Out SMA connector is used as
reference clock source.
Remote command:
[SENSe:]ROSCillator:SMA:INPut
