R&S ZNB/ZNBT
Remote command:
SYSTem:PASSword[:CENable]
Service Function
Identifier of the service function in "dotted textual" (example: sw.common.mem-
ory_usage) or "dotted decimal" (example: 0.1.18.0) representation.
Remote command:
DIAGnostic:SERVice:SFUNction
5.18.2 Freq. Ref. tab
Selects a reference signal for synchronization between the R&S ZNB/ZNBT and exter-
nal devices. A common reference frequency is advisable to ensure frequency accuracy
and frequency stability in the test setup.
State
Indicates the state of the internal phase locked loop: If the frequencies are properly
synchronized, the state is "locked".
Remote command:
n/a
Internal/External
Selects the internal or an external reference clock signal for synchronization.
●
Internal: The analyzer synchronizes to its internal 10 MHz reference clock.
Use the Ref Out connector at the rear of the instrument to synchronize other devi-
ces (e.g. signal generators or a second R&S ZNB/ZNBT network analyzer).
●
External: The analyzer synchronizes to an external reference clock via the Ref In
connector at the rear of the instrument.
The external reference signal has to meet the specifications of the data sheet; its
frequency must be specified in the "Ext Frequency" field. The internal reference
signal is synchronized to the external signal. The external signal is also looped to
Ref Out, so that it can be reused to synchronize other devices.
Remote command:
[SENSe<Ch>:]ROSCillator[:SOURce]
Ext Frequency
Specifies the frequency of the external reference clock signal at Ref In.
