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 provides a 10 MHz internal reference clock signal which can
be tapped off at the REF OUT connector at the rear of the instrument in order to
synchronize other devices, e.g. signal generators or a second R&S
ZNB/ZNBT net-
work analyzer.
●
External:
The external reference clock signal must be applied to the REF IN con-
nector at the rear of the instrument. The external reference signal must meet the
specifications of the data sheet; its frequency must be specified in the "Ext Fre-
quency" 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 re-used to syn-
chronize other devices.
Remote command:
[SENSe<Ch>:]ROSCillator[:SOURce]
Ext Frequency
Specifies the frequency of the external reference clock signal at REF IN.
Remote command:
[SENSe<Ch>:]ROSCillator:EXTernal:FREQuency
