Reference Oscillator - R&S SMB100A Operating Manual

R&S SMB100A
The combined "RF Frequency / Phase ..." settings dialog contains the parameters
to configure the phase settings of the RF signal.
The remote commands required to define the settings are described in
ter 7.13.10, "SOURce:PHASe
Delta Phase
Sets the phase of the RF signal. The current phase of the signal is used as the refer-
ence. This function allows, for example, the phase of the output signal to be synchron-
ized with the phase of a signal from a second signal generator.
Remote command:
[:SOURce<hw>]:PHASe
Reset Delta Phase Display
Resets delta phase value. The set phase is adopted as the new current phase, i.e. the
delta phase value is reset to 0.
Remote command:
[:SOURce<hw>]:PHASe:REFerence

5.3.4 Reference Oscillator

The R&S SMB is equipped with an internal reference oscillator that generates a refer-
ence frequency of 10 MHz. It is used as internal reference source for the synthesizer
and the local oscillator. Alternatively, you can apply an external reference signal.
Regardless of the used reference source (internal or external), the R&S SMB always
provides the configured reference frequency at the output. You can use it, for example
to synchronize several interconnected instruments.
The settings of the reference oscillator are not affected by an instrument preset ("PRE-
SET" key).
The following examples briefly explain the possible test setups and the settings to be
considered.
