Parameters:
INTernal|EXTernal | COUPlec|ECOuplec
INTernal
The signal of the internal local oscilltor is used. This mode
corresponds to a normal operation.
EXTernal
An external signal is used for path A.
In case of a two-path instrument, the internal local oscillator signal
is used for path B.
Note: Selection of LO Coupling "External" mode, disables all
parameters in the "Frequency/Phase/Ref Osc" dialog of the
selected path.
COUPlec
(the parameter is enabled for two-path instruments only)
The LO signal of path A (master) is coupled to path B.
Note:
Selection of LO Coupling "Coupled A->B" mode, disables all
parameters of the SOURce:FREQuency Subsystem of the other
path.
The frequency of path A will be set to the smaller of both
frequencies of path A and B.
ECOuplec
(the parameter is enabled for two-path instruments only)
An external signal is input on the LO IN connector and used for
the coupled paths A and B.
Note: Selection of LO Coupling "External Coupled A->B" mode,
disables all parameters of the SOURce:FREQuency Subsystem
of both paths.
