286 Parameters
28.11 Frequency ref1
source
Selects frequency reference source 1.
Two signal sources can be defined by this parameter and
28.12 Frequency ref2 source. A digital source selected by
28.14 Frequency ref1/2 selection can be used to switch
between the two sources, or a mathematical function (28.13
Frequency ref1 function) applied to the two signals to create
the reference.
