Parameters 227
28.11 Ext1 frequency ref1 Selects Ext1 frequency reference source 1.
Two signal sources can be defined by this parameter and
28.12 Ext1 frequency ref2. A mathematical function (28.13
Ext1 frequency function) applied to the two signals creates an
Ext1 reference (A in the figure below).
A digital source selected by 19.11 Ext1/Ext2 selection can be
used to switch between Ext1 reference and the
corresponding Ext2 reference defined by parameters 28.15
Ext2 frequency ref1, 28.16 Ext2 frequency ref2 and 28.17
Ext2 frequency function (B in the figure below).
