Function

l Function block interconnection

l Encoder settings increments of one

l Stretch factor setting over 6 decades

3.2.31.1 Function block interconnection

The function block is connected directly after the digital frequency input DFIN.

STOP!

The DFIN code C0425 must be set to selection 6 to evaluate the encoder signals correctly.
