7. Index Pulse Divider (Marker Pulse Z)
7.1. Unchanged index pulse (bypass)
When you like to just bypass the index pulse from the input to the output (without any changes of
frequency, position and pulse width), please use the following DIL switch settings:
DIL3
DIL2

7.2. Modifications of the index pulse
The programmable index divider allows modifications of the pulse distance, the pulse width and
the pulse position.
As a precondition for use of the subsequent functions,
the input index pulse needs to have a
minimum width of one fourth of the period and a
maximum width of one half of the period of the
input frequency
Switch DIL3 allows setting of the division rate between input and output.
Positions 5 and 6 of switch DIL2 allow modification of width and position of the output pulse.
