ELATIONSHIP BETWEEN TRIGGER CONDITIONS
Relationships between trigger conditions on edges and trigger conditions on logic levels can be set using the
Trigger condition drop ‐ down field. The following options are available:
•
Edge OR Level ‐ A trigger condition occurs when one between an edge condition or a logic level condition
is detected.
•
Edge AND Level ‐ A trigger condition occurs when an edge condition and a logic level condition are
simultaneously satisfied.
•
Edge BEFORE Level ‐ A trigger condition occurs when an edge condition is detected at least once before
one is detected on logic levels.
•
Edge AFTER Level ‐ A trigger condition occurs when an edge condition is detected at least once after one
is detected on logic levels.
•
ALWAYS ‐ A trigger condition occurs automatically when data acquisition starts. Any setting on edges or
on logic levels is ignored.
•
NEVER ‐ Trigger is inhibited. Any setting on edges or on logic levels is ignored. A trigger event, however,
can be activated manually during data acquisition.
Pattern Settings - The Clock Generator Tab
Use the Clock Generator to generate a clock signal with a frequency up to 125 MHz.
•
The clock is created on Ch15.
•
It is possible to combine the clock with the Extended Trigger In vector using the strobe function. The
following options are available: NOP , OR , AND , XOR , NOT , NOR , NAND , and XNOR .
•
The Clock generator provides a synchronized signal to the Sequencer Module to generate vectors
synchronized with the output clock.
