• for Node A Input Configuration:
• Bit 1 - an event at slot 1 can trigger Node A. As trig1:outp stf is set,
Node A can be triggered if a sweep step finishes for a tunable laser module
installed in slot 1.
The following explanation explains the sequence with which actions are
triggered.
1 sour2:wav:swe star arms the sweep for for the tunable laser module in
slot 2. Because trig2:inp next is set, the module waits for a trigger until
it performs the first step of the sweep.
2 sour1:wav:swe star commands the tunable laser module in slot 1 to
start sweeping. Because trig1:inp ign is set, the module performs a
sweep as normal.
3 When the module in slot 1 finishes a step, because trig1:outp stf is set,
Node A is triggered.
4 Node A triggers all modules because the Output Matrix Configuration is set to
zero. Node A triggers the tunable laser module in slot 2 to perform a sweep step
because trig2:inp next is set.
5 The sequence starts again at step 3 and continues until the sweep ends.
