trig:conf:ext #H2,#H0,#H0
trig2:outp dis
trig2:inp next
sour2:wav:swe star
trig1:outp stf
trig1:inp ign
sour1:wav:swe star
trig:conf:ext #H2,#H0,#H0 is described by Figure 4-1
and sets one bit:
• 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.
