The sweep will begin when you press on Start. The system will position
itself at the start wavelength and wait for a synchronization signal. Then,
the system will wait for a synchronization signal to go to the next step in the
sweep.
If the synchronization signal arrives before the sweep is completed, it is
kept in memory to be used on the next step. The memory keeps only one
synchronization signal in advance; if the system receives more than one
synchronization signal before the step is completed, only the first signal will
be kept.
(a) sweep start
(b) second sweep trigger
(c) trig received during the
second sweep; kept in
memory and will trigger
the third sweep
(d) trig received during the
third sweep kept in
memory and will trigger
the fourth sweep
(e) lost trig
