d) The
Square sequences
mode has the light source follow a square pulse sequence.
i. The
Starting Delay
(Fig.
) sets the delay (in hh:mm:ss:zzz format) before the first pulse.
ii. The
Frequency/Period
(Fig.
) sets the frequency (in Hz) or period (in ms) for the pulse sequence.
For example, a signal at 10 Hz (frequency) will output one pulse every 100 ms (period), whereas a pulse
sequence at 0.5 Hz (frequency) will output one pulse every 2000 ms (period).
iii. The
Time ON/Duty Cycle
(Fig.
) sets the time (in ms) or the duty cycle (in %) for each pulse. The
Time
ON
must be lower than (1/fre0.005 ms, while the
Duty cycle
must be below 100 %. These
squares will appear red should an impossible
Frequency
/
time ON
be selected. Should the
Smoothing
option be selected, this feature becomes inaccessible.
