Complex Sequence(s)
If needed, it is possible to define a complex sequence to trigger the light source in the
Complex Sequence(s) Options
(Fig.
Figure 4.10:
Complex Sequences Window
1. The
Starting Delay
sets the delay (in hh:mm:ss:zzz format) before the first light illumination.
2. The
Current
sets the maximum current (in mA) for the given sequence.
3. The
Nb. Seq.
sets the number of times that the sequence will be repeated, with a minimum of 1.
4. The
Delay between sequences
sets the delay (in hh:mm:ss:zzz format) between each sequence if
Nb.Seq.
is
greater than 1.
5. The
Pulses per Seq.
sets the number of pulses per sequence, with a minimum of 1.
6. The
Frequency
/
Period
sets the frequency (in Hz) or period (in ms) for the pulse sequence. These two values are
linked, and when one is changed the other will adjust automatically. 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).
7. The
Time ON
/
Duty Cycle
sets the time (in ms) or the duty cycle (in %) for each pulse. These two values are linked,
and when one is changed the other will adjust automatically. The
Time ON
must be lower than
Period
+0.005 ms,
while the
Duty cycle
must be below 100 %.
8. The
Types of pulses
sets the pulse type. Pulses can be
Square
, triangular (
Triangle
),
Ramp up
,
Ramp down
or
Delay
. The
Delay
pulse type is used to create a delay between different sequence.
9. The
Sequence controls
allow the addition (
+
) or removal (
-
) of sequences to the spreadsheet.
10. The
Total Duration
displays the total time of the experiment. The different values can be
Inf
for infinite, a valid
time value or
Err
if the
Time ON
value is greater than the
Period
.
