Figure 4.8: Sequence Options of the Square Sequence(s) Mode.
The Square Sequence(s) mode allows the creation of a square TTL pulse sequence. The Sequence(s) Options of this
mode are shown in Figure 4.8a and are explained below.
1. The Starting Delay defines the time between the activation of the pulse sequence and the beginning of the first
light illumination.
2. The Frequency sets the frequency (in Hz), which is the number of pulses per second. The frequency can also be
changed to the Period . For example, a light illumination at 10 Hz (frequency) will output one pulse every 100
ms (period), whereas a light illumination at 0.5 Hz (frequency) will output one pulse every 2 seconds (period).
3. The Time ON defines the length of a single pulse. This time can also be converted to a Duty Cycle , which
represents the % of the period the pulse duration corresponds to.
4. The Smoothing check box allows to change the pulse slope in square pulse sequences. The Edit Edges button
opens the Smoothing Edge(s) window. An overview of the window opened by Edit Edges will be done in the
next subsection.
5. The Pulse(s) per sequence set the number of pulses per sequence. If it is set to 0, the number of pulses will be
infinite.
6. The Number of sequence(s) sets the number of times that the sequence will be repeated.
7. The Delay between sequences sets the delay between each sequence.
8. The Total Duration shows the total expected duration of the pulse sequence. Should the duration be infinite,
the box will display
∞
. If there is an error in parameter selection, this box will turn red and display what is the
error (see Figure 4.8b ).
