6. The Repeatable sequence checkbox, when selected, allows a sequence to be repeated. Not all modes and
trigger types can be repeated. Please refer to the Figure 4.7 to know the repeatable sequence combinations.
7. The TTL Output checkbox, when selected, allows the output BNC channel to be used as a TTL generator. The
monitoring signal will provide a TTL signal instead of an analog voltage output proportional to the LED current.
The output will send out a 5 V signal whenever the input current is >0 mA. This can be used even if a light
source is not connected.
8. The Sequence Visualisation shows a graphical representation of the behavior of the selected Trigger Option
Type, Mode and Repeatability.

4.1.3 Sequence(s) Options Section
Continuous Wave
The Continuous Wave mode is used to set the Light Source to a chosen intensity without variations during experi-
ments.
External TTL
The External TTL mode is used to drive the Light Source to a chosen intensity when the External TTL signal is high.
When the External TTL signal is low, the Light Source is turned OFF.
External analog
The External Analog mode is used to drive the Light Source in function of the analog voltage used as input. The input
voltage may varies between 0 V and 5 V and the intensity will follow the variations between 0 mA and the maximum
current.
