Fig. 3. Structure or internal logic of the delay generator
In the previous figure, we have the following blocks:
•
IN: It is the Pulse input to the equipment
•
Out A, Out B and Out C: These are the pulse outputs of the equipment
•
Pulse Counter: Counter block of the pulses that enter through IN, emits a pulse
towards the “Selector” block every time the count programmed by the user is reached
from the equipment's touch screen.
•
Selector: Block that selects between the “IN” input or the “Pulse Counter” output to
connect to the delays of the “Out B” and “Out C” outputs
•
Delay A: Block that performs the delay function for the “Out A” output, receives a
pulse directly from “IN” and a configurable “dA” time, then emits a pulse in “Out A”
with a duration or value width "Wa"
•
Delay B: Block that performs the delay function for the “Out B” output, receives a
pulse from “IN” or from “Pulse Counter” depending on the position of the “Selector”
and a configurable time “dB” then emits a pulse in "Out B" with a duration or width of
value "Wb"
•
Delay C: Block that performs the delay function for the “Out C” output, receives a
pulse from “IN” or from “Pulse Counter” depending on the position of the “Selector”
and a configurable “dC” time then emits a pulse in "Out C" with a duration or width of
value "Wc"
Note that the "Out A" output differs from "Out B" and "Out C" in that the latter can receive a
pulse from the "Pulse Counter" module or directly from "IN", depending on the position of the
"Selector" module, but "Out A" only receives pulses directly from "IN" through its "Delay A". Such
configuration of outputs allows in those applications where it is necessary to control the firing of a
flash lamp from the DG-3O1I-17 uninterruptedly, while an optical switch (Q-switch active) is
