Figure 6-4: Timing Diagram: Mode 0, Triggering with Strobe Delay
• T
cs
(Clear Start Latency)
This 2

s interval defines the delay from the receipt of trigger to the start of the
Clear Pulse to the sensor.
This is the reaction time of the optoisolator.
• T
sd
(Strobe Delay)
This interval defines an optional, user-adjustable delay from the start of the
Clear Pulse to the issue of the Strobe Pulse.
By default the strobe pulse begins at the time the Clear Pulse ends (i.e., T
sd
= 0).
The delay is under software control and is programmable from 0 to 1 second in
100 ns increments.
• T
sw
(Strobe Width)
The duration of the Strobe Width equals the time of the Clear Pulse (T
cp
) plus
the Integration Time (T
int
) minus any optional Strobe Delay (T
sd
).
By default the Strobe Pulse begins at the time the Clear Pulse is sent to the
sensor. The start of the Strobe Pulse may be delayed by a user-adjustable
setting in the software.
