Time Alignment

A further advantage of the DSO26 over conventional products is the provision of an
independently adjustable delay section for each output. This allows the true arrival time
from multiple drivers to precisely aligned rather than relying on the compromise 'phase
adjust' approach. Delay time is adjustable in 2.6µS steps (1mm).
Please see page 20 for details of how to adjust the delay times.
To convert from units of time (i.e. milliseconds) to units of distance use the following
formula:
=
1 ms 343 mm
(1.126ft) @ 20°C (68° F)
To calculate time delay for a known distance, use:
L
=
T
delay
+ + °
20, 06 273 C
where:
L = Distance in meters
°C is the temperature in °C.
To simplify this equation at 20°C:
T = L [meters] x 2.192
delay
T = L [feet] x 0.955
delay
