Width
Width
sets the absolute pulse width measured from the start of the leading edge to
the start of the trailing edge. In this format, the pulse width is independent of changes
in pulse period and delay. Pulse width is defined at the 50% amplitude level of the
pulse.
The duty cycle is the pulse width measured from the start of the leading edge to the
start of the trailing edge expressed as a percentage of the period.
Duty Cycle
value in
percents as Width/Period is shown under
Width
control. Width value can be set from
200 ns to 4 µs, adjustable in 200 ns - 500 ns - 1 µs - 2 µs - 4 µs coarse increments or
a 25 ns fine increment.
The following duty cycle limitations apply to
Positive Output
and
Negative Output
based on SRD technologies:
·
From 2.5 V to 4 V amplitude: 50% max.
·
From 4.1 V to 6 V amplitude: 20% max.
No duty cycle limitations apply to TD-based outputs.
Delay
The PicoSource pulse generators do not provide variable delay as the absolute delay
from the trigger output to the start of the leading edge of the pulse can be ignored.
The generators provide deskew between output channels for both SRD and TD
technologies.
