delay field
The field that
sets the
horizontal
position of the
waveform on
the screen for
the

from the
trigger point.
It is measured
in seconds,

in the Delay
field, and is
set by using
the knob or
the keypad.
deskewing
To cancel or
nullify the
effects of
differences
between two
different
internal delay
paths for a
signal.
Deskewing is
normally done
by routing a
single test
signal to the
inputs of two
different
modules, then
adjusting the
delay path to
one of the
modules so
that both
modules
recognize the
signal at the
same state at
the same
time.
don't care
Signifies that
the state of
the signal,
high or low, is
not relevant
to the
measurement.
That is, the
analyzer will
