value.
don't care For terms, a "don't care"
means that the state of the signal
(high or low) is not relevant to the
measurement. The analyzer ignores
the state of this signal when
determining whether a match occurs
on an input label. "Don't care" signals
are still sampled and their values can
be displayed with the rest of the data.
Don't cares are represented by the X
character in numeric values and the
dot (.) in timing edge specifications.
dot (.) See edge terms, glitch,
labels, and don't care.
double-click When using a mouse
as the pointing device, to double-click
an item, position the cursor over the
item, and then quickly press and
release the left mouse button twice.
drag and drop Using a Mouse:
Position the cursor over the item, and
then press and hold the left mouse
button. While holding the left mouse
button down, move the mouse to
drag the item to a new location. When
the item is positioned where you
want it, release the mouse button.
Using the Touchscreen:
Position your finger over the item,
then press and hold finger to the
screen. While holding the finger
down, slide the finger along the
screen dragging the item to a new
location. When the item is positioned
where you want it, release your
finger.
edge mode In an oscilloscope, this
is the trigger mode that causes a
trigger based on a single channel
edge, either rising or falling.
edge terms Logic analyzer trigger
resources that allow detection of
transitions on a signal. An edge term
can be set to detect a rising edge,
falling edge, or either edge. Some
logic analyzers can also detect no
edge or a glitch on an input signal.
Edges are specified by selecting
arrows. The dot (.) ignores the bit.
The asterisk (*) specifies a glitch on
the bit.
emulation module A module
within the logic analysis system
mainframe that provides an
emulation connection to the debug
port of a microprocessor. An E5901A
emulation module is used with a
target interface module (TIM) or an
analysis probe. An E5901B emulation
module is used with an E5900A
emulation probe.
