Label polarity fields
The label polarity fields, which are located just after the label, are used
to assign a polarity to each label. The default polarity for all labels is
positive (+). You change the label polarity by toggling the polarity field.
When the polarity is positive, 1 is high and 0 is low. When the polarity is
negative, 1 is low and 0 is high. All data as well as bit-pattern specific
configurations used for identifying, triggering, or storing data reflect
the change of polarity. Numbers use the appropriate logical encoding,
but waveforms and edges are still shown as logic levels, either low or
high. In a timing analyzer with the data inverted, the waveform display
remains positive true.
As an example, setting the logic analyzer to trigger on 0A hex with
positive polarity is the same as setting it to trigger on F5 hex with
negative polarity. The listing would show 0A with + polarity, F5 with -
polarity. In the waveform menu, if the waveform is defined as bus the
waveform shown as symbols inverts with a change of polarity. If the
waveform is defined as individual channels or is not using symbols, it is
not affected by changing polarity.
