Description
To view the detailed region between the two line markers and categorize
the waveform according to events based on upper and lower threshold.
Amount of current consumed according to the different events illustrated
in a bar chart.
Graph of time taken when a signal is at or above a given power level. A plot
of relative power levels versus probability to explain peak-to-average
ratios. You can maneuver the respective X and Y value markers.
Y axis: Time in percentage
X axis: Current in Log scale
In the example below, the line marker will display the respective X and Y
values being X = 6 m and Y=2. This result is interpreted as 2% of the
accumulated time domain current will be higher than 6 mA.
Calculate occupied time in percentage and illustrate in a pie chart
according to the color of each label.
