Figure 3.2.35: Power Distribution Graph
Power Distribution Graph
See Figure 3.2.35 . The exciter measures the relative power levels of the signal and determines the
probability of exceeding a given power level, relative to the average power. The data is plotted in the
Power Distribution Graph
as a CCDF (complementary cumulative distribution function). The x-axis
displays the relative power level in dB, with the reference representing the average power. The y-axis
displays the probability of exceeding that power level. This graph can be used to assess the distribution
of a given signal, and provides an indication of the amount of peak power capability required.
Click on the panel to display a cursor in the approximate area on the trace. The cursor position (power
level and probability) is noted in the upper, right-hand corner of the panel. Click in other areas of the
instrument panel to provide a coarse adjustment of the cursor position.
Use the left and right buttons to make fine adjustments to the cursor position.
Use the up or down button to maximize (if it was minimized) or minimize (if it was maximized) the
panel size.
