Application Notes 6-14
Table 6-3. Statistical Automatic Measurements
In the Statistical mode the following five automatic measurements are displayed in the 4540 Series Text display for enabled
input channels. The Text column lists the abbreviated forms that appear on the display screen.
TEXT TERM DEFINITION
Avg
Average Power: The unweighted avg of all power samples occurring since acquisition started.
Peak
Peak Power The highest power sample occurring since acquisition was started.
Min
Minimum Power The lowest power sample occurring since acquisition was started. In logarithmic
units a reading below the clip level will display as down arrows.
Pk/Avg Pk/Avg Ratio The ratio (in dB) of the Peak Power to the Average Power.
Dyn Rng
Dynamic Range The ratio (in dB) of the Peak Power to the Minimum Power. Displays down
arrows if the minimum power is less than the clip level in log units.
The following cursor measurements display the user set position (independent variable) and measured values (dependent
variables) where each enabled channel's movable cursor intersects the channel's CCDF trace. The position or value
measurement text for each dependent variable is displayed in the color of its channel. The independent variable is white.
Note that the intersection of the movable cursors and the CCDF traces can be moved outside the visible display area. This
does not affect the measurements in any way.

TERM DEFINITION
CursPwr
Cursor Power Reference Cursor Mode - Power Ref
The reference power level in dBr set by the user to define the
measurement point on the normalized CCDF for probability in percent.
Cursor Mode - Percent
The measured power level in dBr of the normalized CCDF at the
probability in percent specified by the user.
CursPct
Cursor Percentage Cursor Mode - Power Ref
The measured probabilty in percent of the normalized CCDF at the
reference power level specified by the user.
Cursor Mode - Percent
The probabilty in percent set by the user to define the measurement
point on the normalized CCDF for power level in dBr.
