Figure 11-6. Sample Program : Occupied Power Bandwidth Calculation (2/2)
Lines 40 to 80 set the measurement coecient, frequency span, resolution bandwidth, number
of measurement points, and averaging factor to typical values.
Lines 390 to 430 search from the left for the point where the power is 0.5 % compared to the
total power. Lines 440 to 480 do the same search from the right.
Lines 490 to 540 display the marker and 1 marker on the 0.5 % power point and read out the
spacing of the markers.
Lines 600 to 660 (subprogram ) perform a summation of the power at the measurement
points. This summation is done in the area of the center frequency ( ) and the frequency
span ( ). The same equation (11-2) is used in the \Adjacent Channel Power Calculation"
example.
