Because it will help to invest your money wisely. See Performing Band Power Measurements more information.Manpower requirement calculation is now a vital part of all manufacturing industry in this competitive world. RMS Sqrt (Pwr): the square root of average power between the band power markersĬ/N See carrier-to-noise ratio.: carrier-to-noise Power Density: the average power density for the band.Power: the average power between the band power marker's left and right edges Make the following band power calculations using the band-power markers: Right determines the location of the right band-power marker. Left determines the location of the left band-power marker. When the Center/Span check box is cleared, the position of the band power-markers is determined by these two settings: Span determines the width of the band-power markers. When the Center/Span check box is selected, the position of the band power markers is determined by these two settings:Ĭenter determines the center position of the band-power markers. The center remains fixed.Ĭlick Markers > Calculation. To maintain the band center but change the width, place the pointer on left or right edge of the band power marker and drag to the desired width. To move the center frequency, select the band power tool or the marker tool and click in the trace to position the band power marker center. A band power marker will be placed over the selected area.Ĭhange the position of a band power markers in the following ways: From the menu that appears, select Band Power. While left-clicking the mouse, drag over the frequency band of interest and release the mouse button. Then click in the trace where you want the band center to be.Ĭlick Markers > Calculation and select the Band Power check box.Ĭlick the select area tool and then move the mouse to a trace grid. Right-click in the trace and select Show Band Power from the menu.Ĭlick the band power tool in the tool bar. There are several ways to create a band power marker on a trace: The active marker's value is also shown above the trace grid to the right. The results of the band computation are shown in the Markers Window. The Y position of the marker shape depends on the Y-axis Trace Format selected for the trace.įor Lin Mag, Log Mag, and Log Mag (Lin) trace formats, the band power marker is shown at the Y-axis position corresponding to the mean band power, regardless of the settings of the band power type and band power calculation.įor Real, Imag, Group Delay, Wr Phs, and Un Phs the band power marker diamond is shown at the actual Y-axis position shown in the Markers Position tab.įor other trace formats, band power calculation is not available. The bottom point of the diamond shape indicates the center of the band. The two vertical lines indicate the left and right band edges. The band power marker consists of two solid vertical lines spaced equally on either side of a marker diamond. This screenshot shows band power marker on a spectrum trace (the trace grids are turned off so it is easier to see the marker): This topic includes the following information: Menu Path: Markers > Calculation > Band Powerīand-power markers provide a quick way to make several different power computations.
