2.3.3 Measuring the Power Density of Wide Band Digital Modulation Signal

2-80

Figure 2-89 Displaying the Measuring Window

Measuring the power density

15. Press POWER, Channel Power, 1, 0 and Hz(ENTR).

The power density of 1 MHz band is measured and displayed.
An averaging count of 10 is set.
The power density of 1 MHz band and the averaging count are displayed in the
result area (See Figure 2-90).
