Agilent Technologies N9913A User Manual page 116

The following two Channel Power levels are displayed:
 Channel Power - measures total power over the specified Integrated BW.
 Power Spectral Density – same measured power, but mathematically
How to select Channel Power
 Press Measure 1
 Then
 Then
When Channel Power is selected, the following settings are maintained from a
previous measurement: Center Frequency, Preamp ON|OFF, and RF Attenuation.
Integration Bandwidth
When Channel Power is selected, vertical posts appear on the display to mark the
current Integration Bandwidth setting. The displayed Channel Power and Power
Spectral Density values are measured and calculated over the specified
Integration Bandwidth.
By default, the displayed frequency span is automatically coupled to the
Integration Bandwidth. As you change the Integration Bandwidth, the frequency
span is adjusted so that the vertical posts appear to NOT move. However, when
you manually change the frequency span, the Integration Bandwidth is no longer
coupled to the frequency span.
When a Radio Standard is selected, the appropriate Integration Bandwidth is set
automatically. Learn more about Radio Standards on page 84.
To change Integration Bandwidth:
 Press Meas Setup 4
 Then
 Enter a value between 100 Hz and 3 GHz using the numeric keypad, ▲|▼
 Press Enter
Other Channel Power Settings
All relevant FieldFox settings are made automatically to ensure the highest
accuracy, such as ResBW, VideoBW, and sweep (SwpAcquisition) speed. These,
and all other SA Mode settings, can be changed manually in a Channel Power
measurement.
