Channel Measurements
Figure 9-9 Channel Power Measurement
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
normalized to a 1 Hz bandwidth using the same algorithm as Noise Marker.
Learn more about the Noise Marker in “Noise Marker” on page 191.
How to select Channel Power
—Press Measure 1
—Then Channel Measurements
—Then Channel Power
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.
