9.3.4.6 Measuring the Power in a Channel (Band Power Marker)

Access: "Overview" > "Analysis" > "Marker Functions" > "Band Power" > "Band Power

Config"

or: [MKR FUNC] > "Select Marker Function" > "Band Power"

To determine the noise power in a transmission channel, you could use a noise marker

and multiply the result with the channel bandwidth. However, the results would only be

accurate for flat noise.

Band power markers allow you to measure the integrated power for a defined span

(band) around a marker (similar to ACP measurements). By default, 5 % of the current

span is used. The span is indicated by limit lines in the diagram. The results can be

displayed either as a power (dBm) or density (dBm/Hz) value and are indicated in the

marker table for each band power marker.
