Span setting up to 10 MHz.

 

 

Make sure the Channel Power measurement is selected under the MEASURE menu. The Meas Setup key accesses the menu which allows you to modify the average number and average mode for this measurement.

The following parameters can be changed according to your measurement requirement:

Integ BW - Allows you to specify the integration bandwidth in which the power is measured. The range is 1.000 kHz to 10.0000 MHz with 1 Hz resolution. Since Integ BW is coupled to Chan Power Span in the factory default condition, if you change the integration bandwidth setting, the channel power span setting changes by a proportional amount, 1.626 times the integration bandwidth, until a limit value is reached.
