To measure band power

Making Simple Noise Measurements

To measure band power

1Initialize the analyzer: Press [Preset].

2Turn on averaging: Press [Average], [average on].

3Start an averaged measurement:

Press [Meas Restart].

4Turn on the band power markers:

Press [Marker Function], [band power markers], [band pwr mkr on], [band power] Press [ResBW/Window], [detector], [sample]

Press [Marker Function], [band power markers].

5Change the width of the band:

Press [band right], [MarkerEntry],

then use the knob to move the marker to the desired location. Press [band left],

then use the knob to move the marker to the desired location.

The display should similar to the one below. The grid lines have been turned off to highlight the band power markers.

Band power markers

Band power magnitude

In this example you are measuring the power of the analyzer’s noise floor within a defined band. The value displayed in the lower left corner of the display reflects the total power within the frequency band encompassed by the markers. The grid lines have been turned off to highlight the band power markers.
