Making Measurements
Example 9: Adjacent Channel Power Measurement
The adjacent channel power measurement also can be performed with
NOTE
the spectrum analyzer settings that you choose. For example, if you
want to perform the ACP measurement with a specific resolution
bandwidth, or in a particular span, set the spectrum analyzer up in the
state that you want, then use
the adjacent channel power measurement without changing the
instrument state. The ACP compute function is only available when
using the analog or peak method.

a graphical display of the adjacent channel power ratio, for the
selected channel bandwidth, as a function of the channel spacing.
The ACP graph function is only available when using the analog or
peak method.
A delta marker is activated, with the reference marker at the center
frequency, and the marker spacing equal to the channel spacing.
The ACP graph lets you see how rapidly the ACP ratio changes with
channel spacing. The ACP graph is not defined for channel spacings
where the graph is drawn at the bottom graticule line. For these
points, the channel bandwidth would include frequencies beyond the
edges of the screen, where no data was taken.
