One-Button Measurements 5
N9320A Spectrum Analyzer 125
Meas Type Specifies the reference for the measurement, either Tota l Pw r
Ref or PSD Ref. Relative values are displayed referenced to
either the total power (Tota l P w r R ef ) or the power spectral
density (PSD Ref) measured in the main channel.

Method
IBW RBW
Enables you to select the measurement method. The
resolution bandwidth (RBW) method is most useful for
measuring cdmaOne signals; the integration bandwidth
method (IBW) is preferred for other signals.

Tota l P w r R ef
(PSD Ref)
Auto Man
Sets the adjacent channel power reference to automatic or
manual when Meas Type is set to Tot al P w r R e f . When select
Auto, the carrier power result reflects the measured power
value in the carrier. When set to Man, the last measured
value is captured and held, or may be entered by the user.
Relative values are displayed, referenced to the total power
measured in the main channel.
when Meas Type is set to PSD Ref, pressing this key sets the
power spectral density in the carrier (main channel) that
will be used to compute the relative power spectral density
values for the offsets.When the PSD Ref state is set to Auto,
this will be set to the measured carrier power spectral
density.

Limits
On Off
Turns the testing of the limits on or off. When select On,
each offset is compared to its upper and lower offset limit.
In those cases where the power exceeds the limit, the
calculated result will be displayed in red to indicate a
failure. If there are any failures, the pass/fail indicator area
show “FAIL” in red; if there are none, it shows “PASS” in
green when using IBW method. Neither “FAIL” nor “PASS” will
be displayed when using RBW method. Any offsets that are
in the off state are not measured and their results will not
be displayed on screen.
