Key Reference
Meas
Meas Type Specifies the reference for the measurement, either To t al Pw r
Ref or PSD Ref. Relative values are displayed referenced to
either the total power (Tot a 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 Pwr Ref
(PSD Ref)
Auto Man
Sets the adjacent channel power reference to automatic or
manual when Meas Type is set to To tal P wr 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 is
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 limits testing 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 no results will be displayed.
