Changing general
analyzer parameters
For the channel power, ACPR and OBW measurements within the spec-
trum
analysis mode, the general settings such as center frequency, span,
resolution bandwidth, can be changed as usual. A single-button
approach to adjusting span, resolution bandwidth, video bandwidth,
detector and trace mode is described below.
1 From the Spectrum Analysis main menu, select
Measure.
2Press
Adjust Settings.
Resolution bandwidth and video bandwidth are automatically set to
optimum values (automatic mode). The trace detector is set to
sample and the trace mode is set to actual.
If channel power measurements are selected, the span is set to
120% of the selected channel width. For ACPR measurements, the
span is adjusted to 1.2 channel width + 2 channel spacing. The
OBW span is three times the channel width.
