Conventions

This manual uses the following conventions:

Front-panel button and control labels are printed in the manual in upper case
text. For example, SPAN, PEAK, PRINT. If it is part of a procedure, the
button or control label is printed in boldface. For example:

Press SPAN.

To easily find buttons on the front panel, the area name label is printed
together with the button by concatenating with a colon (:), as in MODE:
DEMOD,VIEW:SCALE,MARKERS:SELECT. For example:

Press the MODE: DEMOD key.

Menu and on-screen form titles are printed in the manual in the same case
(initial capitals) as they appear on the analyzer screen, such as Span, Source,
and Channel Power. If it is part of a procedure, the menu title is shown in
boldface

Press the Source side key.

. For example:

A list of keys, controls, and/or menu items separated by an arrow symbol (→)
indicates the order in which to perform the listed tasks. For example:

Select RBW/FFT → Filter Shape... → Gaussian.

Product Overview

The RSA3303B, RSA3308B, and RSA3408B are portable real-time spectrum
analyzers. The real-time spectrum analyzer has a vastly different architecture from
traditional
random signals with equal ease. The acquired d ata is analyzed in time, amplitude,
phase, and frequency domains correlating with time. Furthermore, DPX spectrum
processing provides an intuitive understanding of time-varying RF signals with
color-graded displays based on frequency of occurrence.
