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.

The analyzer incorporates Windows XP as the operating system. Some
combinations of internal measurement applications and external applications
may cause deterioration in the basic performance or conflicts between these
applications.
It is not recommended that you install other applications, including Microsoft

PAUSEThe user has temporarily stopped acquisition/measurement cycling.
The instrument acquires and measures without waiting for a trigger event.
The acquired data is stored in the data memory from address zero in order of
acquisition. When you set a trigger condition, the acquired data is stored in the

post-trigger region. (See Figure 22.)

Pollution Degree
Description
Pollution Degree
A measure of the contaminates that could occur in the environment around
and within a product. Typically the internal e nvironment inside a product is
considered to be the same as the external. Products should be used only in the
environment for which they are rated.
Pollution Degree 1. No pollution or only dry, nonconductive pollution occurs.
Products in this category are generally encapsulated, hermetically sealed, or
located in clean rooms.
Pollution Degree 2. Normally only dry, nonconductive pollution occurs.
Occasionally a temporary conductivity that is caused by condensation must
be expected. This location is a typical office/home environment. Temporary
condensation occurs only when the product is out of service.
Pollution Degree 3. Conductive pollution, or dry, nonconductive pollution
that becomes conductive due to condensation. These are sheltered locations
where neither temperature nor humidity is controlled. The area is protected
from direct sunshine, rain, or direct wind.
Pollution Degree 4. Pollution that generates persistent conductivity through
conductive dust, rain, or snow. Typical outdoor locations.
Pollution Degree 2 (as defined in IEC 61010-1). Note: Rated for indoor use only.
