THE SRM AND ITS APPLICATIONS
The Selective Radiation Meter SRM is a compact, frequency-selective
measuring system for safety analysis and environmental measurements
of high-frequency electromagnetic fields. It covers broadcasting, mobile
telephony, and industrial frequencies from the lowest long-wave range
up to the latest wireless applications and evaluates the field exposure
level in accordance with international or national standards.
Where the field environment is unknown – in offices, factory buildings,
public places, or private homes – the SRM provides authorities and
measurement service providers with a rapid overview of the field
sources that are relevant to human safety.
Where the field situation is known, such as at so-called “shared sites”,
where several service providers share a common antenna site, the SRM
shows the overall field exposure level as well as the proportions due to
each service as an absolute value or as a percentage of the permitted
limit value.
Users can resolve services down to individual channel accuracy and
measure their contribution to the field emission with the SRM. It is also
possible to integrate over the entire frequency range of the service and
display the absolute result or the value relative to the permitted limit.
OPERATION AND USE
All functions and parameters can be set directly on the SRM basic unit
via menus and the numerical keypad, softkeys, or the rotary control. As
well as this, the SRM also provides facilities for saving and recalling
measurement settings (setups) and entire measurement sequences
(routines). The PC software included with the device, “SRM-3006 Tools”,
includes editable tables for antennas and cables from other
manufacturers, user-defined evaluation curves, and lists of services and
operators.
OPERATING MODES
The SRM is designed for everyday use and has operating modes
tailored to the main areas of application: Safety Evaluation, Spectrum
Analysis, Level Recorder and Scope. Details about these operating
modes and other functions are given in the Specifications.
ANTENNAS
Narda offers a broad range of three-axis and single-axis measuring
antennas for electric fields (E-fields) and magnetic fields (H-fields).
The three-axis antennas are advantageous in practice because they
give isotropic (i.e. non-directional) results automatically.
