SRM: WHEN SAFETY COUNTS
Wideband measuring equipment gives blanket coverage
of large frequency ranges, which could range from
the broadcast band to the mobile phone band and
beyond, for example. When fitted with special probes,
such equipment can deliver results that are expressed
automatically in terms of the applicable permitted limit
values. These devices are usually easy to operate.
Selective devices such as spectrum analyzers break the
fields down into their individual frequency components,
allowing detailed analysis. They are more complex to
operate and some specialist knowledge is needed to
evaluate results.
The Selective Radiation Meter SRM-3006 from Narda
Safety Test Solutions combines the analysis features of
a spectrum analyzer with the simple application of a
wideband measuring set. It was developed specifically
to address safety concerns in electromagnetic fields. In
contrast to a “converted” spectrum analyzer, it provides
users with application-oriented operating modes for
measuring separate transmission channels and services
such as analog or digital broadcasts (TV, DVB-T, DAB),
mobile phones (GSM, UMTS, LTE) or wireless (WLAN,
WiMAX). Results are displayed as individual values in
tables and as an overall total value, expressed in units of
field strength, power density, or simply as a percentage
of the permitted limit value. You don’t need to be an
expert in spectrum analysis to use the SRM.
