New hand-held instrument measures RF radiation from 9kHz to 6GHz

Manufactured by Narda Safety Test Solutions, the SRM-3006 selective radiation meter can be used with a variety of isotropic or single-axis probes to carry out safety investigations on sources ranging from low-frequency industrial equipment, through radar and TV broadcast transmitters, right up to the latest generation of mobile communications services.

Results are shown instantly on the 152 x 91mm colour LCD display and can be expressed either as absolute values in a choice of different units or as a percentage of a permissible limit value (e.g. ICNIRP reference levels). The weighting curves for all current safety standards are stored in the instrument for this purpose.

With a resolution bandwidth as high as 32MHz, the SRM-3006 is fully equipped to monitor wideband signals, and it also offers a video bandwidth facility to smooth the trace while retaining the original resolution in the background. Maximum, minimum and average values can be displayed simultaneously, if required.

As well as automatically logging date, time and GPS co-ordinates with each measurement, the instrument is able to record written or spoken comments. Results can easily be transferred to a PC via the instrument’s USB or RS-232 interfaces, while the bundled PC software enables the user to customise tables and measurement routines and to carry out subsequent evaluation of measurement data.

Designed for outdoor use, the SRM-3006 features a robust, splash-proof housing and operates from either Li-ion rechargeable batteries or an external AC adapter. In addition, the instrument’s high immunity to electromagnetic radiation means that it can make reliable measurements in the vicinity of strong field sources.
Both the instrument and probes are calibrated, traceable to national and international standards, ensuring that all results are reliable and reproducible.
