Affordable RF Exposimeter RadMan 2LT and RadMan 2XT Radiation Monitors are warning devices for the protection of people who work in areas where increased levels of electromagnetic radiation are present. Electromagnetic Energy / Electromagnetic Fields (EME/EMF). Broadcasting, telecommunications and radar antennas are sources of strong electromagnetic fields. The device is worn on the body and warns its user in good time before the permitted limit values are exceeded.
RadMan 2LT and RadMan 2XT comply with the recommendations of ITU-T K.145 with regard to the use and properties of RF personal monitors.

Display and warning signals
The actual field exposure level is indicated in six steps from 5% to 200% by LEDs. The percentages refer to the proportion of the power density limit value specified in a safety standard. If the field exposure level exceeds 50% of the limit value, the device vibrates and emits a loud alarm tone. There is also a bright light in the top part of the RadMan 2 that can be easily seen from various angles. The light flashes red in time with the alarm signal. A second, more persistent alarm sounds when the 100% threshold is exceeded, warning the user to leave the danger area.

Standard compliance by means of shaped frequency response
The permitted limit values specified in the standards vary according to the frequency. Weighting filters in the sensors of the RadMan 2 simulate the frequency response of the standard. They ensure that the alarm thresholds are correct over the entire frequency range. Settings are not necessary. 

Minimal body effect
Personal monitors are generally worn on the person. RadMan 2 is supplied fitted with a suitable attachment and RF absorber that allows it to be fixed easily to a harness or belt. The RF absorber reduces the signal reflections caused by the body which would otherwise affect the result displayed by the monitor. If needed, the RadMan 2 can be released from the attachment with one hand in order to determine the field exposure away from the body with an isotropic directional characteristic.

Isotropic measurement of electric and magnetic ELF fields

Frequency selective FFT measuring system with high dynamic range for electric and magnetic fields from 1 Hz to 400 kHz. Sensors in all three spatial directions deliver isotropic results for selective and wideband measurements.

Uses the Weighted Peak method for standard-compliant measurement of complex signals. This method, patented by Narda, evaluates the signal by means of mathematical convolution in the time domain. The result is the direct display of the exposure as a percentage of the limit value. This makes the application particularly quick and easy to use. Weighted Peak is the basis of the limit value curves of the most important standards.

Complete, easy to use test system, consisting of a base unit and measuring antennas, for non-directional detection of fields and their sources in the frequency range from 9 kHz to 6 GHz.

Frequency selective hand held field strength measuring system for rapid and reliable safety assessments with e.g. separate recording of mobile communications channels of different providers and worst case evaluation through decoding of control signals in UMTS and LTE.

SRM-3006 has become established as the standard instrument for these tasks. It provides the user with automatic evaluations taking various human safety standards into account directly in the instrument, together with a specified overall measurement uncertainty, making error-prone and complicated calculations unnecessary.

Product Features:

• Measurements conforming to ICNIRP and national standards with results displayed directly in terms of the permitted limit value
• Evaluate now already according to the new ICNIRP limits of 2020. More information under: --> Newsticker
• Fast, reliable results using predefined measurement routines, setups, and automatic settings
• LTE and UMTS operating modes for evaluating pilot signal information and extrapolation to maximum exposure levels
• Scope mode for short term analysis of pulsed signals and long term recording of variable exposure levels
• Editable tables for automatic correlation of results with telecommunications services (e.g. broadcasting, GSM, WiMAX)
• Individual preparation of field campaigns with subsequent evaluation and handling of large quantities of measurement data
• Suitable for outdoor use: Radiation protected, robust, splash-proof, ergonomically designed; uses exchangeable rechargeable batteries; equipped with integrated GPS and voice recorder

The lab in your hand. If you need to quickly detect and reliably localize hidden, sporadic or brief interference signals on the move within the more and more tightly packed frequency bands, you need the SignalShark. This device, with its handy format, is capable of dealing with today’s complex measurement and analysis tasks reliably and quickly to the same standard as laboratory instruments.

The 40 MHz real time measurement allows gapless, reliable detection of the smallest changes in the RF spectrum with the aid of the spectrogram view. 

SignalShark can also easily detect very weak signals, thanks to its high dynamic range (HDR). The combination of high sensitivity and a wide, intermodulation-free dynamic range makes this possible. DANL (pre-amplifier off / on): - 160 dBm/Hz / -167 dBm/Hz

The continuous real time persistence view of the SignalShark shows every change in a signal with pixel accuracy. Even hidden signals can be detected with this.
100% POI signals > 3.125 μs 

The slightest “touch” on a preset trigger mask causes the SignalShark to record the corresponding signal. A scan rate of up to 40 GHz/s ensures rapid detection, even with very wide frequency bands. 

Applications
More and more devices have to share the available frequency ranges because of the rapid development in new technologies such as the Internet of Things (IoT), machine-to-machine (M2M) or car-to-car (C2C) communications and expanding 4G/5G mobile networks. Whether making a wideband measurement of an entire frequency range, detecting hidden signals, reliably capturing very short impulses or localizing interference signals, SignalShark provides comprehensive measurement solutions for the increasingly complex RF spectrum.

FieldMan the electromagnetic field meter ranging from 0 Hz to 90 GHz.

The Narda FieldMan is used to make precision measurements to establish human safety, particularly in workplace environments where high electric or magnetic field strengths are likely to occur. An essential task is to demonstrate compliance with general safety regulations, such as FCC, IEEE, ICNIRP or EMF Directive 2013/35/EU.
