The new generation of NRA RX 19” remote analysers from Narda Safety Test Solutions automatically detect and take into account the calibration data of Narda’s own brand of antennas and RF cables, so monitoring and safety measurements in electromagnetic (EM) fields can be made without the need for conversion calculations.
Users can make use of any directional antenna in the company’s range. The compass data from the antennas can be retrieved by the instrument to get the direction information. It is also possible to use e.g. the three-axis antennas from the Narda Safety range in the same way, so that the electromagnetic field can be monitored isotropically (non-directionally) – this allows direct measurements for human and environmental safety to be made.
Users can also generate the appropriate data sets with calibration and correction values for antennas and cables from other manufacturers, using the NRA-Tools PC software.
Depending on the model, these remote analysers cover a frequency range from 9 kHz to 6 GHz with resolution bandwidths from 10 Hz up to 32 MHz. They can be integrated into practically any test and monitoring environment thanks to their Ethernet interface (100BASE-TX) and plain text remote control commands in ASCII. Rapid transmission of large quantities of data is possible in binary format.
Application-oriented operating modes include spectrum analysis, parallel power measurement in different channels, measurement of RMS and peak levels, and capture of a signal’s time characteristic. Power consumption of less than 20 VA means that the units operate silently, without the need for forced ventilation. At 1U in height and weighing less than 5 kg, they are ideal for use in mobile systems or in confined spaces.
