1.7 Anisotropy 1) The IEEE 1309 [3] defined the anisotropy (A) as the maximum deviation from the geometric mean of the maximum response and minimum response when the probe is rotated around the ortho-axis (e.g. "virtual handle") as shown in the example in figure below. ...
A good evaluation of the anisotropy of a field probe should be carried out in a place where all of the following conditions are satisfied: Far Field Plane wave Uniform field Since the calibration systems are not infinite, these conditions can be approximated but never reached, and so the evaluation of anisotropy for our probes shows results worse than the reality.

When asked for, reboot your system to complete installation EHP50-TS software is now installed in your PC, you can remove it, if needed, simply running the “Uninstall EHP50-TS” application (see cap.8). EHP-TS software...
Page 29
The EHP50-TS section includes three different applications: Dongle Utility: allows to enable the function ordered such Options using the 40 Digit Activation Code received from NARDA Italy. EHP50 – Stand Alone Mode: main task of this program is to set up EHP- 50G for standalone mode.
Page 30
This chapter describes controls and functions provided by the EHP50-TS 4.2 EHP50-TS application for time domain and spectrum analysis, included in EHP-TS Application software package. To install EHP-50G, connect the supplied fiber optic to the OPTIC LINK connector taking care that the spigot matches the housing. Connect the other end of the fiber optic to the OPTIC LINK connector of the USB-OC or 8053-OC.

Function: measurements are displayed in different acquisition modes: Spectrum: Frequency Domain sweeps are shown;...
4.4 Span section EHP-50G includes an FFT analyzer to show frequency spectrum of measured field. The span section includes the following: Span: select one of the 8 available spans, keeping in mind that beside the EHP-50G minimum operating frequency of 1 Hz, the minimum start frequency of each Span is 1,2% of Span.
Fig.4-3 Zoom window Also choosing the best scale range 120 dB or 140 dB can be helpful to better distinguish signals and disturbances. Sweep: the two radio buttons in this box allow the user to select the Linear or Logarithmic frequency scale. Logarithmic scale is used to emphathise and clearly display low frequencies even thow high ones are included in the graph.
Page 35
Standard section allows the user to select standard ICNIRP, IEEE, BGV 4.5 Standard and EC limits, already included by the software installation, as well as user’s limits which can be created through the “Make Limit” function provided by this section. Safety Standard: This section can be used to load a default standard limit saved into the memory at the factory.
Page 36
Type frequency and field strength for each point of the required limit and click save to save it under the program directory. The limit file will be created as a linear interpolation between specified points. When the ICNIRP or IEEE limit is selected, the software automatically calculates the corresponding total integration of the measured signals, and compares the result with the threshold set by the standard, considering whether it is or is not exceeded.
Even if EHP-50G takes measurement over the entire selected span, shown 4.6 Data section results are related to the displayed spectrum only, allowing thus detailed evaluation of user defineable frequency range through the zoom function. Fig.4-4 Data section The gray band on the left side of the graph highlights signals below the minimum start frequency (1,2 % of Span) which are affected by residual 0 Hz peak.
Page 38
Four additional frames, Acquisition, Marker, Save and Waterfall, are included in the Data section: Acquisition: spectrum is displayed in different acquisition modes. Here is the choice between instantaneous reading and Root Mean Squared over a certain period, which is set in the proper box. A Max Hold function is also available.
Page 39
It is also possible to insert a comment. The user can select the path where the files will be stored. The saved files will be structured as following: Under the selected folder (EHP50-TS in the example) a folder will be created and called like the current year (ex.
Page 40
Auto save text extract example Round frequency: when this label is ticked, the frequency indication of the Marker is corrected to the closest round value, thus avoiding approximation errors. Waterfall: press Start Waterfall to run the function, or Open Waterfall to load previously saved measurements.
In addition to the spectrum view, another representation has been 4.6.1 Waterfall introduced in the software, commonly called Waterfall. The advantage of this view is that the disturbances are shown in a tridimensional plot. Two dimensions are, as usual, frequency and level, and the third is the time.
When entering the Open Waterfall function a screen similar to the following appears: Fig.4-6 Waterfall Main Window Like during the scan, on the left is the spectrogram of the measurements. The column in the middle, called Events Horizon, reports the Marker with its frequency and level and many parameters of the measurement setup and of the probe used.
Fig.4-7 Waterfall - Graph 3D In the Graph 3D, one axis (blue) represents Frequency, another the Level (green) and the third the Time (red). So the Frequency can be on the horizontal axis, the Level on the vertical axis and the Time in depth. For this mode, another box, called Movement, will appear.
Page 44
Another option of the Graph 3D, the Time plot, is available when the Marker is active. Tick the Time label to enter this view. A new window pops up and the plot represents the level at the marker frequency versus time. The horizontal axis of the grid is the time and the vertical axis is the field level.
Page 45
The subsequent spectra are automatically recorded and saved in a single 4.6.1.1 Data recording file *.WF5 localized in the folder Waterfall in the program root, inclusive of all the analyzer settings. The stored files can be recalled when in Data mode or at startup entering the Open Waterfall window.

4.8 ICNIRP The International Commission on Non-Ionizing Radiation Protection establishes guidelines for limiting EMF exposure that could affect human health. Standard section allows the user to select standard ICNIRP limits, already included by the software installation. When the ICNIRP limit is selected, the software automatically calculates the corresponding total integration of the measured signals, and compares the result with the threshold set by the standard, considering whether it is or is not exceeded.
Page 48
In the screenshot above it is depicted an example how the software shows the calculation of the ICNIRP value for the Electric Field measurement. In the screenshot above it is depicted an example how the software shows the calculation of the ICNIRP value for the Magnetic Field measurement. The limit cannot be activated when using Dual Mode.

4.9 IEEE One of the purposes of the Institute of Electrical and Electronic Engineers, Inc. ("IEEE") is to establish exposure standards. Standard section allows the user to select standard IEEE limits, already included by the software installation. When the IEEE limit is selected, the software automatically calculates the corresponding total integration of the measured signals, and compares the result with the threshold set by the standard, considering whether it is or is not exceeded.

4.10.2 EHP50-TS Settings The Standard section allows the user to select one of the standard ICNIRP or EU limits for occupational or general public exposure, already included by the software installation. In the Mode section you can select Electric 1 kV/m or Electric 100 kV/m or Magnetic 100uT or Magnetic 10mT.

Once the Weighted Peak has been enabled, the software shows the result 4.10.3 Weighted Peak of the calculation and its graph over the time. mode Result in percentage over the set hold time The User can set the Hold Time (in milliseconds): The Hold Time is the time resolution of the graph.
Page 54
The minimum hold time is of 500 milliseconds. The maximum is 10 minutes. The time span of the graph is 200 times the hold time. The rolling measurement memory deletes all values that date back longer than the set time period. The limit selected is shown in the higher right corner of the graph.
