Introduction
After having mapped what you needed to measure you can open the Viewer application.
You'll first be able to import your data to visualize them.

However its function isn't limited to a simple viewer, it allows you to export your datas in a PDF format and get an effective measurement report. On this report you can manage to get the frequency peaks of your measures and visualize where they come from for exemple.

Datas format

Now that you've done your measures you can manage to view them by following simple steps


1. Click on the folder symbol
2. Click on the " + " on Data 1 or 2
3. Select the file you've measured and which you want to analyse

LXD = ZIP = XML + JPG + DAT

The .lxd file contains 3 types of files : .xml .jpg and .dat which are described under

How to unzip the LXD file ?

1 - Put the LXD file on your PC

2 - Rename it (You have to replace .LXD by .ZIP)

3 - Unzip and put the 3 files in a dedicated directory that you can create. The .XML file is inside

XML Format

1. XML norm in NFS (Near Field Scan)

Near-field scan measurements and simulations generate a large amount of data. The format of the data is closely linked to the supplier of the acquisition or simulation software, rendering extremely difficult its exchange between suppliers, customers, EDA tool vendors, academics, etc.

The XML / NFS (Near Field Scan) standard: TR 61967-1-1 © IEC: 2010 will define a universal exchange format for data from different near-field scanners . Its format is suitable for different 2D or 3D coordinate systems for a frequency or time domain.

If needed you can get more informations here : https://ieeexplore.ieee.org/document/5284701

2. Measurement informations in text-based format.

  • datas
  • configuration
  • setup (ex: probe or sensor used)

3. Example : Emission comparison between a power supply with and without cover using .xml datas

DAT Format

Measurement informations in a binary text file, the .dat gives a planar representation (x,y,z axis) and frequency information

OBJ + FFS

- FFS format : FarField Source : Corresponds to a simulation and comes from CST Studio http://www.mweda.com/cst/cst2013/mergedProjects/CST_CABLE_STUDIO/special_solvopt/special_solvopt_farfield_source.htm

- OBJ format : Object representation in 3D (SketchUp, 3DMax...)

Example : Horn antenna simulation with its emission

Options

Transparency adjustment

By opening the 2nd tab you'll be able to custom the transparency of the measures. It can be useful to put into evidence where the waves are coming from.

Another way to set the transparency is available while using the frequency option of the EM-ScanPhone, simply slide that small tab

Color choice

Changes the color scale.

Graphs

Max and Frequency information

In this menu you get an additionnal frequency information, it allows you to see the amplitude measured corresponding to each frequency.
