6－2. EPS-02Ev3 Features＊

Measurement sensor is detected from the image for recognizing the measurement
location
The measurement object and measurement sensor are captured by a camera, and themeasurement sensor is found within the image for identifying the measurement location. The
recognized measurement location is a relative location within the camera image.
Any user-selected color can be specified for the measurement sensor. However, selecting acolor with the same tone as the background color will result in a reduced rate of recognitionand even mistaken recognition in certain cases.
The measurable range is the area shown in the camera, but it is restricted to a range that canbe recognized by the measurement sensor.

＊

Automatic control by software
Measurement sensor recognition from the camera image and control of the spectrum
analyzer are performed automatically. The measurement results can be output as a CSV file,and the image can be output in BMP format.

＊

Visual display of measurement results
The measurement strength distribution and camera image are displayed as a superimposed
image on the computer screen. Also, the mouse pointer in the image can be used to confirm
measurement results for any selected position.
In addition, an interpolation view of the surrounding strength can be used to provide easierassessment of the generation points.

＊

Full emission analysis function for measurement points
Data can be collected for the entire measurement frequency range generated from themeasured object in a single measurement. The emission map for each frequency band isalso redisplayed by simply specifying the frequency band.

6.Overview

6－3. Measurement Principle
The EPS-02 system performs two main operations for enabling visualization of the electromagnetic
field. First, it performs image recognition that identifies the measurement sensor location from therecording image. Second, it provides a color-coded distribution on the image indicating the strength of
the signals detected by the measurement sensor.
In image recognition, 640 x 480 pixel video from the camera is monitored in real time, and a
specific color only is extracted based on the specified parameters for "hue", "brightness", and"saturation". By finding the focal point of the area with the specific color, the location of the specificobject (measurement sensor) can be found in the image.
If an object with the same color as the specified color, but that is not the measurement sensor,
appears in the image, the measurement sensor location cannot be recognized correctly because thefocal point of all objects of this color is calculated. Therefore, the parameter settings for "hue","brightness", and "saturation" that are used to detect the measurement sensor, the brightness andlight exposure in the recording location, and selection of the lighting are important factors. Also, thecover of the measurement sensor must be adjusted based on the color of the measurement object.
Substances suitable for the measurement range are used for the measurement sensor, and aspectrum analyzer is used as the measuring instrument for enabling measurement of theelectromagnetic field area. The spectrum import count and frequency range vary depending on themeasurement sensor and measuring instrument. The measurement data is mapped to a position
specified by image recognition. The method of capturing data at the same position can be selectedfrom MAX HOLD, MAX PEAK DATA, FREE RUN, and SINGLE.
After measurement is completed, the frequency range that you want to view can be selected for
creating a strength distribution combined with the image.
There are no guidelines or restriction values for the electrical field strength of the proximity field.

7－2. Functions of Each Device① Web camera
This is a general-purpose web camera. The image of measurement object is captured andtransferred to the PC. The web camera is connected to the PC by a USB cable. If necessary, theconnection can be extended by a USB extension cable.
② Control PC
This enables running of system control software. This software imports images from the web
camera, identifies the measurement sensor within the image, and finds its location. After
frequency analysis is performed by the spectrum analyzer, the control PC receives themeasurement results and maps them to that location.
③ Spectrum analyzer
This performs frequency analysis of the signals from the measurement sensor and sends the
spectrum data to the PC. The spectrum analyzer is connected to the PC using the supplied GP-IB
or LAN cable.
④ Preamplifier (Optional)
This amplifies the signal detected by the measurement sensor. Connect the measurement sensor
to the INPUT terminal and the spectrum analyzer to the OUTPUT terminal.
⑤ Measurement sensor (Optional)
A sensor (probe) is used based on the measurement target frequency and electrical or magnetic
field. Attaching a special cover to the sensor is recommended for improving the recognition rate.

128. Preparation

CAUTION
Environments having poor signal reception
In environments exposed to extremely large amounts of external noise, the equipment may be unable
to realize its maximum performance.
Even when indoors, the equipment can be affected by lighting and other electronic devices. During
measurement, try to minimize the effect of the electromagnetic environment to prevent external noisefrom affecting the equipment. Also, certain PCs may generate large amounts of noise emissions andmay not be suitable for measurement systems.

8－1. System Backup
NoiseKen provides an optional service (additional charges apply) for installing the EPS-02Ev3
program in your PC before providing the program, but if the program is erased, install it from the
supplied setup media. Copy the content of the setup media to a hard disk, removable disk, or otherlocation and store it there in case of loss. For details of setup, see "10. Setup" (P90).

8－2. System Connections① Connect the web camera to the PC using the USB cable. Any commercially-available USB cable
can be used, but it must be a cable that supports the USB 2.0 standards. Be aware that the USB
2.0 standards limit the cables to a maximum of 1 extension and maximum length of 5 m.
② The spectrum analyzer and PC are connected by a LAN cable. A commercially-available cable
can be used for the LAN cable. Use a one-to-one local connection without passing through thesite LAN or hub.
③ Connect the measurement sensor and spectrum analyzer. Use the proper conversion cable thatmatches the sensor output connector.

Attenuator
An attenuation of input signal. A higher value reduces miss match reflection, and noise
floor level goes up.

Antenna Factor
When using Antenna Factor, check Enable Factor and select the file with the same name as theelectromagnetic field measurement sensor to be used.
In the initial state after installation, THROUGH is the only available antenna factor. The factor files
for the electromagnetic field probes (PN7405) are included on the attached setup media. To usethem, follow the steps below.
(1) Log into Windows using an ID having administrator privileges.
(2) Load the attached setup media, and open the FACTOR folder.
(3) Open the 00-00013A or 00-00019A folder according to your preamplifier.
(4) Copy the factor files (*.ant) in the folder to the folder where the EPS-02Ev3 executable file islocated (C:\Program Files (x86)\NoiseKen\EPS-02Ev3, under normal conditions).
This factor file is used for correction to make the frequency characteristics of the sensor flatness. It
is not for convert absolute field strength.
When the THROUGH file is selected or Enable Factor is unchecked, the spectrum data from thespectrum analyzer are acquired as it is, without interpolation.

Switch and Frequency Axis Switch can be changed.

Points (squares of the grid) that have been measured are color-coded according to the peak value
and overlaid on the camera image during measurement. In addition, the spectrum data measured
by the spectrum analyzer is displayed in the spectrum graph area located in the lower part of theView window, on a point-by-point basis.

If a directional sensor is used, maintain the same direction.
In addition, move the sensor parallel to the measurement object.

33

9.Operation Procedure

The EPS-02Ev3 software sends a sweep start command to the spectrum analyzer immediately
after the sensor is recognized. After completion of sweeping, the software recognizes the sensor
position again, and only when the sensor is found at the same point (position) where it was placedat the start of the analyzer sweeping, the spectrum data is stored.
If the sensor is moved quickly, the point at the start of sweeping differs from that at the completionof sweeping, and as a result, measurement data is not stored. For spectrum analyzers with slow
response speed, move the sensor more slowly.

If the sensor is not recognized or other object is falsely recognized, reconfigure the image
recognition setting. Click Image Recognition Setting from the Set menu to change the setting.
Please note that it is possible during measurement.

Note that if the noise level emitted from the EUT is high, the spectrum analyzer andpreamplifier may be damaged by excessive input.

63

9.Operation Procedure“Failed to generate a peak. The maximum number of peaks displayed is changed. If the failure
persists, closing other windows may improve the situation.”
Displayed when generation of the peaks that make up the 3D graph fails. When multiple viewwindows of spectrogram measurement are displayed, closing all of them and reopening theView window may improve the situation.

“Failed to create index buffer. The number of displayed data is limited.”
Displayed when creation of index buffer for displaying a 3D graph fails. The number ofdisplayed data to create index buffer is limited.

“Some data are not displayed because the maximum number of displayed peaks is exceeded.”
In EPS-02Ev3, since the upper limit of the number of peaks that make up the spectrogram isset, when the set value is exceeded, only a part of the spectrogram is displayed, resulting in
the appearance of this message. The upper limit of the number of peaks changes dependingon the hardware performance as well.

“The addition of sweep data is temporarily stopped because the sweeping speed exceeds thedata saving speed.”
Displayed when the speed for acquiring data exceeds the speed for saving data in the file, andthe data acquisition is temporarily stopped.

“There is data exceeding the specified sweep start interval.”
Displayed when there is data that cannot be acquired at the specified interval whenmeasurement is performed with the sweep start interval set to the specified interval.

“As the display time range exceeds the data range in the memory, some data may not be
displayed.”
Displayed when the display time range of the 3D graph exceeds the data range in the memory,and some data may not be displayed. To display the data, the display time range needs to be
shortened. For the change of the display time range, refer to “Axis Display Settings” on page69.
