Copyright © 2008 – 2019 DARE!! International Page 5
WARNINGS & PRECAUTIONS
The RadiSense system is a closed loop fibre system and therefore classified as a Class 1M laser
system according to EN60825-1:2014 and EN60825-2:2005. In order to provide laser safety in
case of a fibre failure or accidental disconnection of the fibres, the RadiSense system is provided
with an Automatic Laser Shutdown (ALS) as described in the EN60825-2:2005.
Although the RadiSense system does not emit any laser light under normal
circumstances, it is good common practice never to look into any of the fibre
optic connectors.
As a safety precaution, products that use a LASER can only be turned on using
a LASER Code. This code can be entered using the touchscreen of the
RadiCentre system.
(In combination with the RadiCentre CTR1004B or CTR1009B)
As a safety precaution, products that use a LASER can only be turned on by
pressing the ‘START’ button of the RadiCentre system for several seconds. An
auditory warning will sound during this activation period.
(In combination with the RadiCentre CTR1001S)
Make sure that the fibre cables are installed correctly before activating the
system. Do not activate the system if the fibre optic cables show any sign of
damage or tampering.
To make the RadiSense as safe as possible, the plug-in card and sensors have
their own safety interlock system that is designed to work with the RadiCentre.

1. Introduction
1.1 Product Introduction
The RadiSense 10 E-field sensor is the most accurate ultra-wideband sensor designed for electric
field strength measurements. The sensor is small and fully optically isolated to minimize field
perturbation.
Applications for the E-field sensor are:
 Radiated immunity field monitoring
 Anechoic chambers calibration
 Field homogeneity measurements
 RF broadcast and welding radiation-hazard monitoring
 Long term field monitoring
1.2 Related Products
RadiCentre system
The RadiCentre is a modular EMC test system that serves as
the user and computer interface for all the RadiCentre plug-in
cards and modules (such as the RadiSense field sensor).
RadiMation software
RadiMation is the EMC software package from DARE!!
Instruments used for remote control and automated testing of
the RadiCentre plug-in cards and modules (such as the
RadiSense field sensor).

2. The RadiSense
2.1 Product Characteristics
LASER Powered - The sensor is LASER powered without the need for batteries. This allows 24-7
continuous testing at maximum performance without the need to change or recharge batteries.
Superb Measurement Accuracy – To perform accurate field measurements, the E-field sensor
dimensions must be as small as possible compared to the wavelength of the measured signal.
There are two reasons for this:
 First, because large sensor dimensions cause the sensor to resonate at lower frequencies
and therefore causes measurement inaccuracies.
 Secondly, to maintain field uniformity in an anechoic chamber. The smaller the sensor,
the better the obtainable resolution for field homogeneity measurements.
In TEM and G-TEM cells, sensor dimensions above 10 cm are large compared to the dimensions
of the homogenate field area.
The sensor dimensions of the RadiSense 10 are extremely small, increasing measurement
accuracy. In addition, the RadiSense 10 is equipped with 2 antennas per axis (6 in total) to
optimize isotropic performance and achieve best overall accuracy.
As part of the ISO9001 quality procedure each RadiSense 10 field sensor is factory adjusted and
verified, where default linearity adjustment data is stored inside the RadiSense 10 field sensor.
User correction - calibration factors
Additionally, the RadiSense 10 field sensor has capabilities to store “user correction factors”
inside the field sensor. By applying calibration factors in the sensor itself, there is no risk one
forgets to apply the frequency correction data when performing manual or automated tests.
The frequency response correction factors which are determined during ISO17025 accredited
calibration of the probe can be stored inside the field sensor using the RadiMation device driver.
Please refer to paragraph 5 of this manual for further instructions.
When the user correction data is stored inside the probe the RadiSense 10 field sensor will return
corrected E-field readings without the need of additional calculations1. Corrections will be applied
inside the probe for each individual axis.
NOTE: If a calibration is performed at DARE!! Calibrations, the correction factors will NOT be
loaded into the RadiSense 10 field sensor by default by DARE!!
1 Please note, the frequency of the measured field must be send to the sensor in order to apply the correct, frequency
dependent, “user calibration factor”.

2.3 Fibre Optic Cables
Use an extension fibre to connect the sensors to the plug-in card mounted in the RadiCentre.
This extension fibre is a robust duplex fibre cable and uses dissimilar connectors to avoid
misconnections. The fibre optic cable with FC connectors feeds LASER light to the field sensor.
The fibre optic cable with ST connectors is used for bi-directional data communication between
the field sensor and the plug-in card.
Refer to chapter 2.6 for fibre handling and maintenance.
To ensure safe and correct operation of the sensor, only use the RadiSense with the original
supplied or ordered fibres. Do not use other fibres than those supplied by DARE!! Instruments.
Fibre extension cables with different lengths up to 100 meters are available on request.
Contact your local reseller for more detailed information.
2.4 RadiSupply Plug-In Card, Rear Panel
The following connections and indicators are found at the back panel of the RadiSupply plug-in
card:
POWER ON: This green LED lights up when the power is on and the
interlock is closed2.
LASER APERTURE: Connect to the E-field sensor through the fibre
extension cable with FC connectors.

2.5 LASER Safety Measures
The RadiSense uses a high-power LASER to supply energy to a remote measuring device. The
wavelength of this LASER is approximately 808nm. This infrared laser is invisible to the human
eye.
During normal operation, exposure to LASER radiation is not possible because the RadiSense
uses a fibre-coupled closed loop system with Automatic Laser Shutdown (ALS). However, we ask
that you comply with the following precautions for your own safety:
NEVER look into any of the fibre optic connectors. The LASER emits a
beam that is invisible to the naked eye. Such light may cause permanent
eye damage. Avoid eye or skin exposure to direct or scattered radiation.
 Assign a ‘LASER safety officer’ in your company. The ‘LASER safety officer’ is
responsible for reviewing the safety precautions.
 Check and connect all fibre cables before activating the system.
 Do not activate the system if the fibre optic cables show any sign of damage or
tampering.
 The RadiCentre system is equipped with a remote interlock system. This interlock
system prevents inadvertent LASER radiation. For example, to prevent LASER
radiation when someone enters a shielded room and steps on a fibre.
 The remote interlock connection should be connected to an ‘emergency master
disconnect’ and in series with the room door or fixture interlocks.
 A visual ‘LASER ON’ indicator LED will light up when the LASER is activated. This
LED on the front panel of the RadiCentre system serves as a reminder to the
operator that one or more LASERS are switched on.

Copyright © 2008 – 2019 DARE!! International Page 11
RadiCentre 2-slot and 7-slot specific:
 A ‘LASER Code’ is required to activate the RadiCentre 2-slot and 7-slot systems. This
LASER code enables the power supply to all installed (LASER) modules.
 (Please refer to Chapter 3.2 for the default laser code).
 To prevent accidental activation of the LASER, an ‘Acknowledge’ button will appear
directly after the LASER ‘Start’ button is pressed. The LASER will only be activated if
this button is pressed within the ‘4 seconds timeframe’.
RadiCentre single-slot specific:
To start the RadiCentre 1-slot system (which has no touchscreen display),a specific activation
procedure combined with auditory warnings is used.
To activate the LASER in the RadiCentre Single, follow these steps:
1. Press the ‘Start’ button on the back panel (of the RadiCentre) and hold it for at least
3 seconds.
2. Five loud ‘beeps’ can be heard; four short beeps followed by one long beep.
3. On the fifth ‘beep’ the LASER link is activated and the red ‘LASER ON’ LED (on the
RadiSupply card) lights up.
4. Release the ‘Start’ button.
This means that:
 If you want to interrupt the activation process, all you have to do is release the
‘Start’ button (before the fifth ‘beep’). The LASER will not be activated.
 If you are interrupted during the activation process (and release the ‘Start’ button
by accident), the LASER will not be activated.
 If you press the button by accident (and do not wish to activate the LASER), the
auditory warning will alert you to this action.
To prevent accidental activation of the LASER, an auditory warning will alert you of the
LASER activation procedure (if the ‘Start’ button is being pressed). To interrupt the
activation process, all you must do is release the ‘Start’ button.

2.6 Fibre Handling and Maintenance
The fibre optic cables in the RadiSense are a crucial part of the system. Improper handling and
poor maintenance can cause deterioration or permanent damage. Please read the following
handling and maintenance guidelines to ensure both your safety and the quality of the product.
2.6.1 Handling guidelines
 Always place the plastic end-caps on the fibre connectors when they are not in use.
Only use the supplied end caps.
 Never touch the tip of the fibre connector (core surface). If the tip of the connector
is touched, use the supplied alcohol wipes to clean it before usage!
 Never drop the fibre connectors, as this may damage the core surface.
 Never bend the fibres (exceed the minimum bend radius <5 cm), as this will break
the fibre core.
 Never pull the fibre connector out of a coupling by its orange jacket, always use the
connector.
 Fasten the connectors by hand only, never use tools.
 Do not stand on or crush the fibres.
 Do not apply mechanical stress (pull) to the fibres.
 Switch off the system before detaching the fibres.
2.6.2 Maintenance guideline
Clean the contact surface of the fibres with the lint-free alcohol wipes before installation.
Do not use other solvents or wipes. Fibres are clean and polished on delivery and do not
need to be cleaned when installed for the first time, when the handling guidelines as
defined in chapter 2.7.1 are properly followed.

Copyright © 2008 – 2019 DARE!! International Page 13
2.6.3 Fibre conditions
Use the examples and instructions in the following figure as a guideline for further fibre
maintenance. If you have doubts about the condition of the fibre optic cables, please contact your
local reseller or DARE!! Instruments for assistance and/or advise.

Copyright © 2008 – 2019 DARE!! International Page 14
2.7 Probe stand
The RadiSense 10 is supplied with a PST2000A probe stand consisting of the following parts:
 Base
 Feet (3 pcs)
 Pole (3 pcs)
 Angle mount
The probe stand parts can be easily assembled together. The 3 feet can be screwed into the side
of the base. The probe stand can also be used without these feet. Three poles with different size
are delivered to mount the probe at either 50 mm, 100 mm or 150 mm height. Screw the pole
into one of the two holes of the base. Using this appropriate probe stand pole with the feet, the
probe is automatically positioned at the desired height above the surface and can be easily
positioned 100 mm from the edge of a table.

Copyright © 2008 – 2019 DARE!! International Page 15
The use of the mounting angle is optional. For isotropic measurements of an electrical field of
which the polarization is unknown (for example in reverb chamber / mode-stir chambers) the
mounting angle is not needed, see left picture.
For accurate measurements of electrical field with a known polarization, the mounting angle can
be used to position one axis of the RadiSense parallel to the field. See right picture.
In most situations, this is the way an E-field sensor is calibrated, axis by axis. Therefore, the probe
should be used in the same way to obtain the most accurate results.
REMARK:
Please be noted that placing dielectric material in close proximity to the field sensor will influence
the field and could cause measurement errors.
