Foreword
This Technical Report (TR) has been produced by ETSI Technical Committee Electromagnetic compatibility and Radio
spectrum Matters (ERM).
The present document contains only the test procedure description, based on the requirement catalogue in annex E and
the Technical Specification on DAA enabled UWB devices. The physical test configurations and test results are not
included as no DAA UWB devices were available for test during the lifetime of the task force. The report will be
updated with the corresponding physical test setups and test results as soon as a stable body of information becomes
available.
Introduction
The present document describes a set of tests to evaluate the response of UWB devices equipped with Detect and Avoid
algorithms in the presence of Radar signals in the range 3,1 GHz to 3,4 GHz and 8,5 GHz to 9 GHz and BWA systems
in the range 3,4 GHz to 3,8 GHz.
The present document identifies the general test criterion and operational states of the UWB device under test as well as
the test signal definition for the potential victims, namely radiolocation systems and BWA systems.

4 Recommended Applicability of Test Descriptions
The test descriptions are derived from the requirement catalogue based on the technical specification TS 102 754 [i.5].
The essential elements of this requirement catalogue have been recorded in annex E.
The applicability of each individual test description is identified in table 1 and cross referenced to the requirements
catalogue. The applicability of test descriptions is formally expressed by the use of Boolean expression that is based on
(ICS) parameters included in annex F.
NOTE: The applicability is just a recommendation based on the purpose for which the test description was
written.
The columns in table 1 have the following meaning:
TD Id:  The TD Id column indicates the test description identifier.
RQ Id:  The RQ Id column gives the requirement catalogue cross reference.
Summary: The Summary column is the summary field of the test description.
Applicability: The following notations are used for the applicability column:
M mandatory - the test case is mandatory.
O optional - the test case is optional.
N/A not applicable - in the given context, the test case is not recommended.
O.i qualified optional - for mutually exclusive or selectable options from a set. "i" is an integer which
identifies a unique group of related optional items.
C.i conditional - the test is recommended ("R") or not ("N/A") depending on the support of other
items. "i" is an integer identifying a unique conditional status expression which is defined
immediately following the table. For nested conditional expressions, the syntax "IF . THEN (IF .
THEN . ELSE.) ELSE ." is used to avoid ambiguities.
Comments: This column contains a verbal description of the condition included in the applicability column.

5 Test Configurations
5.1 Introduction
In this clause the two basic test configurations will be presented and described. The test setup can be split into a
conducted and a radiated test setup. A general example for the test set-up for the conducted test is given in figure 1 and
for the radiated test in figure 2.
Due to the very low levels to be measured the conducted test setup is the preferred setup up. Nevertheless, a radiated
setup will be needed in case of devices with integrated antennas, non accessible antenna connectors and devices
deploying antenna techniques as an avoidance technique.

5.2 General Test conditions
This clause covers the general laboratory requirements for power supply, environmental conditions, as well as the
operational requirements for the UWB devices under test.
5.2.1 Test conditions
Testing is performed under normal test conditions.
The test conditions and procedures are be performed as specified in the following clauses.
5.2.2 Power sources
5.2.2.1 Power sources for stand-alone equipment
During testing, the power source of the equipment ise replaced by a test power source capable of producing test
voltages as specified in clause 5.2.3.2. The internal impedance of the test power source should be low enough for its
effect on the test results to be negligible. For the purpose of tests, the voltage of the power source is measured at the
input terminals of the equipment.
For battery operated equipment the battery is removed and the test power source is applied as close to the battery
terminals as practicable.
During tests the power source voltages are maintained within a tolerance of ±1 % relative to the voltage at the
beginning of each test. The value of this tolerance is critical to power measurements; using a smaller tolerance will
provide better measurement uncertainty values.
5.2.2.2 Power sources for plug-in radio devices
The power source for testing plug-in radio devices is provided by a test fixture or host equipment.
Where the host equipment and/or the plug-in radio device is battery powered, the battery may be removed and the test
power source applied as close to the battery terminals as practi
