pertaining to these essential IPRs, if any, is publicly available for ETSI members and non-members, and can be found
in ETSI SR 000 314: "Intellectual Property Rights (IPRs); Essential, or potentially Essential, IPRs notified to ETSI in
respect of ETSI standards", which is available from the ETSI Secretariat. Latest updates are available on the ETSI Web
server (https://ipr.etsi.org/).
Pursuant to the ETSI IPR Policy, no investigation, including IPR searches, has been carried out by ETSI. No guarantee

Foreword
This Technical Specification (TS) has been produced by ETSI Technical Committee Electromagnetic compatibility and
Radio spectrum Matters (ERM).
Modal verbs terminology
In the present document "shall", "shall not", "should", "should not", "may", "need not", "will", "will not", "can" and
"cannot" are to be interpreted as described in clause 3.2 of the ETSI Drafting Rules (Verbal forms for the expression of
provisions).
"must" and "must not" are NOT allowed in ETSI deliverables except when used in direct citation.
Introduction
The radar level gauges covered by the present document do not use the signal form of time domain UWB short pulses.
Instead, they use the frequency domain based FMCW and/or SFCW waveforms. Thus the emission bandwidth
generated by the FMCW and/or SFCW radars is strictly controlled by the equipment itself.
The specified requirements in the present document describe the worst case scenario (i.e. the possible highest emissions
outgoing to the environment and incoming from interferer signal sources [10]) and is seen as a feasible test method to
prove compliance of radar level gauging applications in stillpipes.
The background and related applications have been described in ETSI TR 102 750 [i.2] where the applications have
been considered indoor like systems.
The purpose of revision of the present document is to update the previous version ETSI TS 102 692 (V1.1.1) [i.10] to
cover the essential requirements of article 3.2 of the Directive 2014/53/EU [i.3].
