Foreword
This amendment to ETS 300 328 (1996) has been produced by the Radio Equipment and Systems (RES)
Technical Committee of the European Telecommunications Standards Institute (ETSI).
ETS 300 328, as amended by this amendment, together with ETS 300 826 is intended to become a
Harmonized Standard, the reference of which is intended to be published in the Official Journal of the
European Communities, referencing Council Directive 89/336/EEC (EMC Directive).
Annex E contains the ERC Decision which references the technical specifications in this ETS for inclusion
in national type approval regulations. This ERC Decision has been adopted following public consultation.
The final ERC Decision will be included in this amendment when it has been published by the ERC.

Amendments
Page 5, Foreword
Replace the first paragraph with the following:
This European Telecommunication Standard (ETS) has been prepared by the Radio Equipment and
Systems (RES) Technical Committee of the European Telecommunications Standards Institute (ETSI).
This ETS, together with ETS 300 826 is intended to become a Harmonized Standard, the reference of
which is intended to be published in the Official Journal of the European Communities, referencing
Council Directive 89/336/EEC (EMC Directive).
Insert the following after the last paragraph:
The technical specifications relevant to the EMC Directive are listed in annex D.
Annex E contains the ERC Decision which references the technical specifications in this ETS for inclusion
in national type approval regulations.
Page 18, subclause 7.2.1
Modify step 1, first bullet item to read:
".coupled to a matched diode detector"
Page 19, subclause 7.2.1
In step 2, second bullet item, first indented bullet item, add
"dBm"
after the formula.
Page 23, subclause 7.2.5
Replace paragraph beginning "For measuring emissions that exceed the level of 6 dB below the
applicable limit" with:
For further analysis of spurious emissions that exceed the level of 6 dB below the applicable limit, video
averaging shall be turned on, the resolution bandwidth shall be switched to 30 kHz and the span shall be
adjusted accordingly. If the level does not change by more than 2 dB, it is a narrowband emission; the
observed value shall be recorded in the test report. If the level changes by more than 2 dB, the emission is
a wideband emission and its level shall be measured and recorded in the test report.
It is stressed that the analyser settings given above are not suited for the measurement of wideband
emissions in dBm/Hz according to table 2. The method of measurement (in case of using a spectrum
analyser: the model and the settings) for the measurement for these emissions shall be documented in
the test report.
Replace the text in subclause 7.3.2 on page 24, starting with "Where these Measurements…." and until
the last sentence before clause 8, by
"For finding spurious emissions, the spectrum analyser shall be set as follows:
(table as given on page 24)
For further analysis of spurious emissions that exceed the level of 6 dB below the applicable limit, video
averaging shall be turned on, the resolution bandwidth shall be switched to 30 kHz and the span shall be
adjusted accordingly. If the level does not change by more than 2 dB, it is a narrowband emission; the
observed value shall be recorded in the test report. If the level changes by more than 2 dB, the emission is
a wideband emission and its level shall be measured and recorded in the test report.

It is stressed that the analyser settings given above are not suited for the measurement of the power
density of spurious emissions in dBm/Hz. The method of measurement (in case of using a spectrum
analyser: the model and the settings) for the measurement for these emissions, shall be documented in
the test report".
