system: ULP-AMI together with an associated ULP-AMI-P)
The provisions of EN 301 489-1 [1], clause 4.2.5 shall apply with the following modification:
The transmitter of an ULP-AMI and the receiver of an associated ULP-AMI-P or the receiver of an ULP-AMI and the
transmitter of an associated ULP-AMI-P may be tested together, if appropriate and agreed by the manufacturer and the
test laboratory (size of devices, etc.).
In this case both EUTs shall be located in their respective test environment and exposed simultaneously to the EMC
phenomena.
4.3 Exclusion bands
The emission measurement and immunity test exclusions are referred to as "exclusion bands" and are defined in the
clauses 4.3.1 and 4.3.
The frequency, on which the EUT is intended to operate, shall be excluded from conducted and radiated RF immunity
tests.
The frequency on which the transmitter part of the EUT is intended to operate shall be excluded from emission
measurements when performed in transmit mode of operation.
During emission measurements, a frequency exclusion band does not apply for the receiver part of ULP-AMIs and/or
associated ULP-AMI-Ps.

4.3.1 Exclusion bands for receivers
The exclusion band for receivers (including receivers that are part of transceivers) is determined as follows:
- for receivers capable of operating on only one single frequency and not having an alignment range, the lower
frequency of the exclusion band is the lower frequency of the used frequency channel minus the extension
value given in table 1, and the upper frequency of the exclusion band is the upper frequency of the used
frequency channel plus the extension value given in table 1. The calculated extension value shall be based on
the operating frequency;
- for receivers capable of operating on more than one frequency and having an alignment range, the lower
frequency of the exclusion band is the lower frequency of the alignment range minus the extension value given
in table 1, and the upper frequency of the exclusion band is the upper frequency of the alignment range plus
the extension value given in table 1. The calculated extension values shall be based on the centre frequency of
the alignment range;
- for wide band receivers, i.e. receivers operating in a non-channelized arrangement, the lower frequency of the
exclusion band is the lower frequency of the intended operating band minus the extension value given in
table 1 and the upper frequency of the exclusion band is the upper frequency of the intended operating band
plus the extension value given in table 1, or the total exclusion band is twice the intended operating frequency
band of the receiver centred around the centre frequency of the intended operating band, whichever is the
greater.

o o o
NOTE: Measurements shall not be carried out below 150 kHz.

4.3.2 Exclusion band for transmitters
For wide band transmitters, i.e. transmitters in a non-channelized frequency band, the exclusion band is twice the
intended operating frequency band (i.e. 315 kHz or less) centred on the centre frequency of the intended operating
frequency band.
In case the receiver and transmitter are tested together as a system (see clause 4.2.5) the exclusion band defined for
receivers or the exclusion band defined for transmitters shall be used, whichever is greater.
4.4 Narrow band responses of receivers
The provision of EN 301 489-1 [1], clause 4.4 shall apply.
4.5 Normal test modulation
The RF carrier shall be modulated with a test signal that produces specific selective messages or commands as stated by
the manufacturer, representing a practical selection of usable selective messages/commands. The manufacturer shall
declare the format of the modulation signal and any error detection and correction involved. Where transmitters do not
have a modulation input port, the internal equipment modulation is used.
