4 Test conditions
4.1 General
For the purposes of the present document, the test conditions of ETSI EN 301 489-1 [1], clause 4 shall apply as
appropriate. Further product related test conditions for amateur radio and ancillary equipment are specified in the
present document.
For emission and immunity tests, the test modulation, test arrangements, etc., as specified in the present document,
clauses 4.1 to 4.5 of the present documment shall apply.
The general test conditions for amateur radio equipment are as follows:
• transmitters and amplifiers shall be tested in stand-by (if applicable) and in transmit mode of operation;
• transceivers and transverters shall be tested in receive, stand-by, and transmit mode of operation;
• if integral antenna equipment provides an internal antenna connector for testing purposes, then the tests can be
made via that connector.
The manufacturer shall recommend a power supply (e.g. an AC/DC power adapter) for use in conjunction with the
equipment under test (EUT), to ensure satisfactory operation of the combination during the EMC tests. When a range of
different types of power supply units can be used with several types of that manufacturer's radio equipment, then each
type of power supply unit shall be tested with the radio providing the highest RF output Peak Envelope Power (PEP).
These power supply units shall then be listed as preferred items for future generations of that manufacturer's radio
equipment.
The EMC tests shall be performed with the EUT set to the following operation frequencies:
• ingle-band equipment:
- test with the operation frequency set to the centre of the operation frequency band;
• double-band equipment:
- test with the operation frequency set in sequence to the centre of each operation frequency band;
• HF multiband equipment or VHF/UHF multiband equipment:
- test with the operation frequency set in sequence to the centre of the lowest, middle, and highest HF
operation frequency band;
• HF/VHF, HF/UHF or HF/VHF/UHF combined equipment:
- test with the operation frequency set in sequence to the centre of the lowest HF band, the middle HF
band, the highest HF band, the lowest VHF/UHF band, the middle VHF/UHF band, and the centre of the
highest VHF/UHF band.
4.2 Arrangements for test signals
4.2.1 Arrangements for test signals at the input of transmitters
The provisions of ETSI EN 301 489-1 [1], clause 4.2.1 shall apply with the following modifications.
If possible, the transmitter should be modulated with a suitable signal, from an internal or external signal source. If it is
not appropriate to get a modulated RF signal from the transmitter, then the tests may be performed using its
unmodulated carrier.
It shall be possible to verify that a communications link is established and maintained.
ETSI
---------------------- Page: 8 ----------------------
9 ETSI EN 301 489-15 V2.2.1 (2019-04)
4.2.2 Arrangements for test signals at the output of transmitters
The provisions of ETSI EN 301 489-1 [1], clause 4.2.2 shall apply with the following modifications.
The transmitter under test shall be modulated such that the maximum PEP output is achieved, either by single or
multiple tones, or by a suitable bit stream, or in case of transmitters for other than analogue voice or data transmission,
by a test modulation representative of normal use (see also clause 4.5). The manufacturer shall declare the normal test
modulation.
Where thermal limitations prevent continuous transmission under such conditions, the tests may be performed using
gated methods. Under these circumstances, the test method used shall be recorded in the test report.
4.2.3 Arrangements for test signals at the input of receivers
The provisions of ETSI EN 301 489-1 [1], clause 4.2.3 shall apply with the following modifications.
The receiver shall be provided with a wanted RF input signal chosen according to clause 4.2.3 of ETSI
EN 301 489-1 [1] set to its operation frequency, and modulated with a suitable modulation signal fitting the
communication system characteristics (see clause 4.5.2). If it is not appropriate to provide the receiver with a modulated
wanted RF input signal, the test may be performed using an unmodulated wanted RF input signal.
If possible, the wanted RF input signal to establish a communications link shall be presented to the antenna connector
by a coaxial cable. The wanted RF input signal shall be set to a nominal value of 60 dB (or a lower value as declared by
the manufacturer) above the maximum usable sensitivity of the EUT, as declared by the manufacturer in the product
documentation.
It shall be possible to verify that a communications link is established and maintained.
4.2.4 Arrangements for test signals at the output of receivers
The provisions of ETSI EN 301 489-1 [1], clause 4.2.4 shall apply.
4.2.5 Arrangements for testing transmitter and receiver together
(as a system)
The provisions of ETSI EN 301 489-1 [1], clause 4.2.5 shall apply with the following modification.
These arrangements are only applicable for duplex transceivers. The wanted RF input signal, coupled to the receiver,
shall be modulated with a suitable test signal (see clause 4.5.3). The transmitter shall be operated at its maximum PEP
RF output, modulated with the test signal, coupled to the transmitter from the output of the receiver (repeater mode).
4.3 RF exclusion band of radio communications equipment
4.3.1 Exclusion band for receivers or the receiver part of transceivers
The exclusion band for a receiver and the receiver part of a transceiver is determined by the characteristics of the
equipment.
For receivers operating on a fixed single frequency, the exclusion band extends from -5 % to +5 % of that fixed single
operation frequency.
For receivers operating or capable of operating, on a number of spot frequencies in a narrow operating frequency band
which is less than 20 % of the centre frequency of the operating band, the exclusion band extends from -5 % of the
lowest frequency of the narrow operating frequency band to +5 % of the highest frequency of that band.
For receivers operating, or capable of operating on a number of spot frequencies over a wide frequency band, the
exclusion band for each of the wanted RF signal test frequencies shall extend from -5 % to +5 % of each wanted RF
signal test frequency.
ETSI
---------------------- Page: 9 ----------------------
10 ETSI EN 301 489-15 V2.2.1 (2019-04)
NOTE: The exclusion bands are derived using different methodologies from those described in clause 4.3.3 of
ETSI EN 301 489-1 [1]. However, the used methodologies lead to narrow exclusion bands for every
amateur radio frequency band .The parameter n in the formulas derived in ETSI EN 301 489-1 [1]
calculates in any case smaller than 1.
4.3.2 Exclusion band for transmitters or the transmitter part of transceivers
4.3.2.1 Exclusion band for EMC emission measurements
For EMC emission measurements, the exclusion band for transmitters shall be determined considering the class of
emission characteristics of the EUT. For EMC emission measurement purposes, the bandwidth of the exclusion band
shall additionally allow for the skirt bandwidth (Fb) of the measuring instrumentation, as shown in table 1.
Table 1: Transmitter exclusion band for emissions
Necessary bandwidth of emission Exclusion band Centre of the exclusion band
Fn < 0,05 Fc 3 Fn + Fb Fc
Fn > 0,05 Fc 1,1 Fn + Fb Fc
Where:
• Fn = necessary bandwidth of the wanted class of emission as defined in ITU Radio Regulations [i.3],
clause 1.152;
• Fb = 200 kHz in the frequency range below 30 MHz;
• Fb = 2 MHz in the frequency range above 30 MHz;
• Fc = centre frequency of the transmitter necessary bandwidth.
4.3.2.2 Exclusion band for immunity tests
For immunity tests, the exclusion band for transmitters extends plus and minus twice the maximum occupied bandwidth
allowed for the type of service for which the equipment is intended to operate, centred around the occupied bandwidth.
NOTE: The exclusion bands are derived using different methodologies from those described in clause 4.3.2 of
ETSI EN 301 489-1 [1]. However, the used methodologies lead to narrower exclusion bands for every
amateur radio frequency band.
4.4 Narrowband responses of receivers or receivers which are
part of transceivers
The provision of ETSI EN 301 489-1 [1], clause 4.4 shall apply.
4.5 Normal test modulation
4.5.1 Transmitters
For the transmitter under test, the manufacturer shall declare the normal test modulation taking due account of the
following requirements:
• AM transmitters:
- the normal modulation signal shall consist of a single sinusoidal modulation signal, causing a modulation
depth to the rated value.
