(as a system)
The provisions of ETSI EN 301 489-1 [1], clause 4.2.5 shall apply.
The normal test modulation shall be transmitted by the test system and looped back in the radio equipment, as described
in ETSI EN 300 175-3 [4] clause 7 and clause 12 and ETSI EN 300 176-1 [5] clause 13. Further, the output of the radio
equipment under test shall be monitored by the test system.
4.3 RF exclusion band of radio communications equipment
4.3.1 Introduction
The provision of ETSI EN 301 489-1 [1], clause 4.3.1 shall apply.
4.3.2 Exclusion band for transmitters or the transmitter part of transceivers
4.3.2.1 General
The relevant requirements are based on DECT technology and not on additional technical capabilities of the DECT
equipment. The exclusion band for transmitters is directly related to the emissions due to transmitter transient
requirement of the DECT system. The relevant requirements and details are found in the harmonised standard ETSI
EN 301 406 [i.4], clause 5.3.6.3.
Because the used channel cannot be fixed or predicted during measurements, the transmitter exclusion bands have to be
defined at both edges of the allocated frequency band.
4.3.2.2 Channelized Systems
The exclusion band shall be from 1 874,016 MHz to 1 905,320 MHz (+7,776 MHz from the carrier close to the upper
band edge and -7,776 MHz from the carrier close to the lower band edge of the allocated band).
NOTE: The value of 7,776 MHz above is derived using the formula in clause 4.3.3.1 of ETSI EN 301 489-1 [1]
where the value of n is 4,5.
4.3.3 Exclusion band for receivers or the receiver part of transceivers
The exclusion band for receivers and receiver sections of transceivers is the band of frequencies over which no
immunity tests with radiated RF are made.
The following requirements are based on the measurement procedure and the DECT technology but not on additional
technical capabilities of the DECT equipment:
• The exclusion band shall be from 1 829 MHz to 1 951 MHz (+51 MHz from the upper band edge
and -51 MHz from the lower band edge of the allocated band).
ETSI
---------------------- Page: 9 ----------------------
10 ETSI EN 301 489-6 V2.2.1 (2019-04)
NOTE: The value of 51 MHz above is caused by channel independent effects, so the receiver exclusion band is
based on the band edge frequencies. Because of the equipment used to perform the measurement in ETSI
EN 301 406 [i.4], clause 4.5.7.4, a handover (change of channel and/or timeslot) is not possible a
±51 MHz exclusion band for receivers is needed.
4.4 Narrow band responses on receivers or receivers which are
part of transceivers
The provision of ETSI EN 301 489-1 [1], clause 4.4 shall apply with the following modifications.
No immunity tests shall be carried out on frequencies of identified narrow band responses i.e. spurious responses, of the
receiver parts of cordless telephone and similar communications equipment.
For DECT receivers, the identification criteria for narrow band responses are an increase of the speech output signal
level for speech equipment, or an increase in the Bit Error Ratio (BER) of the looped back data from the EUT for
non-speech equipment.
The nominal frequency offset to be used for the identification of narrowband responses shall be ±2 MHz for the first
part of the identification procedure, and ±2,5 MHz for its second part.
4.5 Normal test modulation
The provision of ETSI EN 301 489-1 [1], clause 4.5 shall apply with the following modifications.
For all types of DECT equipment the wanted input signal shall be a Radio Frequency (RF) carrier set to the nominal
centre frequency of one of the DECT RF channels, using Gaussian shaped frequency-shift keying (BT = 0,5) and
modulated with a 1 152 kbit/s bit sequence.
The encoding of the bit sequence shall conform to the encoding specified in ETSI EN 300 175-2 [3], clause 4 and ETSI
EN 300 175-3 [4], clause 7.
The parts of the data sequence that shall transmit a bit sequence conforming to the D-M2 pattern as specified in
Recommendation ITU-T O.153 [2] are those which are looped back according to the loop back test message described
in ETSI EN 300 175-3 [4], clause 12.4.
The burst timings of this carrier shall conform to the limits specified in ETSI EN 300 175-2 [3], clause 5.2.
