The equipment shall comply with all the technical requirements of the present document at all times when
29、 operating within the boundary limits of the required operational environmental profile. 4.2 EUT test frequencies Testing shall be performed with the EUT set to frequencies as follows: single-band equipment: test at the centre of the band; double-band equipment: test at the centre of both bands; HF
30、multi-band equipment or VHF/UHF multi-band equipment: test at the centre of the lowest, the centre of the middle, and the centre of the highest band; ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 8 HF/VHF, HF/UHF or HF/VHF/UHF combined equipment: test at the centre of the lowest HF band, the centre of the
31、 middle HF band, the centre of the highest HF band, the centre of the lowest VHF/UHF band, the centre of the middle VHF/UHF band, and the centre of the highest VHF/UHF band. 4.3 Test power source During testing the power source of the equipment shall be replaced by a test power source capable of pro
32、ducing the nominal supply voltage for the equipment as declared by the manufacturer. The internal impedance of the test power source shall be low enough for its effect on the test results to be negligible. For the purpose of tests, the voltage of the power source shall be measured at the input termi
33、nals of the equipment. For battery operated equipment the battery shall be removed and the test power source shall be applied as close to the battery terminals as practicable. During tests of DC powered equipment the power source voltages shall be maintained within a tolerance of 1 000 MHz -47 dBm (
34、see note) NOTE: For measurement at frequencies greater than 40 GHz no test limits are specified. Where limits are stated using dBc, the reference level is PX, measured at the antenna port according to clause 5.1.

Where limits are stated using dBc, the reference l
37、evel is PX, measured at the antenna port according to clause 5.1. 5.3 Conducted RF immunity 5.3.1 Definition This is a measure of the capability of the receiver to receive a wanted modulated signal without exceeding a given degradation due to the presence of an unwanted input signal at any frequenci
38、es other than those of the spurious responses or the adjacent channels. This test is applicable to base station, mobile, portable and ancillary equipment. This test shall not apply to RF low-noise preamplifiers intended for location directly at the antenna. In normal use, amateur radio transmitting
39、equipment is not collocated with other radio transmitters operating within 10 % of its own carrier frequency, so that inter-transmitter intermodulation will not occur. Therefore immunity testing of the transmitter antenna port is not justified and is not included in the present document. 5.3.2 Metho
40、d of measurement 5.3.2.1 Method of measurement (analogue) The measurement procedure shall be as follows: Two signal generators, A and B, shall be connected to the receiver via a combining network (see clause 4.9): - Signal generator A shall be set to the nominal frequency of the receiver, with norma
41、l test modulation, (see table 1) and shall be applied to the receiver input connector via one input of the combining network at 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 d
42、ocumentation. - Signal generator B shall provide the unwanted signal as specified by table 8 and shall be applied to the receiver input connector via one input of the combining network. The test shall be performed over the frequency range 150 kHz to 1 GHz using stepped increments of maximum 1 % of t
43、he momentary frequency with the exception of the exclusion band. The exclusion band for a receiver and the receiver of a transceiver is determined by the characteristics of the equipment. In the case of receivers operating on a fixed single frequency, the exclusion band extends from -5 % to +5 % of
44、the fixed single frequency. In the case of 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 nar
45、row operating frequency band to +5 % of the highest frequency of that band. In the case of 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 signal test frequencies shall extend from -5 % to +5 % of each
46、 wanted signal test frequency. The test shall be applied to the receiver input connector via the second input of the combining network. Discrete spurious responses shall be ignored. ETSI ETSI EN 301 783-1 V1.2.1 (2010-07) 155.3.2.2 Method of measurement (digital) For digital equipment that supports
47、adaptive rates, testing is only required at the maximum bit rate that the manufacturer declares is compliant to the present document. The measurement procedure shall be as follows: Two signal generators, A and B, shall be connected to the receiver via a combining network (see clause 4.9): - Signal g
48、enerator A shall be set to the nominal frequency of the receiver, with normal test modulation, (see table 1) and shall be applied to the receiver input connector via one input of the combining network at a nominal value of 60 dB (or a lower value as declared by the manufacturer) above the maximum us
49、able sensitivity of the EUT as declared by the manufacturer in the product documentation. - Signal generator B shall provide the unwanted signal as specified by table 8 and shall be applied to the receiver input connector via one input of the combining network. The test shall be performed over the frequency range 150 kHz to 1 GHz using stepped increments of maximum 1 % of the momentary frequency with the exception of the exclusion band. The exclusion band for a receiver and the receiver of a transceiver is determined by the characteristics of the equipment. I
