The present document is part of the GSM-series of technical specifications. The present document neither replaces any of the other GSM technical specifications or GSM rela
27、ted ETSs or ENs, nor is it created to provide full understanding of (or parts of) the GSM 900 system. The present document lists the additional test procedures, and provides the methods of test for testing a professional MS for conformance to the GSM standard. For a full description of the system, r
28、eference are made to all the GSM technical specifications or GSM related ETSs or ENs. Clause 2 provides a complete list of the GSM technical specifications, GSM related ETSs, ENs, and ETRs, on which this conformance test specifications is based. The present document applies to the unit which include
29、s the hardware to establish a connection across the radio interface. 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.

38、 8 Watt mobiles 4.0 General In this clause receiver measurements are described, for professional mobile stations equipped with a permanent antenna connector only. Wherever in this clause, for FACCH tests, the SS is required to send a Layer 3 message not requiring a Layer 3 response from the professi
39、onal MS the message can be a TEST INTERFACE message or a STATUS message, possibly with an unknown Protocol Discriminator. Testing philosophy Certain assumptions concerning the functional mechanisms of GSM receivers have been made in order to define tests that will verify the receiver performance wit
40、hout excessive redundancy and excessive test times. The receiver functions can be divided into: Analogue RF and IF stages that are affected by input levels, temperature and power supply levels. Demodulator that is affected by input levels and interfering signals. Decoders that are affected by the di
41、fferent logical channels and input levels. The tests are designed to stress each of these blocks with a minimum of redundancy. 4.1 Reference sensitivity The reference sensitivity is the signal level at the professional MS receiver input at which a certain BER and FER shall be achieved. The requireme
42、nts and this test apply to professional MS supporting speech. For tests using ARFCN ranges values in the table 1 shall be used.

44、ty of the receiver to receive a modulated wanted input signal in the presence of an unwanted input signal, on frequencies other than those of the spurious responses or the adjacent channels, without exceeding a given degradation. The requirements and this test apply to professional MS supporting spe
45、ech. 4.2.1.2 Conformance requirement 1) The blocking characteristics of the receiver are specified separately for in-band and out-of-band performance and shall be as identified in ETSI TS 102 933-1 3, clause 7.1. The reference sensitivity performance as specified in table 1 of ETSI TS 100 910 2 shal
46、l be met when the following signals are simultaneously input to the receiver: - a useful signal at frequency f0, as specified in ETSI TS 102 933-1 3, clause 7.1.1; - a continuous, static sine wave signal at a level as in the table 10 of ETSI TS 102 933-1 3, clause 7.1.1 and at a frequency (f) which
47、is an integer multiple of 200 kHz; with the following exceptions, called spurious response frequencies: a) ER-GSM 900/R-GSM 900: in band, for a maximum of six occurrences (which if grouped shall not exceed three contiguous occurrences per group); b) out-of-band, for a maximum of 24 occurrences (whic
48、h if below f0and grouped shall not exceed three contiguous occurrences per group). Where the above performance shall be met when the continuous sine wave signal (f) is set to a level of -40 dBm. 2) Testing conditions shall guarantee that the noise level of their used interfering signals are below -1
49、13 dBm/200 kHz on the wanted ARFCN and its (bi) adjacent channels. 4.2.1.3 Test purpose 1) To verify that the in band blocking performance is met without exceeding the total number of allowed in band spurious responses. An allowance is made for the statistical significance of the test. 2) To verify that at selected out-of-band frequencies, the out-of-band blocking performance is met without exceeding the total number of allowed out-of-band spurious responses. An allowance is made for the statistical significance of the test. NOTE: Not all of the po
