1 Scope
The present document describes the technical characteristics and methods of testing the improved receiver performance
for professional mobile stations (professional MS), for the Pan European digital cellular communications system and
Personal Communication Systems (PCS) operating in the 900 MHz band (GSM 900), standardized by ETSI Special
Mobile Group (SMG).
The present document is valid for professional MS implemented according Phase 2+ R99.
The present document covers the requirements for testing the improved GSM-R receiver in order to provide sufficient
performance for mobile equipment.
It does not necessarily include all the characteristics which may be required by a user or subscriber, nor does it
necessarily represent the optimum performance achievable.
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 related 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, reference should be 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 includes the hardware to establish a connection across the radio
interface.

3 Abbreviations
For the purposes of the present document, the abbreviations given in TR 101 748 [i.1] apply.
4 Receiver
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 professional 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 without 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 different 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 requirements and this test apply to professional MS supporting speech.
For tests using ARFCN ranges the following table shall be used.
Table 1: ARFCN Ranges
Term
Band Low ARFCN range Mid ARFCN range High ARFCN range
E-GSM 900 975 to 980 60 to 65 120 to 124
R-GSM 900 955 to 960 (R-GSM) and 60 to 65 120 to 124

4.2 Blocking with CW interfering Signals
4.2.1 Blocking and spurious response - speech channels
4.2.1.1 Definition and applicability
Blocking is a measure of the ability 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 speech.
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 TS 102 933-1 [3], clause 6.1.
The reference sensitivity performance as specified in table 1 of TS 100 910 [2] shall be met when the
following signals are simultaneously input to the receiver:
- a useful signal at frequency f , as specified in TS 102 933-1 [3], clause 6.1.1;
0
- a continuous, static sine wave signal at a level as in the table 6 of TS 102 933-1 [3], clause 6.1.1 and at a
frequency (f) which 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 (which if below f and grouped shall not exceed
0
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
-113 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 possible out-of-band frequencies are tested as this results in excessive test time. However,
the total number of out-of-band spurious responses, specified in TS 102 933-1 [3], clause 6.1.1, are
allowed to ensure a fair test of the professional MS.
4.2.1.4 Method of test
4.2.1.4.1 Initial conditions
A call is set up according to the generic call set up procedure, except the BCCH frequency list shall be empty, on a TCH
with an arbitrary ARFCN in the range supported by the professional MS. The power control level is set to maximum
power.
The SS transmits Standard Test Signal C1 on the traffic channel (TCH frequency FR).

The SS commands the professional MS to create traffic channel loop back signalling erased frames.
4.2.1.4.2 Procedure
a) The SS produces a static wanted signal and a static interfering signal at the same time. The amplitude of the
wanted signal is set to -100 dBm.
b) The unwanted signal is a C.W. signal (Standard test signal IO) of frequency FB. It is applied in turn on the
subset of frequencies calculated in step c) in the overall range 100 kHz to 12,75 GHz, where FB is an integer
multiple of 200 kHz.
However, frequencies in the range FR ± 600 kHz are excluded.
NOTE 1: As specified by EN 300 607-1 (V8.1.1) [i.2], clause 14.7: "Allowance must be made for possible spurious
signals arising from the SS. These are particularly likely at sub harmonic frequencies nFB where n = 2, 3,
4, 5, etc.".
c) The frequenci
