| Unless otherwise stated, the operating band unwanted emission (OBUE) limits in FR1 are defined from 10 MHz below the lowest frequency of each supported uplink operating band up to 10 MHz above the highest frequency of each supported uplink operating band. Basic limits are specified in the tables below, where:
- f is the separation between the assigned transmission frequency and the nominal -3dB point of the measuring filter closest to the carrier frequency.
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 8.4.2.2 Minimum requirement
| The minimum requirement applies the connector supporting transmission in the operating band.
The minimum requirement for CW node is defined in TS 38.194 [3], clause 8.5.3.2.
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 8.4.2.3 Test purpose

| |
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 8.4.2.4.1 Initial conditions
| Test environment: Normal; see [annex B.2].
RF frequency point to be tested for single-tone signal: B, M and T; see clause [4.7].
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 8.4.2.4.2 Procedure
| 1) Connect the connector under test to measurement equipment as shown in [annex D.1.1] for CW node.
As a general rule, the resolution bandwidth of the measuring equipment should be equal to the measurement bandwidth. However, to improve measurement accuracy, sensitivity, efficiency and avoiding e.g. carrier leakage, the resolution bandwidth may be smaller than the measurement bandwidth. When the resolution bandwidth is smaller than the measurement bandwidth, the result should be integrated over the measurement bandwidth in order to obtain the equivalent noise bandwidth of the measurement bandwidth.
The measurement device characteristics shall be:
- Detection mode: True RMS.
The emission power should be averaged over an appropriate time duration to ensure the measurement is within the measurement uncertainty in [Table 4.1.2.2-1].
2) For a connector declared to be capable of single-tone operation only, set the representative connector under test to transmit according to the applicable test configuration in clause [4.5] at output power Prated for CW node. Test signal set-up shall be according to [TBD].
3) Step the centre frequency of the measurement filter in contiguous steps and measure the emission within the specified frequency ranges with the specified measurement bandwidth.
4) Repeat the test for the remaining test cases, with the test signal set-up according to [TBD].

a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.1.1 General
| Unless otherwise stated, the transmitter characteristics in clause 6 are specified at the BS antenna connector (test port A) with a full complement of transceivers for the configuration in normal operating conditions. If any external apparatus such as a TX amplifier, a filter or the combination of such devices is used, requirements apply at the far end antenna connector (test port B).

a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.1.2 Transmission with multiple transmitter antenna connectors
| Unless otherwise stated, for the tests in clause 6 of the present document, the requirement applies for each transmitter antenna connector in the case of transmission with multiple transmitter antenna connectors.
Transmitter requirements are tested at the antenna connector, with the remaining antenna connector(s) being terminated. If the manufacturer has declared the transmitter paths to be equivalent (D.32), it is sufficient to measure the signal at any one of the transmitter antenna connectors.

a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.2.1 General
| Unless otherwise stated, the receiver characteristics in clause 7 are specified at the BS antenna connector (test port A) with a full complement of transceivers for the configuration in normal operating conditions. If any external apparatus such as a RX amplifier, a filter or the combination of such devices is used, requirements apply at the far end antenna connector (test port B).

a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.2.2 Reception with multiple receiver antenna connectors, receiver diversity
| For the tests in clause 7 of the present document, the requirement applies at each receiver antenna connector for receivers with antenna diversity or in the case of multi-carrier reception with multiple receiver antenna connectors.
Receiver requirements are tested at the antenna connector, with the remaining receiver(s) disabled or their antenna connector(s) being terminated. If the manufacturer has declared the receiver paths to be equivalent (D.32), it is sufficient to apply the specified test signal at any one of the receiver antenna connectors.
For a BS type 1-C supporting multi-band operation, multi-band tests for ACS, blocking and intermodulation are performed with the interferer(s) applied to each antenna connector mapped to the receiver for the wanted signal(s), however only to one antenna connector at a time. Antenna connectors to which no signals are applied are terminated.
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.3 Duplexers
| The requirements of the present document shall be met with a duplexer fitted, if a duplexer is supplied as part of the BS. If the duplexer is supplied as an option by the manufacturer, sufficient tests should be repeated with and without the duplexer fitted to verify that the BS meets the requirements of the present document in both cases.
The following tests shall be performed with the duplexer fitted, and without it fitted if this is an option:
1) clause 6.2, base station output power, for the highest static power step only, if this is measured at the antenna connector;
2) clause 6.6, unwanted emissions; outside the BS transmit band;
3) clause 6.6.5.5.1.2, protection of the BS receiver;
4) clause 6.7, transmit intermodulation; for the testing of conformance, the carrier frequencies should be selected to minimize intermodulation products from the transmitters falling in receive channels.
The remaining tests may be performed with or without the duplexer fitted.
NOTE 1: When performing receiver tests with a duplexer fitted, it is important to ensure that the output from the transmitters does not affect the test apparatus. This can be achieved using a combination of attenuators, isolators and filters.
NOTE 2: When duplexers are used, intermodulation products will be generated, not only in the duplexer but also in the antenna system. The intermodulation products generated in the antenna system are not controlled by 3GPP specifications, and may degrade during operation (e.g. due to moisture ingress). Therefore, to ensure continued satisfactory operation of a BS, an operator will normally select NR-ARFCNs to minimize intermodulation products falling on receive channels. For testing of complete conformance, an operator may specify the NR-ARFCNs to be used.
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.4 Power supply options
| If the BS is supplied with a number of different power supply configurations, it may not be necessary to test RF parameters for each of the power supply options, provided that it can be demonstrated that the range of conditions over which the equipment is tested is at least as great as the range of conditions due to any of the power supply configurations.
This applies particularly if a BS contains a DC rail which can be supplied either externally or from an internal mains power supply. In this case, the conditions of extreme power supply for the mains power supply options can be tested by testing only the external DC supply option. The range of DC input voltages for the test should be sufficient to verify the performance with any of the power supplies, over its range of operating conditions within the BS, including variation of mains input voltage, temperature and output current.
|
a1d9979ec3fb8c2091ddd4425cd961c2 | 38.195 | 4.53.1.5 Ancillary RF amplifiers
| The BS type 1-C requirements of the present document shall be met with the ancillary RF amplifier fitted. At tests according to clauses 6 and 7 for TX and RX respectively, the ancillary amplifier is connected to the BS by a connecting network (including any cable(s), attenuator(s), etc.) with applicable loss to make sure the appropriate operating conditions of the ancillary amplifier and the BS. The applicable connecting network loss range is declared by the manufacturer (D.35). Other characteristics and the temperature dependence of the attenuation of the connecting network are neglected. The actual attenuation value of the connecting network is chosen for each test as one of the applicable extreme values. The lowest value is used unless otherwise stated.
Sufficient tests should be repeated with the ancillary amplifier fitted and, if it is optional, without the ancillary RF amplifier to verify that the BS meets the requirements of the present document in both cases.
When testing, the following tests shall be repeated with the optional ancillary amplifier fitted according to the table below, where "x" denotes that the test is applicable:

NOTE 1: Combining can be by duplex filters or any other network. The amplifiers can either be in RX or TX branch or in both. Either one of these amplifiers could be a passive network.
NOTE 2: Unless otherwise stated, BS with both TX and RX amplifiers are tested once with both amplifiers active for each test.
In base station output power test (clause 6.2) and reference sensitivity level test (clause 7.2) highest applicable attenuation value is applied.
