7.9F.4 Test Description
7.9F.4.1 Initial Conditions
Initial conditions are a set of test configurations the UE needs to be tested in and the steps for the SS to take with the UE to reach the correct measurement state.
The initial test configurations consist of environmental conditions and test frequencies based on the subset of E-UTRA operating bands defined for NB-IoT in clause 5.2F. All of these configurations shall be tested with applicable test parameters, and are shown in table 7.9F.4.1-1. The details of the downlink reference measurement channels (RMCs) are specified in Annex A.3.

1. Connect the SS to the UE antenna connector as shown in TS 36.508 [7] Annex A, Figure A.8 using only the main UE Tx/Rx antenna.
2. The parameter settings for the cell are set up according to TS 36.508 [7] subclause 8.1.4.3
3. Downlink signals are initially set up according to Annex C.0, C.1 and C.2,
4. The DL Reference Measurement channel is set according to Table 7.9F.4.1-1.
5. Propagation conditions are set according to Annex B.0.
6. Ensure the UE is in State 2A-NB with CP CIoT Optimisation according to TS 36.508 [7] clause 8.1.5. Message contents are defined in clause 7.9F.4.3.
7.9F.4.2 Test Procedure
1. Sweep the spectrum analyzer (or equivalent equipment) over a frequency range and measure the average power of spurious emission.
7.9F.4.3 Message Contents
Message contents are according to TS 36.508 [7] subclause 8.1.6.
7.9F.5 Test Requirement
The measured spurious emissions derived in step 1), shall not exceed the maximum level specified in Table 7.9F.5-1
