A.4 Test Setup A4.1 The test below is considered for the Spectral Mask test. Figures 1 and 2 show examples of BS/MS testing setup. Figure 1. BS test Figure 2. MS test setup A.4.2 Test Procedure A4.2.1 Initialization: Set up the test environment for the UUT. Configure the spectrum analyzer in accordance with Table 1. Note. Although the resolution bandwidth (RBW) is set to 100 kHz, the RBW can be set to 10 kHz or a smaller value than 100 kHz to improve measurement accuracy for a narrow region where the variation of the power is large, such as a) range defined in Paragraph 3.
