Test Procedure Used KDB 558074 D01 v05r02 - Section 8.5 & Section 8.6 ANSI C63.10 – Section 11.11&11.12 7.5.3. Test Setting Reference level measurement: Establish a reference level by using the following procedure: (a) Set instrument center frequency to DTS channel center frequency. (b) Set the span to ≥ 1.5 times the DTS bandwidth. (c) Set the RBW = 100 kHz. (d) Set the VBW ≥ [3 × RBW]. (e) Detector = peak. (f) Sweep time = No faster than coupled (auto) time. (g) Trace mode = max-hold. (h) Allow trace to fully stabilize. (i) Use the peak marker function to determine the maximum PSD level. Emission level measurement: Establish an emission level by using the following procedure: (a) Set the center frequency and span to encompass frequency range to be measured. Note that the frequency range might need to be divided into multiple frequency ranges to retain frequency resolution. Report No.: S20250916065901 Page Number: 32 of 70 NOTE—the number of points can also be increased for large spans to retain frequency resolution (b) Set the RBW = 100 kHz. (c) Set the VBW ≥ [3 × RBW]. (d) Detector = peak. (e) Sweep time = No faster than coupled (auto) time. (f) Trace mode = max-hold. (g) Allow trace to fully stabilize. (h) Use the peak marker function to determine the maximum amplitude level. Ensure that the amplitude of all unwanted emissions outside of the authorized frequency band (excluding restricted frequency bands) is attenuated by at least the minimum requirements specified in 11.11. Report the three highest emissions relative to the limit. 7.5.4. Test Setup Report No.: S20250916065901 Page Number: 33 of 70 7.5.5.
