[0071] Preferably, the signal generator includes two 5G analog signal interference sources.

[0072] Preferably, the simulated base station is a 5G integrated tester.

[0073] like Figure 3-a As shown, this embodiment also provides a 5G NR supplementary frequency band testing method, which includes the following steps:

[0074] S301a. Determine the frequency range of the supplementary uplink frequency band signal based on the 5G NR band carrier signal.

[0075] In this step, the NUL end is a terminal port connected to the first power divider. One end of the first power divider is connected to the SS, and the other end is connected to the SA via K1. The SS is configured with the carrier frequency band to be aggregated, and the SA analyzes the signal waveform of the 5G carrier aggregation. The SUL end is connected to the SS via the second power divider, and then connected to the SA via the other end of K1. In this bidirectional connection, the frequency range of the supplementary uplink frequency band is determined to be 710MHz-2.4GHz.

[0076] S302a. Measure clutter signals based on supplementary uplink frequency band signals and 5G NR frequency band carrier signals.

[0077] In this step, the NUL and SUL under test are emitted simultaneously, and some of the measurement signals are intermodulated in the SA. When the two signals are complementary, the clutter signal is measured separately. The other two signals and the useful signal enter the SS at the same time for signal data analysis. Among them, some of the measurement signals are the dominant uplink signal; the two signals are NUL and SUL, and the other two are downlink signals.

[0080] In this step, the SDL and NUL downlink carrier aggregation signals are used to supplement the signal and are connected to the SA via K1 to determine the downlink supplementary frequency band with a frequency range of 1427MHz-1517MHz.

[0081] S302b: Demodulate the signal synthesized from the interference source signal and the supplementary downlink frequency band signal to obtain the first sensitivity.

[0083] In S302b and S303b, the two SG signals are reverse-connected to the SDL signal via K2, so that the two interference signals with the same frequency and path are connected to the downlink supplementary frequency band. Then, the combined signal of SDL and SG is reverse-connected to SS through the corresponding power divider to interpret the demodulation of the downlink signal and obtain the first sensitivity. Then, the SG is turned off to read the second sensitivity in SS.

[0084] S304b: Test the supplementary downlink frequency band signal based on the first sensitivity and the second sensitivity.

[0085] In this step, the two sets of data are compared to calculate the difference in sensitivity, thus completing the test of the supplementary downlink frequency band signal.
