2026-06-25 Receiver Sensitivity Test Records for Micro-Nano Satellite Inter-Satellite Communication Payload doi:10.57760/sciencedb.space.03695 en This dataset comprises the raw records and processed results of ground-based receiver sensitivity tests for a micro-nano satellite inter-satellite communication payload. The tests were conducted on February 26, 2024, in the anechoic chamber of the National Space Science Center. The test system consisted of a transponder ground test equipment (Ruixinfeng, 1 set), a power meter E4413A (Keysight, 1 set), a variable attenuator (Keysight, 1 set), a spectrum analyzer (Rohde & Schwarz, 1 set), and the communication payload prototype under test. During the testing process, the transponder ground test equipment generated preset test signals, while the variable attenuator gradually increased the link attenuation. Meanwhile, the power meter E4413A recorded the received signal power in real time, and the spectrum analyzer monitored signal quality. Each attenuation step was maintained for a certain duration, with multiple measurements taken and averaged. When the received signal power dropped to a level at which the payload under test could no longer correctly demodulate the signal, the corresponding received power, calibrated by the power meter, was recorded as the sensitivity threshold. receive sensitivity; sensitivity; test; record Liu Cairui Liang Xianfeng Xue Sheng PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
