Abstract:

Based on the LabVIEW virtual instrument development platform, a set of multi-parameter automatic measurement system was designed for 28GHz millimeter wave wireless channel, and the temperature and humidity pressure sensing module was added to the system. The hardware system adopts vector signal generator E8267D and and signal analyzer N9010A of the Keysight, through GPIB to USB cable connected to the notebook computer, then LabVIEW programming the Standard command of language SCPI to control the instruments, and realize the system automatic measurement. The actual measurement results show that the system is in good operation with high sensitivity, and it automatically obtains the temperature and humidity pressure data of the measured channel environment, displays the waveform curve in real time, and automatically stores the datas. The system realizes the real-time monitoring of the wireless channel environment and the big data statistics of the channel characteristics, and has good practical application value.
