basic information

Wireless terminal and module wireless system evaluation (Low Power wireless such as ZigBee) By isolating the wireless terminal and module from unwanted radio waves in the surrounding environment and creating a radio wave anechoic environment, it becomes possible to evaluate the wireless system of the evaluation terminal. ■□■ Solution ■□■ ■ Transmission characteristic testing via air connection - The radio waves emitted from the wireless module installed on a turntable are received by a receiving antenna mounted at the opposite position and output outside the radio wave anechoic chamber. - By connecting measurement instruments such as a spectrum analyzer, evaluation of each test item for the transmission characteristics of the wireless module can be conducted. ■ Reception characteristic testing via air connection - Signals from the wireless terminal are transmitted from the transmitting antenna through a programmable attenuator, and the baseband signal extracted from the wireless module is measured. - By connecting measurement instruments such as a BER (Bit Error Rate) meter, spectrum analyzer, or power meter, measurements of reception sensitivity and reception level can be conducted. ■ For more details, please download the catalog or contact us.
