[Application Example] Reception Sensitivity Testing of Wireless Communication Devices Using an Anechoic Chamber
【Product Introduction】 ■ Radio Wave Dark Box / Shield Box Low price, lightweight, short delivery time! High quality, reliability, and excellent cost performance radio wave dark boxes and shield boxes provided by a measurement instrument manufacturer. ■ Programmable Attenuator Capable of supporting various tests and simulations in an ideal environment without chattering or spikes. ■ Step Attenuator MAT850 Manual adjustment in 0.1dB increments while checking the current attenuation level. Many modern wireless communication devices are designed with lower reception sensitivity to receive signals from further away. Additionally, small wireless communication devices, including IoT devices, often have antennas mounted on the circuit board and may not have RF connectors. When conducting reception sensitivity tests under such conditions, excessive surrounding noise can bury the desired signals in noise, making it impossible to accurately measure reception sensitivity. To measure reception sensitivity more accurately, we recommend using a radio wave dark box that can create a low-noise environment.

basic information
Many of today's wireless communication devices are designed with low reception sensitivity to receive signals from farther away. Additionally, small wireless communication devices, such as IoT devices, often have antennas mounted on the circuit board and may not have RF connectors. When conducting reception sensitivity tests under these conditions, if there is a lot of surrounding noise, the desired signals can become buried in the noise, making it impossible to accurately measure reception sensitivity. To measure reception sensitivity more accurately, it is recommended to use a radio frequency anechoic chamber that can create a low-noise environment.
