Evaluation of Wireless IP Transmission and Communication Characteristics of Client Terminal Devices

[Application Example] Preventing interference from surrounding noise, virtualizing communication characteristic evaluation, and stabilizing the measurement environment to ensure the reproducibility of test results.

The development of wireless communication devices such as smartphones (mobile devices) and functional evaluation tests at the time of shipment make electric attenuators very effective for evaluating communication characteristics based on transmission and reception levels affected by distance attenuation. Our high-speed programmable attenuator MAT series does not produce spike noise during attenuation level switching and can virtualize the actual movement of mobile terminals without interruption. By adopting a programmable attenuator, it is also possible to control it externally via GPIB or similar interfaces. These are particularly effective for creating unmanned testing environments and can be utilized for long-duration endurance tests. Additionally, when installing wireless devices inside a radio anechoic chamber, they are fixed using specially developed fixtures for the specific tests. By fixing the distance between the transmitting antenna and the receiving terminal, uniformity in the measurement environment is achieved, improving the reproducibility of test results. 【Product Introduction】 ■ Radio Anechoic Chamber Taurus Series MY1520 ■ I/F Module ■ High-Speed Programmable Attenuator MAT800 Series ■ Portable Antenna M301–M309 *For more details, please refer to the PDF document or feel free to contact us.
