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 reproducibility of test results.

The development of wireless communication devices such as smartphones (mobile devices) and functional evaluation tests at the time of shipment greatly benefit from the use of electrical attenuators for assessing communication characteristics based on distance attenuation. Our high-speed programmable attenuator MAT series does not produce spike noise during attenuation level switching, allowing for uninterrupted virtualization of the mobile terminal's actual movement. By adopting a programmable attenuator, it is also possible to control it externally via GPIB or similar interfaces. This is particularly effective for creating unmanned testing environments and can be utilized for long-duration durability tests. Additionally, when installing wireless devices inside a radio anechoic chamber, they can be secured with specially developed fixtures for that specific test. By fixing the distance between the transmitting antenna and the receiving terminal, we achieve uniformity in the measurement environment, thereby 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 materials or feel free to contact us.
