[Application Example] OTA Testing Solution in IoT (Throughput Testing)

Our company provides a system that combines electronic programmable attenuators and shielded boxes as an OTA testing solution compatible with various wireless communication standards, including WiFi, Bluetooth, and cellular. As IoT devices (things) diversify, OTA (Over the Air) testing is necessary for evaluating wireless performance. In OTA testing, these "things" connect wirelessly, requiring a radio-frequency independent space (shielded environment) that does not affect the existing wireless environment and is not influenced by it. 【Solution】 ■ Example test items: 1-to-1 throughput testing system - Throughput - Device interoperability - Noise resistance - Directional characteristics *For more details, please refer to the PDF document or feel free to contact us. 【System Configuration】 ■ Programmable attenuator ■ Shielded box ■ Attenuation data creation and control software & trigger box ■ Various antennas ■ Various cables *For more details, please refer to the PDF document or feel free to contact us.

【Technical Data】High-Speed Programmable Attenuator MAT800/MAT810

■High-Speed Programmable Attenuator MAT800 Series Maximum attenuation of 80dB. A multifunctional, fully-fledged programmable feature that allows for ultra-fast control of attenuation levels. ■High-Speed Programmable Attenuator MAT810 Maximum attenuation of 60dB. A multifunctional, fully-fledged programmable feature that allows for ultra-fast control of attenuation levels. *For more details, please refer to the PDF document or feel free to contact us. The MAT800/810 has certain frequency characteristics. The attenuation level changes with frequency, creating a gentle curve overall. Therefore, for the corresponding 16 frequency ranges, the MAT800 has 1600 steps of attenuation calibrated using an SG and power meter, while the MAT810 has 1200 steps of attenuation calibrated in the same manner. The MAT800 allows for attenuation settings from 0dB to 80dB in 0.05dB increments with 1600 steps, while the MAT810 allows for attenuation settings from 0dB to 60dB in 0.05dB increments with 1200 steps.

Programmable Attenuator ATT-01/10

Programmable Attenuator ATT-01/10

A programmable resistor attenuator that can control attenuation with 4 bits!

The characteristic impedance is 600Ω. A programmable resistive attenuator that can control the attenuation amount with 4 bits. 【Features】 ○ Attenuation control can be performed at TTL or C-MOS levels. ○ The signal circuit and control circuit are electrically isolated. ○ ATT-01 consists of an unbalanced π-type resistive attenuator (pad) with 1, 2, 4, and 8 dB, allowing for a range of 0 to 15 dB (set with hexadecimal data) in 1 dB steps. ATT-10 consists of pads with 10, 20, 40, and 40 dB, capable of attenuating up to 110 dB. ● For other functions and details, please download the catalog.

[Application Example] OTA Testing Solution in IoT - Throughput Testing -

The era of the Internet of Things (IoT), where various "things" are connected to a network, has arrived, and many electronic devices, machines, and other "things" are connected to the network using wireless communication. As IoT devices (things) diversify, OTA (Over the Air) testing is necessary for evaluating wireless performance. In OTA testing, these "things" must connect wirelessly in a space that is electromagnetically independent, meaning it does not affect the existing wireless environment and is not affected by it (shielded environment). Our company offers a system that combines electronic programmable attenuators and shielded boxes as an OTA testing solution compatible with various wireless communication standards, including WiFi, Bluetooth, and cellular. 【Product Introduction】 ■ Programmable Attenuator ■ Shielded Box 【System Configuration】 ■ Programmable Attenuator ■ Shielded Box ■ Attenuation Data Creation and Control Software & Trigger Box ■ Various Antennas ■ Various Cables ● For more details, please download the catalog or contact us.

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

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.
