Light Attenuator OVA-100 | High Precision Attenuation Control - Maximum 100dB

Light Attenuator OVA-100 | High Precision Attenuation Control - Maximum 100dB

High-precision control of optical power. Up to 100dB optical attenuator compatible with BERT testing and WDM evaluation.

The OVA-100 is an optical attenuator characterized by high precision and excellent reproducibility, available in benchtop or rack-mounted configurations. It can be utilized for adjusting optical output levels in automatic test systems, from research and development to mass production testing, such as bit error rate testing (BERT) for transceivers and variation compensation for each wavelength channel in WDM systems. It achieves high reproducibility of ±0.01 dB and a wide dynamic range of up to 100 dB. Operation is supported via a touch screen on the front panel or remote control through USB and Ethernet. The OVA series attenuators operate in the wavelength range of 1200 to 1700 nm for single mode and 750 to 1700 nm for multi-mode. Additionally, by adding a photodiode (PD) for power monitoring, it can automatically adjust to the set power level while monitoring output power, thereby establishing a stable testing environment.

[Application Example] OTA Testing Solutions in IoT

[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.
