Optimal configuration to simulate the change of radio wave in air.
lead to quantifying the test environment, long run (aging) test and reduction of the verification time by automating the test.
Enable 8 paths as standard and maximum 64 paths (controls 64 units of MAT 800/810 at once).

Features

It simulates the attenuation process of radio wave in which the communication of mobile terminal transfers from base station A to base station B.

*Since MH3800 only simulates the communication environment, the evaluation of actual communication quality such as throughput measurement and packet capture needs an evaluation software such as iperf and Wireshark.

Handover (handoff) evaluation

The strength of the radio wave when the mobile terminal moves closer or farther towards multiple base stations or access points can be simulated, and then the handover is caused.

The attenuation scenario can be synchronously controlled up to 64 channels.

Fallback operation test (decrease in transmission speed)

The attenuation amount according to the distance to the cell can be switched continuously and without 1/4 interruption.

The high-speed programmable attenuator MAT 800/810 is an electronic variable attenuator and has a very fast switching speed of 2 μs. Therefore it can simulate the transient phenomena such as shadowing.

Long-run (aging) test

By automating the repetitive tests in the same scenario, the efficiency and time of test will be improved.

A continuous durability test in day and night can be also done by uninhabited.

High versatile and scalable system

If it is used within the frequency range from 300 MHz to 12.5 GHz, there is no need to worry about communication standards. The equipment doesn’t become obsolete, and also is excellent in versatility and scalability.

*The frequency range depends on which of the six models of MAT 800 A / B / C / D / E and MAT 810 is used.

Simple scenario creation and control

The attenuation data creation & control software MAS 801 enables to create and control scenarios with intuitive operation.

Moreover, the attenuation data during executing scenario can be monitored.

Target market

Products lineup

High-Speed Programmable Attenuator MAT800 Series

Multi-function programmable attenuator which can switch the attenuation by ultra high-speed (2μs). Maximum attenuation 80dB.

High-Speed Programmable Attenuator MAT810

There are no chattering and spike at switching moment because of differing from traditional mechanical attenuator. The precise simulation of wireless communication is capable by setting the attenuation step small. The frequency band is divided into sixteen and the calibration is done at each frequency so that the frequency characteristics of attenuation is made flat.
