What is a variable attenuator?
- The best equipment for simulating the change of the radio wave in the air.
- These attenuators can switch the attenuation of the microwave signal.
- It corresponds to various tests and simulations.
Optimum for simulation of wireless communication equipments, such as handover test, dynamic motion test and receiving sensitivity test. Moreover, optimum for the simulation of the receiving trouble by the rainfall attenuation in BS/CS digital broadcasting.
All models of the MAT series are electronic attenuators.
Therefore, the various tests and simulations can be done in an ideal environment in which there are no chattering and spike at the switching moment.
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.
Step Attenuator MAT850
Covers the wideband (300MHz to 6.1GHz) in spite of small size, lightweight and low cost.
Putting upward or on transverse is available.
The attenuation value is easy to see bacause of the large seven segments LED.
The three knobs are independent in every 10dB, 1dB and 0.1dB.
And neither chattering nor spike are generated when switching the knobs.
Handover Tester MH3800
For improving the efficiency of verification man-hours by quantifying the test environment, long-run (aging) tests, and automating tests.
