The best equipment for simulating the change of the radio wave in the air. These attenuators can switch the attenuation of the microwave signal. 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.
MAT800/MAT810 is a multi-functional and authentic programmable attenuator that is capable of controlling the attenuation at ultra-high speed. MAT850 is a small and lightweight step attenuator that can adjust the attenuation in 0.1dB by hand watching LED display.
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.
Description:
MAT 850 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.
Features:
The frequency range is so wide as 300MHz to 6.1GHz.
The minimum step size of attenuation is 0.1dB, and the maximum attenuation is 60dB.
Equips with spike noise removal circuit at switching moment.
LED display easy to see.

Software for making attenuation program /Application
1. Software for making attenuation program MAS800 (Standard accessory)
Waveform creation – The nine types of standard waveforms are prepared like sine wave and triangle wave. A waveform is created by straight line input, arithmetic calculation input(addition, subtraction, clipping, offset and etc), one-point input and freehand line input by a mouse.
Waveform editing and file management – Waveform editing and file management may be performed using CUT, COPY, PASTE and UNDO.
