Product Description

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.

Description:
MAT810 a maximum attenuation 60dB. Multi-function programmable attenuator which can switch the attenuation of microwave signal by ultra high-speed (2μs).

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.

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.

Features:
1. The frequency range is so wide as 300MHz to 6.6GHz.
2. The minimum step size of attenuation is 0.05dB, and the maximum attenuation is 60dB.
3. Other features are the same as MAT800.

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.

transmission-characteristics-test

  • The bidirectional communication between the wireless simulator and the terminal unit put in the anechoic box is performed through TX/RX antenna installed in the box.
  • Each protocool test (layer one to three) is done by using the simulator.
  • Handover test and fallback test is available too.
