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 equipment, 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.
Description
Variable attenuator SeriesLineup
High-Speed Programmable Attenuator MAT800
Multi-function programmable attenuator which can switch the attenuation by ultra high-speed (2μs). Maximum attenuation 80dB.
High-Speed Programmable Attenuator MAT810
Multi-function programmable attenuator whose switching speed is 2μs.
Step Attenuator MAT850
A compact and lightweight step attenuator in which the attenuation can be changed confirming the value by LED display.
Handover tester MH3800
Total system that can easily perform handover (handoff) evaluation of wireless communication equipment and actual operation test of “fallback (reduction of transmission speed)” due to distance attenuation in actual environment.
