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.
