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 light eight 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.

1. Five models are prepared corresponding to each frequency band.

2. The minimum step size of attenuation is 0.05dB, and the maximum attenuation is 80dB.

3. There is no spike at switching moment, and it is, therefore, possible to test without causing communication fault.

4. GP-IB and RS-232C interface are equipped as standard accessories

5. It is posible to make the arbitrary attenuation program.

  - Manual mode or program mode is selectable.

  - The software for making attenuation program is a standard accessory

  - 128k words program memory is built-in.

  - 2?s maximum switching (readout) speed at program mode. And three readout modes of FREE?BURST?GATE .

  - Equips with External readout clock input, Trigger input and SYNC output in consideration of connecting with other systems.

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.

1. The frequency range is so wide as 300MHz to 6.1GHz.

2. The minimum step size of attenuation is 0.1dB, and the maximum attenuation is 60dB.

3. Equips with spike noise removal circuit at switching moment.

4. LED display easy to see.
