eubus MAM4 Manual Attenuator Module

Product Description

The MAM 4 has between 4 and 36 high-precision attenuators and 4 up to 36 inputs and outputs that permit complex radio hop simulation such as it is required for handover test scenarios, for example.

The MAM 4 is a low cost manual version of the remotely controlled NAM 4 and can be easily operated by multifunctional knobs. Except the network function, all other features of the NAM 4 are included in manual system as well. The smallest standard version of the MAM 4, the MAM 4-4, has 4 channels with 4 solid state programmable attenuators which operates in a frequency range between 380MHz – 3 GHz (0…95,5dB, 0,5dB steps) or 700MHz-6GHz (0…63dB, 1dB steps). All kind of complexities are available upon request, even beyond the standard MAM 4-36.

For each channel an attenuation offset can be set and everlasting stored.
