HYTEM Attenuation Matrix
Frequency Range: 600 MHz - 6 GHz
Attenuation matrixes allow to send one or multiple signals to one or multiple outputs, while changing power level of each signal individually. Different from handover simulation, fast fading requires very fast attenuation change speed. In handover simulation subracks, orders are executed on a PC, then transmitted to subrack (through Ethernet or USB), which will add latency.
To allow faster speeds, attenuation matrixes integrate an embedded industrial PC, from which scenarios are run. Attenuation variation speed of 25 μsec can be achieved (against 25 to 50 msec for handover simulation subracks).
