The AIE-4X4LR from Becker RF is a 4x4 Channel Air Interface Emulator that operates from 500 to 9000 MHz. It has 4 RF Ports for the base station, and four ports for DUTs like cellular phones, and all signal paths are bidirectional. Each of the 4 DUT ports can be fed with a composite RF signal composed of a programmable mix of the four signals coming from the base station ports. It has digitally controlled internal precision attenuators for varying signal levels. This air interface emulator enables accurate emulation of RF levels for radio communication between mobile devices and wireless networks. It can recreate a realistic air interface, whereby the DUTs receive multiple cellular stations simultaneously with varying propagation loss. In particular, it allows the simulation of handovers between cellular base stations and cellular phones.
The AIE-4X4LR can also be used as a non-blocking matrix with every output having free access to each input. The attenuators between the signal paths also allow the emulation of fading effects. With a fast attenuator response time, the device is an efficient and fast solution for automatic testing systems. It can be conveniently controlled remotely via LAN and USB interfaces and an additional TRIGGER-IO port. This emulator is available in a 19” 1U enclosure that measures 482 x 44 x 460 mm and has N-type (female) connectors. It is ideal for air interface emulation, cellular standards including 5G (FR1), Wi-Fi communication testing, 802.11 a/h/ac/g/n/p, V2X & V2V, fading simulation, automatic test systems, and laboratory test applications.
This air interface emulator requires an AC supply from 90 to 260 V and consumes 4 W of power.
