The AIE-W5LR from Becker Nachrichtentechnik is an Air Interface Emulator that operates from 500 to 9000 MHz. It enables realistic emulation of HF levels with its 5 bi-directional input/output RF ports that can be connected to different network access points. Each of the 5 ports can be fed separately with a composite RF signal and the freely programmable mixture of the other 4 signals can then be set individually for each port. The signal levels can be varied over a wide dynamic range using internal precision attenuators which makes it possible to emulate a realistic air interface in which connected access points simultaneously receive field signals of different strengths from other access points in the network.
The AIE-W5LR can also be used as a non-blocking matrix switch and its attenuators between the signal paths also allow the emulation of fading effects. 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 with N-type (female) connectors and is ideal for air interface emulation, Wi-Fi communication testing, 802.11 a/h/ac/g/n/p, V2X & V2V, fading simulation, automatic test systems and laboratory test applications.
