AIE-W5LR

5-port radio field simulation, 500 to 9000 MHz

The radio field simulation AIE-W5LR enables the realistic emulation of HF levels for radio field communication such as in wireless networks. The device offers 5 bidirectional inputs and outputs for connecting different network access points. Each of the 5 ports can be fed separately with a composite RF signal. A freely programmable mixture of the other 4 signals can then be set individually for each port. The levels can be varied in a wide dynamic range by means of internal precision attenuators. The AIE-W5LR enables a realistic air interface to be simulated in which connected access points simultaneously receive field signals of different strengths from other access points in the network.

 

*Key Features

matrix function

The AIE-W5LR can also be used as a non-blocking matrix switcher. Each input and output can be connected to the other ports in any way. Attenuators between the signal paths also allow the emulation of fading effects. Due to the fast response time of the attenuators, the device is ideally suited for efficient and quick solutions in automatic test systems.

bandwidth

The operating bandwidth is 500MHz to 9000MHz. Therefore, the AIE-W5LR is usable for all Wi-Fi standards including 802.11p for V2X and V2V communication.

High dynamics

The setting range of the digitally controlled attenuator is 127.0 dB and can be freely adjusted in 0.25 dB increments. This enables use in test applications with the highest demands on dynamics and accuracy. The high attenuation range reduces RF signal levels below the sensitivity limit of connected devices. All of the device’s RF connections allow power levels of up to 2 watts.

synchronous operation

The AIE-W5LR can be conveniently and efficiently remotely controlled via LAN and USB interfaces and an additional TRIGGER-IO port. With each execution of switching commands, the trigger interface supplies a precise voltage pulse that can be used for the synchronous execution of switching commands from other devices in the compound. In addition, external pulses can be applied to this port in order to synchronously trigger the execution of pending switching commands. The emulator’s attenuator configuration can be preloaded with SCPI-oriented ASCII strings in a queue over the LAN interface. After a positive TTL pulse edge at the trigger input, the preloaded damper configuration is then executed by the hardware without delay.
