AIE-4X4LR
The AIE-4X4LR radio field emulator enables the realistic simulation of RF levels for wireless communication between mobile devices and wireless networks such as Wi-Fi or LTE. The device features 4 RF ports for base stations and 4 ports for DUTs (Devices Under Test), such as mobile phones. All signal paths are bidirectional. Each of the 4 DUT ports can be fed with an individually composed RF signal from the 4 base station ports. Likewise, the base stations can receive individually composed signals from the 4 DUT ports. The signal levels can be adjusted for each signal path using internal attenuators over an extended dynamic range.
Due to the device’s wide frequency bandwidth, it can be used flexibly for almost all common wireless transmission standards, including GSM900, GSM1800, UMTS, LTE 4G, LTE 5G FR1, LTE6G, IEEE 802.11a/b/g/n/ac/ax (Wi-Fi 6E), and 802.11be (Wi-Fi 7). The reproducible emulation of air interface scenarios in a laboratory environment saves time and costs in product development and verification.

Matrix Function
The AIE-4X4LR can also be used as non-blocking matrix. Every output has free access to each input. Attenuators between the signal paths allow also the emulation of fading effects. With a fast attenuator response time, the device is an efficient and fast solution for automatic testing systems.
Wideband
The operating frequency range covers more than 500 MHz to 9000 MHz. Therefore, the AIE-4X4LR is useable for all cellular standards and Wi-Fi standards including 5G (FR1).
High Dynamic
The setting range of the digitally controlled attenuators covers 63.5 dB and is adjustable in 0.25 dB steps. This allows test scenarios with highest requirements for dynamics and accuracy. All RF ports of the air emulation system allow signals levels of up to 2 Watts.
Synchronous Operation
For remote control the AIE-4X4LR offers LAN and USB interfaces. AIE-4X4LR offers additional a TRIGGER IO port. This Interface provides a precise trigger pulse which complies with the physical execution of the applied switching command. On the other hand, external pulses can be applied to this port in order to trigger the execution of queued switching commands synchronously. The attenuator configuration of the emulator can be preloaded with SCPI oriented ASCII strings via LAN interface without execution. After a positive TTL pulse slope at the trigger input, the preloaded attenuator configuration will be executed only by hardware in micro seconds.
