ETS-Lindgrens AMS-7000 Wireless OTA Reverb Test System is designed to perform accurate and repeatable SISO TRP, TIS and Throughput measurements. The system is based on ETS-Lindgrens longstanding line of SMART™ reverberation chambers, and proven EMQuest antenna measurement automation software.SISO TRP, TIS and ThroughputTRP measurements made in a reverb chamber rely on a continuous sampling of the average power density in an over-moded environment while the DUT is transmitting at its full power. The accuracy with which the average power can be measured directly correlates with the number of independent samples that are taken.The TIS measurement is the converse of TRP. The power density in the chamber is controlled for the downlink path by the communication tester. The DUT responds to samples of this environment as it is moved to a series of different locations in the varying modal environment. The TIS value is then derived from the reported data validity threshold after chamber corrections are applied.The reverb chambers over-moded environment also means that the precise location of the DUT is not critical to achieve good measurement repeatability or accuracy, resulting in reduced setup time.MIMO Throughput MeasurementsMIMO throughput is ultimately a measure of the ability of the DUT to maximize its data throughput under different controlled environmental multi-path conditions. The reverb chamber is already a multi-path environment with path lengths limited by the chamber dimensions, exhibiting a signal decay profile dependent on the loss in the chamber.For MIMO throughput measurements, a simplified representation of the real world environment can be created by duplicating how the averaging effect of the chamber would be seen by a MIMO device. Different delay profiles can be realized by changing the selection of small RF Absorber loading elements fitted to the chamber. Additional delays and more complex propagation models can be introduced with an optional channel emulator.Operates with EMQuest SoftwareThe AMS-7000 system utilizes EMQuest Antenna Measurement Software, a software suite used by antenna measurement labs worldwide. Most popular brands of instrumentation, communication testers, protocols etc. are supported by EMQuest, providing greater flexibility in configuring equipment. EMQuest also works equally well for reverb or RF anechoic-based systems. This eliminates a steep learning curve for operators and technicians working between systems, and assures consistency of processes.Supported MeasurementsTotal Radiated Power (TRP)Total Isotropic Sensitivity (TIS)MIMO Data ThroughputAntenna Efficiency
