MIMO Measurements made simple

 

The EMITE-patented testing technology originated in the cuttlefish eye, a technology from nature, which instead of observing the amount of light, it observes the changes in the polarization of light. With an extension to the UE, the USA, Japan and South Korea, the EMITE patents have been granted the highest qualification rank. The W-shaped cuttlefish eye, when moved to a multiple-cavity reverberation chamber by EMITE, separates transmit from receive antennas and enhances the repeatability of results by including multiple sources at the lower cavity for each transmit signal into the upper cavity. The multiple-cavity design is enhanced by an additional cavity for equipment, cables and electronics. With the lower measuring cavity free of electronics, system accuracy also improves over conventional single-cavity designs. Multiple antenna sourcing, also known as source-stirring, is also patent-protected by EMITE. Multiple antennas act as transmit antennas in the upper cavities. Stirring is further enhanced with polarization stirring by using different polarization schemes in the transmit antennas, with platform stirring by a rotating platform where both the reference antenna and the antennas or devices under test are placed, and with frequency-stirring in passive mode by adding to the sample set for a specific frequency value those samples in neighborhood values in a manner which is user-specified. The result is the most-advanced most-accurate and fastest multiple-cavity mode-stirred source-stirred reverberation chamber in the market. A nice outfit design presents it to the customer. Finally, as in any other test equipment, the unit interacts with the user with a Front Panel, a Back Panel and a very intuitive and easy-to-use Graphic User Interface (GUI) software. An engineer can be trained within 1 day to fully use the EMITE Test Systems in their entire capabilities. Any auxiliary equipment needed for the test, including Vector Network Analyzers (VNAs), base station emulators (BSE or eNodeBs, gNB), channel emulators (CEs), Access Points (APs) or wireless STAtions (STAs) are fully-controlled by EMITE GUI Software, really making MIMO measurements simple for the end-user.

EMITE test systems can accommodate small devices (up to 8 smartphones) in the PT-Series, medium devices (smartphones, tablets, access points and notebooks) in the E-Series and large devices and front-ends (smartphones, tablets, access points, notebooks, monitors, trash compactors, frontal car parts, fridges, serving machines, etc.) in the F-Series.

 

 

H-Series - Small-size Compact Antenna Test Range (CATR)
mm-Wave 5G OTA testing
3 to 30/40/110 GHz

The H-Series CATR chamber provide complete 3D performance assessment for 5G OTA devices and antennas including gain, efficiency, directivity, polarization and beam characteristics for frequencies from 3 up to 110 GHz, capable of supporting forthcoming 5G Sub-6 GHz (from 3 to 6 GHz) and mmWave (24 to 110 GHz) standardized testing including TRP/TIS, EIRP, EIS, IBB and emissions in accordance to 3GPP TR38.810 and TR37.842. The nature of 5G Sub-6 GHz and mmWave frequencies makes OTA testing extremely sensitive to physical positioning and to phase and gain measurement accuracy, and for this reason aerospace-used technology has been incorporated into our H-Series chambers. With serrated reflectors providing unique 15µm peak-to-peak roughness in 30/60 cm quiet zone. High accuracy 0.03° positioners are included, with both roll over azimuth and roll over elevation. Undoubtedly, the H-Series is a best-in-its-type chamber, and the only one in the market capable of testing FR1 Sub-6 GHz and FR2 mmWave frequencies in a simultaneous manner.

I-Series - Small-size Reverberation Chamber
Internet of Things (IoT), Machine-Type-Communications (MTC), short-range communications and WLAN testing
690MHz to 6GHz

The I small-size Reverberation Chamber Series is an amber gem set of OTA test chambers. With smart-stirring, the I-Series chambers have the smallest footprint in the market and are intended for IoT (LTE-M, NB-IoT and EC-GSM-IoT), MTC (LoRa, Sigfox), short-range radio technologies (BT 1.0/2.0, BLE, ZigBee, Z-Wave) and WLAN 802.11abgnac (2.4 and 5 GHz bands) for small devices up to 15cm and 5kg. The I-Series chambers provide for fast and accurate TRP, TIS, downlink and uplink Maximum Coupling Loss (MCL) and Downlink and Uplink TCP/UDP MIMO TPUT tests for UEs, IoT modules, wearable devices, wireless stations (STAs) and Access Points (APs), also with user-selectable technology, band, channel (including DFS ones), bandwidth, antennas, rates (MCS) and other parameters in an individual manner for each test on a batch, which can then be run overnight in an unsupervised manner, something that only the Test Systems from EMITE can do.
