Function & Features
Test the specific functional characteristics of the system
✔ IoT Communication Modes：LTE Cat NB1 (NB-IoT)/Cat-M1 (e-MTC)/Lora/Zigbee/UWB
✔ Test Frequency：400MHz-7.5/11GHz
✔ SISO：TRP/TIS/EIRP/EIS
✔ MIMO 2×2/4×4 throughput test; the test system used to passed CTIA MIMO multi-probe certification; 2D/3D channel model is supported.
✔ Passive Antenna Test, Desense Test, ICS, CA (2CC/3CC/4CC), and communication coexistence test are supported.
✔ The original IoT terminal performance grading software helps users make good use of test results.
✔ The antenna ring use EPP hard material which is hard to deform, that ensures a long-term stable performance of antennas. The test system uses low insertion loss RF components, such as power amplifier and RF switch. Even in high temperature environment for 24 hours, the data variation of components could be lower than 0.1dB. The regular normalization test also makes sure the insertion loss variation of all 46 test paths in control.
✔ The same size anechoic chamber has a larger test distance. With Hwa-Tech antennas which have better bandwidth, the system could have a test area that 30% larger than the general system.
