SY-16M has been repeatedly ordered by Spreadtrum Communications, and been delivered to several research centers around the world for its reliable and proven performance.
SY-16M System Features:
Portable and Moveable: The system comes with an anechoic chamber, with volume much smaller than traditional anechoic chamber. Itprovides a permanent solution to overcome defects of traditional anechoic chamber: occupies too much space; requires for installation; and inconvenient to move.The system can move in any direction without affecting its performance, and it is very convenient to carry out movement of spatial orientation, relocation and system sharing among divisions.
Cost effective: No shielding anechoic chamber required, and relocation cost saved due to its movable feature;
Faster Measurement: With multi probes in cyclic symmetric distribution, 3D measurement can be performed on DUT with a 180-degree rotation in horizontal direction under normal circumstances, and the measurement speed is much faster than measurement system with other probe distribution style.
Real-time display: The supporting analysis software provides real-time computing and display functions, which allow real-time viewing of active and passive directivity diagram as well as active power and sensitivity.
Powerful Function: It supports active measurement in most standards, such as 2G, 3G, 4G, WIFI, GPS, BT etc. With frequency range between 650MHz and 6GHz, it also supports passive measurement with the same frequency range. Through upgrade, it can support passive test for high frequency version between 6GHz and 18GHz.
Strong Compatibility: It is compatible with common network analyzers and comprehensive measuring and test instruments by Keysight, Rohde & Schwarz and Anritsu etc.
Smooth Upgrade: The system can conduct LTE-CA measurement after software and hardware upgrade and it can also be upgraded to support passive test for high frequency version between 6GHz and 18GHz.
