Radio communication analyser supports LTE-Advanced

June 01, 2015 // By Graham Prophet
Anritsu’s MT8821C addresses the need for measurement tools that support wider bandwidths using LTE-Advanced CA and higher-order MIMO technologies.

MT8821C is a Radio Communication Analyser for research and development testing of mobile devices (User Equipment, UE) with the widest capability for supporting LTE-Advanced. As well as supporting LTE-Advanced, the all-in-one MT8821C operates as network simulator supporting LTE, W-CDMA/HSPA, GSM/GPRS/EGPRS, TD-SCDMA/HSPA, and CDMA2000 1X/1x EVDO technologies to run RF TRX tests in compliance with the 3GPP and 3GPP2 standards, as well as parametric tests.

The MT8821C eliminates setting and operation errors, simplifying configuration by using preset measurement parameters for test items specified by the 3GPP RF test standards. Parameters for all tests can be set and changed using the advanced Graphical User Interface, which includes touch screen operation. An advanced parameter search function enables complex user test settings to be configured, and automatic PASS/FAIL judgment of measured results according to test specification speeds up testing.

The MT8821C supports additional functional tests, such as maximum throughput tests. With eight transmitter ports and two receiver ports, a single system will perform LTE-Advanced Carrier Aggregation (CA) with up to four Component Carriers (CCs) using 2 x 2 MIMO. A built-in RF combiner simplifies configuration of complex test environments for LTE-Advanced CA, while reducing calibration procedures of test environments.

The MT8821C is successor to the MT8820C, used worldwide by developers of 2G/3G and LTE UE and chipset. It offers improved functionality, greater platform integration and an updated user interface, and as it is backwards compatible with the MT8820C, it maximises the value of previous investments and reduces the cost of configuring automatic test environments when moving to MT8821C.
