The MT8821C operates as a 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 simplifies configuration by using preset measurement parameters for test items specified by the 3GPP RF test standards. Additionally, parameters for all tests can be set and changed using the touchscreen GUI. 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 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 offers improved functionality, greater platform integration and an updated user interface, and is backwards compatible with its predecessor, the MT8820C.
