Product Brochure Radio Communication Analyzer MT8821C

Tomorrow's Wireless Test Capability Today The Radio Communication Analyzer MT8821C is designed for R&D into mobile devices (User Equipment: UE), such as smartphones, tablets and M2M/IoT modules. It builds on the technologies of its popular predecessor, the MT8820C used worldwide by UE and chipset vendors. It operates as a base station simulator using standard call processing sequences compliant with test standards to support a versatile test lineup, starting with RF tests. More Efficient RF Testing Supporting LTE-Advanced UE Measurement With the introduction of LTE-Advanced, wireless...

Wireless Communication Tester for LTE-Advanced UE Development LTE/LTE-Advanced W-CDMA/HSPA Cat-M/NB-IoT (Cat-NB1, 2) GSM/EGPRS TD-SCDMA/HSPA

Nex t- generation GUI with L arge Touch Panel Enhanced GUI for Efficient Operability Better operability and visibility have been achieved using an enhanced next-generation GUI and easy-to-use large touch panel. As well as operating screens by touching and swiping, easy operation is supported by one-touch switching between grouped/individual graph lists and results outline/detail displays. Further, the efficiency of complex setting work is improved by a parameter search function, bookmarking function for commonly used parameters, and a function for setting test parameters using one-touch button...

Radio Communication Analyzer MT8821C Features RF TRX Measurement 3GPP UE RF Measurement One-touch Settings and PASS/FAIL Judgment Until now, LTE CA measurements have required complex Component Carrier (CC) settings, making operation difficult, but the MT8821C integrates multiple related parameters settings into one operation, greatly simplifying each operation stage to reduce setting operations and time. The UE TRX characteristics must be evaluated for compliance with 3GPP/3GPP2 standards at chipset and UE development, evaluation, and acceptance testing by network operators, etc. UE...

Radio Communication Analyzer MT8821C Features RF TRX Measurement (continued) Flexible Parameter Setting The MT8821C runs TRX measurements using parameters specified by the 3GPP/3GPP2 RF test standards. In addition, flexible parameter settings support both RF parametric and a range of protocol testing. Recent UE designs support multiple frequency bands, requiring a lot of time for RF calibration. With high-speed measurement supported by chipsets vendors, the MT8821C increases measurement efficiency by reducing time required for RF calibration. Segment Trigger Frequency change step High...

Radio Communication Analyzer MT8821C Features Functional Testing Over The Air (OTA) Testing The UE TRX performance is affected by factors such as the antenna form and characteristics. The OTA test measures the total UE TRX performance using actual radio waves reaching the antennas. The MT8821C supports the various OTA vendor test system configurations in compliance with the 3GPP TS 34.114 and CTIA Total Radiated Power (TRP), and Total Radiated Sensitivity (TRS) test standards. Although one MT8821C unit can output up to 8 independent signals, DL 4CA 4×4 MIMO measurements require output of 16...

Radio Communication Analyzer MT8821C Features Functional Testing (continued) Power Consumption Testing Battery power consumption is a key point in differentiating chipsets and smartphones. As well as supporting the GSMA-defined power consumption tests, the MT8821C also supports power consumption tests at the maximum IP data throughput. VoLTE Voice/Video Echoback Testing As VoLTE offering high-quality and low-latency voice calls becomes the de facto communications technology for recent UE, there is increasing demand for power consumption measurements during VoLTE calls as well as for...
