Description
The MD8475A Signalling Tester is an all-in-one base station simulator supporting LTE FDD, W-CDMA/HSPA/HSPA Evolution/DC-HSDPA, GSM/(E)GPRS, and CDMA2000® 1X/1xEV-DO Rev. A. It supports service and call-processing tests for multimode LTE smartphones and mobiles with excellent cost-performance.
A full line of test environments are supported for the general mobile verification phase, such as max. throughput performance tests, stress tests, and battery consumption tests of multisystem LTE mobiles using 2×2 MIMO, as well as CS-Fallback, call connection reliability and stability tests at handover, communication tests at low RF power, and service verification using LTE Multiple PDN and SMS in a 2-cell environment*.
In addition, test conditions are easily set using the SmartStudio GUI, helping cut test environment configuration time.
*: Supports combination of LTE/LTE, LTE/W-CDMA, LTE/GSM and LTE/CDMA2000; requires two MD8475A units for testing LTE/CDMA2000.
