- W-CDMA/HSPA/HSPA Evolution

The MD8475A Signaling 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 2x2 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.
