Signalling Tester (Base Station Simulator) MD8475B

The MD8475B Signalling Tester by Anritsu is an all-in-one base station simulator ideal for performance, functional, and IMS service testing of multimode mobile terminals. It supports LTE-Advanced up to 5CA, 2 Gbps downlink IP throughput, and multimode technologies including W-CDMA, GSM, and TD-SCDMA. Equipped with a built-in traffic generator, CSCF server, and SmartStudio GUI, the MD8475B enables easy setup of VoLTE, data throughput, handover, and inter-RAT tests—perfect for advanced mobile device testing in both lab and automated environments..

  • Special Features
  • Specification

The MD8475B is a highly integrated signalling test platform that simulates 2G, 3G, and 4G radio access networks to validate and verify user equipment (UE) behavior under real-world conditions. With support for up to 5 Carrier Aggregation (CA) scenarios and 2x2 or 4x4 MIMO, it enables efficient LTE-A performance testing, throughput validation, and mobility scenarios such as cell reselection, redirection, fallback, and inter-RAT transitions.

SmartStudio, the included GUI environment, allows users to run functional tests without writing test scripts, making it ideal for both engineers and QA teams. Meanwhile, developers can switch to Script Mode to create custom SIP-based IMS testing or simulate abnormal call conditions.

The tester includes VoLTE, eCall (ETSI, CEN), NG-eCall, and ERA-GLONASS services, fulfilling regional compliance needs for emergency communication. Additional capabilities include WLAN offload testing, multi-cell simulation, and continuous automated testing using SmartStudio Manager, which also controls connected Android devices for synchronized scenarios.

  • All-in-One 3G/4G Simulator: Supports LTE/LTE-A (up to 5CA), W-CDMA, GSM, and TD-SCDMA in one platform.

  • 8TX / 4RX Port Design: Enables complex multi-carrier and multi-antenna setups (up to 6 GHz).

  • Built-in Traffic Generator: Provides up to 2 Gbps DL and 150 Mbps UL IP throughput testing.

  • SmartStudio GUI: Enables easy test setup for VoLTE, call processing, and IMS-based testing without scripting.

  • Integrated CSCF Server: GUI-based IMS/VoLTE test environment including eCall and NG-eCall.

  • Automated 24/7 Testing: Compatible with SmartStudio Manager for continuous and unmanned device evaluation.
