This product has been discontinued
Overview
  • Supports LTE-Advanced FDD/TDD Carrier Aggregation (CA) 2CCs and 3CCs
  • Supports LTE-Advanced FDD/TDD Release 12
  • One MD8430A supports CA handover, 4×4 MIMO and 8×2 MIMO
  • Supports full-digital fading test
  • Supports DL 450 Mbps (3CCs), UL 100 Mbps throughput test
  • Inter-RAT tests making effective use of previous MD8480C (UTRAN/GERAN), and MD8475A (CDMA2000) hardware investments
  • Optimized investment from first R&D to protocol conformance testing
  • Full development and analysis toolset cuts L1, L2 and L3 scenario development time and costs

Wireless devices are evolving quickly into multimedia smartphones with fast data connections due to widespread deployment of high-speed standards, such as LTE/LTE-Advanced. The Signalling Tester MD8430A is a key LTE-Advanced base station simulator for developing LTE-Advanced-compliant chipsets and wireless devices. In addition to verifying normal communications procedures, it supports fault operation tests, which are difficult to perform at connection with live base stations. It also supports LTE/LTE-Advanced terminal R&D and verification tests under various conditions. Based on extensive experience in 3G markets, Anritsu has developed the MD8430A as a powerful LTE-Advanced protocol/R&D test solution to help developers bring LTE-Advanced wireless devices to market as fast as possible.

A choice of MD8430A models designed for early chipset and UE development, function tests, and performance tests ranging from carrier acceptance to protocol conformance tests, plus retrofit upgrades between models, allows developers to customize their hardware investment to current needs while assuring flexible future upgrade options.
