Tektronix adds HSDPA to wireless analyzers

Tektronix now has High Speed Downlink Packet Access test capability in its WCA200A series of Wireless Communications Analyzers used for the development of next-generation mobile users and network equipment. The addition will enable designers and manufacturers to test their latest wireless device designs that incorporate HSDPA technology. As one of the latest next-generation technologies, HSDPA has the potential to extend 3G capabilities to enable an all-IP network that merges wireless and wireline infrastructure by significantly enhancing peak data rates, quality of service and spectrum efficiency.

HSDPA uses adaptive modulation and coding to increase user data rates in the downlink direction (transmission from the radio access network to the mobile terminal). Adaptive modulation allows the network operator to change modulation formats, in real-time, providing faster data rates and improved spectrum efficiency. Tektronix' Wireless Communication Analyzers incorporate real-time spectrum analysis that addresses adaptive modulation. Real-time spectrum analysis allows the user to trigger, capture and analyze transient anomalies that can occur during the dynamic changes in modulation. Seamless capture of the RF signal enables the designer to analyze the signal before, after and during the transient event. The WCA200A Series includes the WCA230A (3GHz) and the WCA280A (8GHz) analyzers.
