Communications analyser for next-generation networks said to be highly versatile
2 July 2003
Test & Measurement
Tektronix has unveiled a new wireless communications analyser that combines vector signal analysis and spectrum analysis in one instrument to improve engineers' view and enable next-generation wireless design and manufacturing.
As next-generation (2,5 and 3 G) networks begin to roll out, mobile devices must be available to ensure end-user adoption and revenue realisation. As a result, RF engineers working on 2,5 and 3 G designs are pressured more than ever to get devices to market in order to meet financial and subscriber expectations. The design challenge of integrating more complex 2,5 and 3 G components into small mobile devices presents a demand for flexible, affordable test tools that provide fast, accurate measurements. To answer this need, Tektronix designed the wireless communications analyser 200 A series (WCA200A series), which combines one-button measurements, versatile troubleshooting capabilities and spectrum analysis in one instrument.
With measurement capabilities not typically found in this class of analyser, features include simultaneous multidomain analysis, frequency mask trigger, unmatched memory capture (up to 10 seconds of WCDMA signals), and superior adjacent channel leakage ratio (ACLR) measurement speeds. These versatile features are in addition to the standard one-button measurements found in existing vector signal analysers. Also, the instrument has advanced analysis and triggering capabilities that allow developers to improve their view by capturing random spurious signals and analysing them in frequency, time and modulation domains without having to take multiple measurements.
Previously, according to Tektronix, design engineers have been required to choose either a standards-oriented vector signal analyser with limited spectrum analysis capability or a spectrum analyser with limited demodulation capabilities, requiring a great deal of set up time and operator knowledge. The WCA200A Series debuts superior versatility, providing spectrum analysis, flexible demodulation and in-depth troubleshooting. The WCA200A Series includes the WCA230A (3 GHz) and the WCA280A (8 GHz) analysers.
