The WCA200A Series enables in-depth characterization, troubleshooting, and verification in 2.5G and 3G designs. The analyzers unite vector signal analysis and spectrum analysis capabilities into one instrument. The Frequency Mask Trigger feature has both frequency and amplitude parameters that can be set independently of one another. The Codogram Display is useful for analysis of WCDMA Compressed Mode behavior. The codogram can be coupled with simultaneous correlated views of time vs. power and the code domain to assess performance in handover situations. The instruments can be equipped with deep acquisition memory (up to 256 Mbytes).
