With the new options, the MT8222A and MS272xB can support HSPA+ 64 QAM modulation, and a 64 QAM constellation diagram can be displayed on the respective analyzer’s measurement screen. The new software also adds support for discontinuous transmission (DTX) and Adaptive Multi-Rate (AMR).
Over-the-Air (OTA) measurement capability has been enhanced with the new options, as well. OTA scanner measurements can be made twice as fast, and users experience improved Code Domain Power (CDP) measurement performance, due to lower EVM. Additionally, more active channels can be displayed.
The new options complement the existing W-CDMA and HSDPA measurement capabilities of the MS272xB handheld spectrum analyzers and MT8222A base station analyzer. Both instruments can conduct all the major RF and demodulation measurements on W-CDMA and HSDPA OTA signals.
