M9073A W-CDMA/HSPA+ Measurement Application

The W-CDMA/HSPA+ measurement application is one in a common library measurement applications for the Keysight modular PXI VSAs, providing standard-based transmitter tests by adding fast one-button RF conformance measurements to help you design, evaluate, and manufacture your W-CDMA/HSPA+ base station and user equipment devices. The measurement application closely follows the 3GPP standard allowing you to stay on the leading edge of your design and manufacturing challenges.

RF transmitter testing

• Simplify measurement setup with one-button measurements for both downlink and uplink in a single option with pass/fail limits in accordance with 3GPP TS25.141 and TS34.121 specifications.
• Expedite troubleshooting and design verification using a rich selection of traces: I/Q measured polar graph; code domain power; peak/avg metrics showing numeric result table with average and peak hold statistic results; capture time summary showing a summary table with measurement results of multiple slots; slot CDE/EVM showing EVM, peak CDE, and frequency error in three windows.
• Perform adjacent channel power measurement over wide dynamic range. Perform single-carrier and multi-carrier ACLR measurements on base station systems, as well as components such as amplifiers that have to meet more stringent requirements.
• Characterize your UE device using the uplink power control measurement. The power control measurement includes: slot power, PRACH power and slot phase. In addition to slot power, slot phase measures phase error, frequency error and EVM of uplink slots plus it is used for 3GPP UE phase discontinuity.
