W9073A W-CDMA/HSPA+ Measurement Application for CXA

The W9073A is discontinued after June 1, 2019. The replacement model is the N9073EM0D X-Series Measurement Application with KeysightCare.

Signal analysis

• W-CDMA, HSPA, HSPA+ per 3GPP TS 25 standard
• Uplink and downlink RF transmitter measurements
• One-button measurements with pass/fail per the standard
• Runs inside CXA signal analyzer

Measurements

• Downlink: EVM, frequency error, CPICH power accuracy, 64QAM RCDE, SEM, ACLR and more
• Uplink: EVM, frequency error, PkCDE, RCDE, PRACH power, slot power, SEM, ACLR and more
• Automatic detection of scrambling code, all active channels and signals plus predefined test models (TM1 to TM6)
• Multiple result views: constellation diagram, code domain, numeric display, spectrum, time domain

Performance

• Composite EVM floor: 1.6 %
• ACLR: −73 dBc (typical) with noise correction
• Absolute power accuracy: ±0.61 dB
• Analysis bandwidth: up to 25 MHz

Other features

• License key upgradable
• Fixed and transportable license available
• SCPI remote user interface

The W9073A W-CDMA/HSPA+ measurement application for the CXA is one in a common library of more than 25 measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. Transforming the X-Series signal analyzer into a standard-based transmitter tester, the application provides fast one-button RF conformance measurements to help you design, evaluate, and manufacture your W-CDMA/HSPA/HSPA+ 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

• Low-cost tool especially in user equipment (UE) device development and low-volume manufacturing.
• 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.
• 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.
