W-CDMA/HSPA+

X-Series Measurement App, Multi-Touch

N9073C

Technical Overview

• Perform W-CDMA, HSPA, and HSPA+ downlink and uplink transmitter test per 3GPP standard
• Perform one-touch tests with pass/fail limit per 3GPP standard
• Use multi-touch user interface or SCPI remote interface
• Leverage built-in, context-sensitive help
• Extend test assets with transportable licenses between X-Series signal analyzers with multi-touch UI

W-CDMA/HSPA+ Measurement Application

The W-CDMA/HSPA+ measurement application transforms the X-Series signal analyzers into 3GPP standard-based transmitter testers. The application provides fast, one-touch RF conformance measurements to help you design, evaluate, and manufacture your W-CDMA/HSPA/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.

X-Series measurement applications

X-Series measurement applications increase the capability and functionality of Keysight Technologies, Inc. signal analyzers to speed time to insight. They provide essential measurements for specific tasks in general-purpose, cellular communications, wireless connectivity and digital video applications, covering established standards and modulation types. Applications are supported across X-Series analyzers, with the only difference being the level of performance achieved by the hardware you select.

Top Features

With the W-CDMA measurement application, you can perform RF transmitter measurements on eNB and UE devices in time, frequency, and modulation domains. Measurement setups are simplified with automatic detection of downlink channels and signals. For eNB conformance testing, measurement is simplified by recalling E-TM presets according to 3GPP TS 25 standard.

• 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
• Add real-time spectrum analyzer (RTSA) capability to the PXA or MXA signal analyzers to pinpoint interference caused by multi-carrier W-CDMA signals or other events in the transmitter

Downlink eNB measurements

• EVM, frequency error, CPICH power accuracy, 64QAM RCDE, SEM, ACLR and more
• Perform adjacent channel power measurement over wide dynamic range (up to –88 dBc) on 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

Uplink UE measurements

• EVM, frequency error, PkCDE, RCDE, PRACH power, slot power, SEM, ACLR and more
• Characterize your UE device using the uplink power control measurement. The power control measurement includes: slot power, PRACH power and slot phase
• Evaluate 3GPP UE phase discontinuity EVM of uplink slots with slot power and phase measurements

Measurement details

All of the RF transmitter measurements as defined by the 3GPP standard, as well as a wide range of additional measurements and analysis tools, are accessible directly on the instrument's touch screen (Tables 3 and 5). These measurements are fully remote controllable via the IEC/IEEE bus or LAN, using SCPI commands. Analog baseband measurements are available on the PXA or MXA signal analyzer equipped with BBIQ hardware. Supported baseband measurements include all of the modulation quality plus I/Q waveform measurements.

Key Specifications

Definitions

• 95th percentile values indicate the breadth of the population (≈2σ) of performance tolerances expected to be met in 95% of cases with a 95% confidence. Typical values are designated with the abbreviation "typ." These are performance beyond specification that 80% of the units exhibit with a 95% confidence. Nominal values are designated with the abbreviation "nom." These values indicate expected performance, or describe product performance that is useful in the application of the product.

Ordering Information

Software licensing and configuration

Choose from two license types

• Fixed, perpetual license:

This allows you to run the application in the X-Series analyzer in which it is initially installed.

• Transportable, perpetual license:

This allows you to run the application in the X-Series analyzer in which it is initially installed, plus it may be transferred from one X-Series analyzer with multi-touch UI to another.

Hardware Configuration

For optimizing measurements on W-CDMA signals with W-CDMA measurement application, Keysight recommends a minimum level of X-Series multi-touch instrument hardware functionality at each instrument performance point.

Supported instruments include:

• UXA N9040B
• PXA N9030B
• MXA N9020B
• EXA N9010B
• CXA N9000B
