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-button 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.

The W-CDMA/HSPA+ measure­ment application 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. The X-Series analyzers, with upgradeable CPU, memory, disk drives, and I/O ports, enable you to keep your test assets current and extend instrument longevity. Proven algorithms, 100% code-compatibility, and a common UI across the X-Series create a consis­tent measurement framework for sig­nal analysis that ensures repeatable results and measurement integrity so you can leverage your test system software through all phases of prod­uct development. In addition to fixed, perpetual licenses for our X-Series measurement applications, we also offer transportable licenses which can increase the value of your invest­ment by allowing you to transport the application to multiple X-Series analyzers.

Choosing Between X-Series Applications and 89600 VSA Software

X-Series measurement applications provide embedded format-specific, one-button measurements for X-Series analyzers. With fast measurement speed, SCPI programmability, pass/fail testing and simplicity of operation, these applications are ideally suited for design verification and manufacturing. 89600 VSA software is a comprehensive set of tools for demodulation and vector signal analysis. These tools enable you to explore virtually every facet of a signal and optimize your most advanced designs. Use the 89600 VSA software with a variety of Keysight hardware platforms to pinpoint the answers to signal problems in R&D.

Technology Overview

Wideband code-division multiple-access (W-CDMA) is one of the main technologies for the implementation of third-generation (3G) cellular systems. Release 99 of the 3GPP specifications provided the evolutionary path for GSM, GPRS, and EDGE technologies, enabling more spectrally efficient and better performing voice and data services through the introduction of a 5 MHz W-CDMA carrier.

High speed downlink packet access (HSDPA), the first step in the evolution of WCDMA was introduced in Release 5 of the 3GPP standard. HSDPA enhances the WCDMA downlink packet-data performance and capabilities in terms of higher peak data rate, reduced latency, and increased capacity.

High-speed uplink packet access (HSUPA) also known as “enhanced uplink” was introduced in W-CDMA Release 6. It provides improvements in W-CDMA uplink capabilities and performance in terms of much higher data rates in the uplink, reduced latency, and improved system capacity and is therefore a companion technology to HSDPA. Together, HSDPA and HSUPA are commonly referred to as high-speed packet access (HSPA).

HSPA+, also known as “HSPA evolution,” was introduced to W-CDMA in Release 7 with significant enhancements in Releases 8, 9 and 10 of the 3GPP standard. 3GPP Release 7 of the standard introduced new major HSPA+ features such as multiple input multiple output (MIMO) for downlink as well as higher order modulation; 64QAM in the downlink and 4PAM (16QAM) in the uplink. However, for downlink, it only allowed operation for either MIMO or the 64QAM. Release 8 of the standard allowed simultaneous operation of 64QAM and MIMO as well as defined dual carrier operation in the downlink (dual cell HSDPA). Release 9 of the standard defined dual carrier operation in the uplink (dual cell HSUPA), dual band HSDPA as well as combination of dual cell HSDPA and MIMO. Release 10 of the standard introduced four carrier HSDPA (quad-cell HSDPA).

RF Transmitter Tests

With the X-Series signal analyzers and the W-CDMA/HSPA+ measure­ment application you can perform RF transmitter measurements on base station and user equipment devices in time, frequency, and modulation domains. Measure basic W-CDMA signals as well as HSPA (HSDPA/HSUPA) and HSPA+ signals with all channel configurations.

For high-speed manufacturing, a single acquisition combined W-CDMA measurement is available where the speed is up to 20 times faster than traditional one-button measurements (for details refer to Ordering Informa­tion).

Standard-based RF transmitter tests

The RF transmitter test require­ments for W-CDMA/HSPA/HSPA+ are defined in 3GPP TS 25.141 (BTS) and 3GPP TS34.121 (UE) of the 3GPP standard. Table 2 shows the 3GPP re­quired BTS RF transmitter tests along with the corresponding measure­ments available in the X-Series and 89600 VSA W-CDMA applications. Table 4 shows similar information for UE transmitter tests.

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 available with a press of a button (Table 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.

Single acquisition combined measurements

The N9073A-XFP single acquisition combined W-CDMA measurement application is for high-speed manu­facturing of W-CDMA mobile phone transmitters, wireless components, such as power amplifiers, and low-cost pico/femtocell base stations. Used with the MXA and EXA signal analyzers, it provides up to 20 times speed improvement compared to traditional one-button measurements for a combined W-CDMA ACP, modulation quality (Rho) and QPSK EVM.
