M9073A W-CDMA/HSPA+

W-CDMA/HSPA+ X-Series Measurement Application for Modular Instruments 

Expand the capabilities of your M9391A and M9393A PXIe vector signal analyzers (PXI VSAs) with the Keysight Technologies, Inc. library of measurement applications – the same applications used to increase the capability and func­tionality of its X-Series signal analyzers. Eleven of the most popular applications are now available for use with Keysight’s new M9393A PXI Performance VSA and the M9391A PXI VSA. When you combine the raw hardware speeds of the PXI VSAs and the X-Series measurement applications for modular instruments, you can test more products in less time while ensuring measurement continuity from design to manufacturing.  The M9073A W-CDMA/HSPA+ X-Series measurement application for modular instruments transforms the PXI VSAs into 3GPP standard-based transmitter testers. The application provides fast, RF conformance measurements to help you speed up manufacturing of 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 several measurement applications in the Keysight X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements, and software. Proven algorithms, and a common user interface across the X-Series analyzers and modular PXI VSAs 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. You can further extend your test assets by utilizing up to four PXI VSAs with one software license. Keysight’s X-Series applications for modular instruments include a unique “Resource Manager” that provides direct access to PXI VSA hardware drivers for the fastest power and spectrum-based measurements, while simultaneously using the X-Series applications for fast modulation quality measurements and 89600 VSA for fast spectrum measurements. 

W-CDMA/HSPA+ 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).
