M(072A cdma2000/cdmaOne, X-Series Measurement Application for PXI Vector Signal Analyzers - Technica

cdma2000/cdmaOne 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 cdma2000/cdmaOne X-Series measurement application for modular instruments transforms the PXI VSAs into CDMA standard-based transmitter testers. The application provides fast RF conformance measurements to help you speed up manufacturing of your IS-95 or cdmaOne and cdma2000 devices.

The cdma2000/cdmaOne measurement application is just one in a common library of 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 also include a unique “Resource Manager” that provides direct access to PXI VSA hardware drivers for the fastest power and spectrum-based measurements, while simul-taneously using the X-Series applications for fast modulation quality measurements and the 89600 VSA for fast spectrum measurements.

cdma2000 Technology Overview

cdma2000 is one of the wireless transmission format tech­nologies that meets the IMT-2000 requirements for a Third Generation (3G) global wireless communications system. It uses direct sequence modulation with digital codes to spread its spectrum. cdma2000, also known as IMT–CDMA Multi-Carrier or 1xRTT (Single-Carrier Radio Transmission Technology), is derived from IS-95. The IS-95A revision was first published in May 1993 as a solution for voice com­munication. The IS-95B revision standard can support a data rate of up to 115 kbps by bundling up to eight channels. The IS-95A and IS-95B are combined into the cdmaOne family. cdma2000 1x (IS-2000) incorporates a number of improve­ments that result in roughly twice the spectral efficiency of IS-95. It supports circuit-switched voice communications as well as a packet data rate up to 307 kbps in a single 1.25 MHz channel for low-speed mobility, and up to 2 Mbps for fixed installations.

Key Specifications

Definitions

• Specifications describe the performance of parameters covered by the product warranty.
• 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. These values are not covered by the product warranty.
• Typical values are designated with the abbreviation "typ". These are performance beyond specification that 80% of the units exhibit with a 95% confidence. These values are not covered by the product warranty.
• 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, but is not covered by the product warranty.
