cdma2000 Measurement Application

The cdma2000 measurement application transforms the X-Series signal analyzers into CDMA standard-based transmitter testers. The application provides fast one-button RF conformance measurements to help you design, evaluate, and manufacture your IS-95 or cdmaOne and cdma2000 devices. The cdma2000 measurement application is just one in a common library of more than 25 measurement applications in the Keysight Technologies, Inc. X-Series, an evolutionary approach to signal analysis that spans instrumentation, measurements and software. The X-Series analyzers, with upgradable 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 to you 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.

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.

cdma2000 Transmitter Tests

With the X-Series signal analyzers and the cdma2000 measurement application, you can perform RF transmitter measurements on base station and user equipment devices in time, frequency and modulation domains. Measure basic IS-95 or cdmaOne signals as well as cdma2000 signals with all radio configurations in SR1. 

Standard-based RF transmitter tests 

The latest RF transmitter test requirements for cdma2000 are defined in 3GPP2 C.S0010-D(BTS) and 3GPP2 C.S0011-C (MS) of the 3GPP2 standard. Table 2 shows the 3GPP2 required BTS RF transmitter tests along with the corresponding measurements available in the X-Series and 89600 VSA software cdma2000 applications.

Measurement details 

All of the RF transmitter measurements as defined by the 3GPP2 standard, as well as a wide range of additional measurements and analysis tools, are available with a press of a button (Table 3). These measurements are fully-remote controllable via the IEC/IEEE bus, GPIB or LAN, using SCPI commands. Analog baseband measurements are available on the PXA or MXA signal analyzer with BBIQ hardware. Supported baseband measurements include all of the modulation quality pus I/Q waveform measurements.

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
• PXA specifications apply to analyzers with frequency options of 526 and lower. For analyzers with higher frequency options, specifications are not warranted but performance will nominally be close to that shown in this section
