W-CDMA/HSPA+ Modulation Analysis

The flexible Keysight Technologies, Inc. 89600 vector signal analysis software (VSA) with option 89601B7NC for 3G bundle provides W-CDMA (3GPP) and enhanced HSPA modulation analysis for the R&D designer engineer. It includes descrambling, despreading, and demodulation of W-CDMA and HSPA+ uplink and downlink signals, including 2-channel MIMO.

W-CDMA/HSPA+ is just one of over 70 signal standards and modulation types for which the 89600 VSA can create a window into what’s happening inside your complex wireless devices. Our VSA tools provide views of virtually every facet of a problem, helping you see the “why?” behind signal problems. Whether you’re working with emerging or established standards, Keysight’s industry-leading VSA software helps you see through the complexity

W-CDMA/HSPA+ overview

W-CDMA, also called UMTS, is a 3GPP format that transmits using frequency domain duplexing in 5 MHz channels. It has been updated with HSDPA and HSUPA (or, collectively, HSPA) and further enhanced to support Evolved High Speed Packet Access, or HSPA+. HSPA+ increased the uplink and downlink performance by using MIMO techniques and enhanced modulation schemes, such as 64 QAM, to provide up to 56 Mb/s downlink and 22 Mb/s uplink data rates.

Analysis and Troubleshooting

Make CDE and CDP measurements on a single code domain layer or composite code domain signal

Troubleshoot signal and power control quality with code domain error and code domain power measurements. The analyzer automatically identifies all active channels regardless of the symbol rate or spread code-length. View one layer at a time and determine the behavior of specific layers and channels with single-layer CDP and CDE displays. Composite CDP and CDE displays present all code layers at a time to help you understand the overall signal performance.

Descramble, despread, and demodulate your downlink or uplink signals for troubleshooting

Choose from a wide range of error measurements such as EVM, IQ error analysis, or statistical performance data. View detailed measurements of the despread signal from a single code channel, within a given code layer.

See multiple views of your signal

Option B7U provides signal and error information prior to demodulation, or by specific code layer, or single code channel, within a code layer. You can also look at a composite view of all code layers and code channels simultaneously, cross channel measurements, or MIMO metrics. All of these views are designed to help you understand every detail of your signal and investigate all anomalies.

Easily set up your measurements

Flexible measurement setup provides automatic or manual modulation detection of all supported formats, including HS-PDSCH channels using QPSK, 16 QAM, 64 QAM, and E-DPDCH channels using BPSK or 4 PAM. Predefined Test Models 5 and 6 are also included.

Use supported Keysight hardware to perform 2-channel HSPA+ MIMO signal measurement analysis

Option B7U supports 2x2 DL MIMO analysis for HS-PDSCH signals. Single-channel analysis measurements for each channel are also available when using single-input hardware.

Capture and analyze signals

The 89600B VSA includes signal capture and playback capabilities. Use it to capture burst and transient signals for analysis. Take advantage of tools like overlap processing for detailed “slow motion” analysis and the spectrogram and cumulative history traces for evaluating the dynamic frequency and amplitude behavior of your signal over time.

Choosing between 89600 VSA software and X-Series measurement applications

89600 VSA is the industry-leading measurement software for evaluating and troubleshooting wireless signals in R&D. PC-based, supporting numerous measurement platforms, the 89600B provides the flexibility and sophisticated measurement tools essential to finding and fixing signal problems. X-Series advanced measurement applications provide embedded format-specific, one-button measurements for X-Series analyzers. With fast measurement speed, pass/fail testing, and simplicity of operation, these applications are ideally suited for design verification and manufacturing.
