Integrated Vector Signal Generator And Analyzer Expedites Wireless Testing
Separate individual vector signal analyzers and vector signal generators make up the usual test setup for cell phones and other wireless products. Aeroflex, though, has put both units into the 7000 series vector analyzer generator (VAG). This fully integrated RF parametric test system is designed for RF testing of wireless components and subsystems. ...
Signal And Spectrum Analyzer Offers New Functions
Equipped with the company’s FSV-K70 vector signal analyzer application, the Rohde & Schwarz FSV signal and spectrum analyzer demodulates digitally modulated signals down to the bit level. This option addresses users in development and manufacturing who work with digitally modulated RF signals....
Oscilloscopes Support MIDI D-PHY Standard
The DPO7000 series of oscilloscopes from Tektronix Inc. now supports the Mobile Industry Processor Interface (MIPI) D-PHY standard. These devices also now include UART/RS-232 protocol analysis software as well as four passive probes and three analysis tools as part of their standard configurations. ...
Fast RF Vector Signal Generator Speeds Cellular And Wireless Testing
Speed is a major issue for design verification testing and especially for production testing. Shorter test times reduce time-to-market and can greatly reduce production testing time as well as costs. Keithley Instruments designed its 2920A vector signal generator with speed in mind....
AWG Series Offers Up To 24 Gsamples/s
The AWG7000B series arbitrary waveform generators (AWGs) from Tektronix provide up to 24 Gsamples/s and 10-bit vertical resolution. According to the company, this performance delivers the industry’s best signal stimulus solution for ever-increasing measurement challenges....
Handheld Analyzers Speed And Simplify Wireless Field Testing
Anritsu’s E platform handheld analyzers make it easier for techs and engineers who service basestations to provision new equipment, search for problems that cause dropped calls, or perform routine antenna and line maintenance. The Site Master, Spectrum Master, Cell Master, and BTS Master also can reduce costs and test times. ...
Test Set Adds cdma2000 PESQ Measurement Functionality
Agilent Technologies has added cdma2000 perceptual evaluation of speech quality (PESQ) measurement functionality to its 8960 wireless communications test set. With this capability, the company says, wireless engineers can enhance the end-user experience by providing an objective measurement of audio quality in digitally vocoded voice. ...
Low-Cost PXI Digitizer Promises Superior Performance For Automated Wireless Test
National Instruments and Tektronix have developed a high-speed PXI digitizer that offers a 3-GHz bandwith with a sample rate beyond 10 Gsamples/s and data throughput of more than 600 Mbytes. It also includes two channels per module and can synchronize up to 100 channels or more....
Test Platform Series Enhances Capabilities Of 2G And 3G Wireless Testing
Aeroflex has released the PXI 3000 series modular test platform with supplementary communications standards, designed to allow communications test engineers to concentrate on a range of 2G and 3G wireless data standards using a single, flexible, software-defined system, according to the company. Aeroflex believes its addition of the new Bluetooth measurement suite and WLAN, CDMA2000/1xEVDO plug-ins for the PXI Studio software application and upgraded WiMAX, UMTS, and GSM/EDGE enhance the system’s versatility....
Rugged Field Device Offers Interference Analyzer Option
The FieldFox RF analyzer from Agilent Technologies now offers an interference analyzer option as well as new spectrum-analyzer features. According to Agilent, the FieldFox’s 1.5-update/s speed is the world’s fastest in the 20-MHz span and 3-kHz resolution bandwidth....
3GPP-LTE Performance Research
Agilent Technology will provide grants and test instruments to Southeast University in China to support the school’s research into higher data rates and high-quality services with increased spectrum and power efficiency for systems based on the 3GPP-LTE standard....
Multicom Test System Reduces Test Time By 75%
The IQ2010 Multicom Test System by LitePoint Corp. can test six wireless standards and perform several tests simultaneously. According to LitePoint, the system is designed to be cost-efficient and quick, while delivering quality products and test coverage....
Updated Software Tests For Signal Integrity, Power Integrity, And EMC
Version 4.0 of the Ansoft SIwave software from Ansys includes new features for signal-integrity, power-integrity, and electromagnetic-compatibility (EMC) testing. Its improved desktop graphical user interface (GUI) includes new post-processing of results....
Test System Supports DC-HSDPA
The TM500 from Aeroflex now supports the 3GPP W-CDMA Release 8 DC-HSDPA feature. DC-HSDPA extends the resource utilization and spectrum efficiency of existing W-CDMA networks by providing an alternative method to HSPA+ to increase peak data rates in the downlink to a maximum of 42 Mbits/s....
Scopes Provide Big Screen For Broad Measurement
The six models in the Infiniium 9000 series of mixed-signal and digital oscilloscopes offer the broadest measurement capability with true analog bandwidths up to 4 GHz, impressive scope performance, and built-in logic and protocol analysis, according to the company....
