Although primarily residential, Palo Alto has aerospace, electronics, and advanced research industries. , Calif.--(BUSINESS WIRE)--Nov. 3, 2003 Most Comprehensive Wireless Signal Analysis Capability in a Single Instrument Agilent Technologies Inc. (NYSE NYSE See: New York Stock Exchange :A) today introduced a series of new capabilities for its PSA (Professional Services Automation) An information system designed to organize, track and manage all opportunities, work, resources, costs, revenues and invoices to improve the productivity and efficiency of the workforce. Series high-performance spectrum analyzers that make the instruments the first to characterize components and systems for base and mobile stations based on the TD-SCDMA TD-SCDMA Time Division Synchronous Code Division Multiple Access (time division synchronous CDMA (Code Division Multiple Access) A method for transmitting simultaneous signals over a shared portion of the spectrum. The foremost application of CDMA is the digital cellular phone technology from QUALCOMM that operates in the 800 MHz band and 1.9 GHz PCS band. ) and 1xEV-DV (1x evolution, data and voice) wireless access methods. These new capabilities, together with Agilent's existing standards-based measurement personalities, give the PSA Series the most comprehensive wireless signal analysis capabilities available in a single instrument. TD-SCDMA, the wireless access method developed in China, has the potential to double the traffic-carrying capacity of a wireless network. It uses the same frequency band for both the uplink and downlink transmission paths for greater efficiency, and can allocate resources for either one as needed as needed prn. See prn order. . It also takes advantage of smart antenna technology and can simultaneously detect multiple parallel signals. 1xEV-DV is the latest revision to the cdma2000 3G access method. It increases network capacity and data rates by allowing bandwidth to be allocated on demand, and supports voice and data traffic on the same device. Wireless network equipment manufacturers are currently conducting interoperability testing and field trials for 1xEV-DV. The TD-SCDMA measurement personality (Option 211) for the PSA Series spectrum analyzers allows designers to fully characterize the transmitted signals of TD-SCDMA base stations with a single instrument. It is equally suited to both design and development environments and has an intuitive user interface that makes the process fast and simple. The standards-based power measurements for both uplink and downlink signals include power versus time, transmit power, adjacent channel power, multi-channel power (up to 12 channels), as well as spurious emissions and spurious emissions masks. The user has numerous choices within each measurement. For example, when measuring transmit power the user can display the minimum, maximum and mean values of a single burst or complete 10-ms frame, and can select either RMS or log averaging. When using spectrum emission masks (which measure spurious emissions within specific frequency bands), the designer can simultaneously display both spectrum and tabular results. Average or peak detection can be selected, and the offset frequency, reference bandwidth and limit values can be specified. In addition, the Agilent 89601A vector signal analysis software, which includes troubleshooting tools for analyzing many types of signals, now can demodulate To isolate a data signal from a carrier wave. The demodulation circuit uses the unmodulated carrier as a reference signal and compares it to the received signal. See modulation and carrier. demodulate - demodulation TD-SCDMA signals as well. This allows the PSA Series, in combination with 89601A analysis software, to troubleshoot a broad array of modulation problems in addition to the TD-SCDMA power measurements provided by Option 211. To allow 1xEV-DV components and systems to be characterized, Agilent has created new composite rho and code-domain tests that support code-domain 8PSK (1) See preshared keys. (2) (Phase Shift Keying) A simple digital modulation technique that uses two different phase angles for 0 and 1. Quadrature PSK (QPSK) uses four phase shifts for each two bits of input. See phase modulation and DPSK. and 16QAM (1) (Quality Assessment Measurement) A system used to measure and analyze voice transmission. (2) (Quadrature Amplitude Modulation) A modulation technique that employs both phase modulation (PM) and amplitude modulation (AM). modulation techniques. The new measurement personality is available as Option 214 for the PSA Series analyzers. The 1xEV-DV measurement personality provides powerful measurements for troubleshooting many kinds of modulation. The modulation accuracy capability shows signal quality via parameters such as composite rho, error vector magnitude The error vector magnitude or EVM is a measure used to quantify the performance of a digital radio transmitter or receiver. A signal sent by an ideal transmitter or received by a receiver would have all constellation points precisely at the ideal locations, however various , frequency error and pilot offset for one-slot signal data. For more in-depth evaluation, code-domain analysis allows signal capture of up to 32 slots. In addition, symbol-based EVM EVM Earned Value Management EVM Evaluation Module EVM Error Vector Magnitude EVM Electronic Voting Machine EVM Expert Group on Vitamins and Minerals EVM Economic Value Management EVM Extraneous Vegetable Matter EVM Extra-Value Meal EVM Electronic Voltmeter with IQ symbol constellations and other results of magnitude error, phase error, and symbol power versus time trace can reveal the root cause of signal problems.
