摘要： An electrical utility meter having harmonic data templates advantageously enables a user to determine whether equipment at a particular site is susceptible to electrical damage or interference. According to an exemplary embodiment, the meter generates measured harmonic data for a plurality of phases in the polyphase electrical system. A user may select at least one of a plurality of predetermined templates including one or more harmonic data thresholds. Each of the predetermined templates corresponds to a condition where a specific device is susceptible to electrical damage or interference. The measured harmonic data is compared with the one or more harmonic data thresholds included in the at least one selected predetermined template. An alarm is generated when the measured harmonic data exceeds the one or more harmonic data thresholds included in the at least one selected predetermined template. According to a preferred embodiment, the alarm is generated in dependence upon the specific template whose one or more harmonic data thresholds are exceeded

摘要： The present invention, generally speaking, provides a method and apparatus for accurately measuring a communications signal. In accordance with one aspect of the invention, DC offset effects and nonlinearities attributable to a communications amplifier are made spectrally separable from DC offset effects and nonlinearities attributable to the measurement apparatus. Spectral reparability may be accomplished, for example, by adding an offset frequency to a local oscillator use by a downconverter of the measurement apparatus. As a result, the signal of interest is moved away from baseband (zero frequency) to the offset frequency. Similarly, other nonlinearities in the video amplifier (such as third order distortion) manifest themselves mostly at harmonics of the offset frequency. Hence spectral separability between the power amplifier characteristics and these nonlinear impairments of the measurement system is achieved. At the offset frequency, the signal of interest may be represented by a single signal component (e.g., the in-phase component I) instead of requiring an I/Q representation. The measurement apparatus may therefore be dramatically simplified, and errors stemming from undesired interaction of I and Q signal processing chains may be avoided. In accordance with another aspect of the invention, the effects of noise are mitigated through different averaging methods.
摘要翻译：本发明一般地提供了一种用于精确测量通信信号的方法和装置。根据本发明的一个方面，可归因于通信放大器的DC偏移效应和非线性与DC偏移效应和归因于测量装置的非线性光谱分离。光谱可修复性可以例如通过将测量装置的下变频器使用的偏移频率添加到本地振荡器来实现。结果，感兴趣的信号从基带（零频率）移动到偏移频率。类似地，视频放大器中的其他非线性（例如三阶失真）主要表现在偏移频率的谐波上。因此，实现了功率放大器特性与测量系统的这些非线性损伤之间的频谱分离性。在偏移频率下，感兴趣的信号可以由单个信号分量（例如，同相分量I）表示，而不是需要I / Q表示。因此，可以显着地简化测量装置，并且可以避免由I和Q信号处理链的不期望的相互作用引起的误差。根据本发明的另一方面，通过不同的平均方法来减轻噪声的影响。

摘要： An RF power amplifier distortion measurement system (100) measures amplitude and phase distortion of a microwave/RF power amplifier (10) by phase quadrature down-conversion (110, 140) of each of an RF amplifier's input signal (S) and amplified output signal (KS+E) to baseband in-phase (I) and quadrature (Q) components, and performing RF amplifier distortion measurements on these down-converted baseband I and Q signals. The derived error measurement signal is remodulated to RF by phase quadrature up-conversion circuitry (190) to produce an up-converted RF signal (E) that corresponds to the RF distortion component contained in the RF output signal (KS+E) produced by the RF power amplifier (10).

摘要： A location of at least one PIM source (10) within an antenna array assembly (2) is determined by applying an excitation waveform to a connection port (13), setting a multi-element phase shifter (8) to a first state to apply a respective phase shift to respective paths, and making a first measurement of at least the phase of a PIM product emitted from the connection port (13). The multi- element phase shifter (8) is then set to a succession of further states and further such measurements are made for each of the further states. From the first and further measurements a dependence is determined of at least the phase of the PIM product on the state of the multi-element phase shifter. The determined dependence is compared with a plurality of predetermined dependences (5), each predetermined dependence being for a PIM source located in a respective path between the multi-element phase shifter and a respective sub-array to determine the location within the antenna array assembly (2) of the at least one PIM source (10).

摘要： An apparatus, method and work product is disclosed. The method comprises measuring plural transmit signals and corresponding receive signals and determining, using a model describing a relation between each of the plural transmit signals and a respective passive intermodulation signal, a standardized passive intermodulation signal as one or more nth order intermodulation products for a standardized transmit signal consisting of two tones each of a power of substantially 20 Watts. The method may also comprise identifying in the model one or more n th order cross-intermodulation products resulting from three or more transmit signals having different respective carrier frequencies. Responsive to the identification, the method may comprise adapting the standardized two-tone passive intermodulation signal by determining an offset for producing an adapted two-tone standardized passive intermodulation signal, n is an odd integer greater than two.
