Abstract: Systems and methods for delaying transmission of an alarm signal responsive to detecting delay actions indicative of progress towards confirming or denying the alarm signal are provided and can include an alarm processing device receiving the alarm signal and determining whether a user device is enrolled in an alarm notification service. When the user device is enrolled in the alarm notification service, the alarm processing device can transmit a notification to the user device, start a delay timer, and determine whether a first delay action associated with the user device is detected prior to expiration of the delay timer. When the first delay action is detected prior to the expiration of the delay timer, the alarm processing device can alter the delay timer consistent with a next delay action associated with the user device and, when the delay timer expires, transmit the alarm signal to the central monitoring station.

Abstract: An optical modulator that is adapted to modulate a light signal at very high RF frequencies and provide the modulating RF signal to equipment separate from the modulator is disclosed. The modulator includes a Mach-Zehnder Modulator in which light loses due to the crossing of the RF waveguide conductors and the optical waveguides are reduced. In addition, problems arising from asynchrony between the RF signals and the optical signals are reduced. The modulator also reduces signal losses due to resonances in the modulator. The modulator can be configured to be used in test probes that require a compact configuration that is adapted to designs having multiple test probes that are proximate to each other.

Abstract: A test system for testing a DUT includes a first array of probe elements located in the near field of the DUT antenna that is either mechanically translated or electrically scanned in a first direction while being electrically scanned in a second direction that is different from the first direction to sense a bounded radiation surface comprising RF signals transmitted by the DUT antenna. A test system receiver receives first near field values contained in the RF signals and inputs them to processing logic of the test system. A reference measurement apparatus of the test system detects the RF signals and obtains reference information therefrom. Processing logic of the test system uses the reference information to correct near field phase values contained in or derived from the first near field values for phase shift between the local oscillator (LO) of the DUT and the LO of the test system.

Abstract: A method determines far field EVM of a DUT using over-the-air (OTA) testing, the DUT having a transmitter/receiver and an antenna that are integrated together such that there is no connection port for interfacing a test system for directly measuring the EVM. Modulated RF signals transmitted by the DUT propagate OTA via the antenna. The method includes performing a near field scan of a bounded radiation surface, which includes measurement points at which waveforms of a repeatedly transmitted modulated RF signal are measured; downconverting the waveforms to intermediate frequency (IF), and digitizing the IF waveforms; synthesizing digital waveforms corresponding to the IF waveforms; accounting for corresponding RF propagation in the far field for the digital waveforms; providing a modulated digital IF waveform using the digital waveforms for which RF propagation has been accounted; and calculating EVM of the DUT in the far field using the modulated digital IF waveform.

Abstract: A test system for testing a DUT includes near field and intermediate field measurement devices located in a near field and an intermediate field, respectively, of the DUT antenna that sample first and second bounded radiation surfaces, respectively, comprising RF signals emitted by the DUT antenna in at least first and second directions in which the bounded radiation surfaces extend. A receiver of the test system generates first and second matrices of near field and intermediate field values, respectively, from the samples obtained by the near field and intermediate field measurement devices, respectively and inputs them to processing logic of the test system. The processing logic processes the first and second matrices of near field and intermediate field values, respectively, and derives a third matrix of near field phase values therefrom.

Abstract: Techniques for generating, storing, and using service call graphs are provided. In one technique, trace data items generated by different services are correlated to generate a service call graph. Trace data indicates when certain services are called and their respective latencies as a result of a client request. A service call graph may reflect a single trace or multiple traces over a particular period of time. A service call graph may be analyzed to inform administrators of a web site how a web application and the services it relies on are performing. A service call graph may be used to determine whether there are sufficient resources to support a projected increase in traffic to a web application. A service call graph may be used to estimate a cost of a web application. Multiple service call graphs may be compared to determine one or more root causes of a performance problem.
