摘要： A system and method are provided which enhance the robustness of non-reliable protocols, such as UDP. As described further below, according to at least one embodiment, a method is provided for improving the robustness of using non-reliable protocols, such as UDP, in applications in which small numbers of time-critical packets are transmitted. For instance, in a system of cooperating devices on a network, a device on a network may broadcast information about itself to the other devices. According to various embodiments described below, a combination of redundant re-transmissions of non-reliable protocol data packets and inclusion of timestamps in the non-reliable protocol data packets is used to improve the robustness of applications that rely on the non-reliable protocol data packets.

摘要： A system and method synchronize operations of a plurality of devices via messages over a communication network. A plurality of devices are communicatively coupled via a communication network, and the devices have their local clocks synchronized to a high degree of precision a technique, such as IEEE 1588, for synchronizing their local clocks. Event messages can be sent that include an identification of an event, as well as a timestamp that is based on the local clock of the sender. The recipient of an event message determines if it is configured to act on the identified event, and if so it takes its action based on the timestamp included in the event message. In certain embodiments, the events that are to trigger an action and/or the specific responsive actions to be taken for a given event are dynamically programmable for each device.

摘要： A system and method are provided which coordinate the actions of a plurality of devices via scheduling occurrence of the actions based on synchronized local clocks of the devices. Thus, a plurality of devices are communicatively coupled via a communication network, and the devices have their local clocks synchronized to a high degree of precision, using IEEE 1588, NTP, or some other technique for synchronizing their local clocks. “Time bombs” can be scheduled on the devices to coordinate the occurrence of actions between the devices in accordance with the detonation times set for the respective time bombs. In certain embodiments, not only the detonation time, but also the respective action to be triggered upon detonation is programmable for each device. The time bombs implemented on the various devices can be used to coordinate the operations of the various devices with a high degree of temporal precision.

摘要： A system and method are provided which add, via an add-on module, synchronization functionality to an instrument that does not otherwise support such synchronization functionality. Various synchronization techniques may be supported by the synchronization module. For instance, in certain embodiments the synchronization module supports message-based synchronization techniques and/or time-based synchronization techniques. Accordingly, in certain embodiments, the add-on module supports synchronization with another device (e.g., another instrument or another add-on module coupled to an instrument) via synchronized local clocks (e.g., IEEE 1588) and messaging over a communication network. In certain embodiments, the add-on module additionally or alternatively supports the use of “time bombs” to trigger scheduled actions on the instrument with which the synchronization module is interfaced.

摘要： A method of determining a measurement uncertainty of a test system uses a test system model having a plurality of uncertainty terms entered into a simulator. The test system model is run on the simulator a sufficient number of iterations while randomly varying each of a first portion of the plurality of uncertainty terms within probability distributions to produce a statistically significant number of results of a selected parameter. The results are evaluated to determine a measurement uncertainty of the selected parameter.
