  • Publication number: 20220179044
    Abstract: An apparatus is for generating an emulated radar reflection signal of a target moving at a relative velocity. The apparatus includes a radar detector, an emulation transmitter, and a processor. The radar detector is configured to detect radar chirps emitted by a device under test (DUT), where the chirps are emitted at random time intervals. The emulation transmitter is configured to generate emulated radar reflection signals of the target being emulated. The processor is configured to generate control signals at intervals corresponding to the random time intervals at which the radar chirps are emitted by the DUT, where each control signal controls the emulation transmitter to generate a radar reflection signal. A relative phase of the control signals is adjusted according to a duration of each of the random time intervals between successive chirps and a magnitude and sign of the relative velocity of the target.

  • Patent number: 8984083
    Abstract: Capability to record relevant aggregated data via a test and measurement instrument interface through a software agent. The agent resides within the test and measurement instrument and gathers the information when activated. The information can be measurement data; measurement setup parameters; test system topology; user notes, brief descriptions, audio recordings or pen input; pictures; or attached documents. The agent can communicate directly to an electronic laboratory notebook server or can store the information on a portable computer readable media (CRM). A user can upload the information from the portable CRM to the server. The user can access the information via a PC workstation.

  • Patent number: 8325767
    Abstract: A system includes at least two IEEE 1588 nodes. The nodes are connected by two paths: a low latency communication path and a high bandwidth path. The clocks within the nodes are synchronized to one another at a network interface. Data and timing are transmitted on the high bandwidth path while critical timing signals are passed on the low latency communication path thereby improving timing synchronization.

  • Patent number: 7573914
    Abstract: By equipping receiving devices in a network with synchronizable clocks it is possible to periodically send an “impulse” signal that is received by all of the clocks at the same (or relatively the same) instant of time. The accuracy of the impulse clock need not be high, only that its signal reach all the clocks approximately at the same time. In one embodiment, a transmitting device, upon receipt of the synchronizing impulse signal, sends a packet of data bearing the sending device's epoch time-stamp to a receiving device. The data packet makes its way through the network element to the receiving device and the time-stamp is used by the receiving device to calculate the difference between the epoch time of the receiver and the epoch time of the sender. Effectively, this procedure removes the unknown network element transit times from the equation and allows the devices to operate in a synchronized manner.

  • Patent number: 7437486
    Abstract: A measurement device having a configurable measurement interface that enables the dynamic allocation of responsibilities among front-end and back-end subsystems of a measurement device. A measurement device according to the present teachings includes a front-end subsystem for performing an interaction with a physical environment and back-end subsystem having a set of resources for supporting the front-end subsystem. The front-end and back-end subsystems are coupled to and communicate through a measurement interface. The front-end subsystem transfers a set of bootstrap information via the measurement interface to the back-end subsystem and in response the back-end subsystem configures the resources to support the front-end subsystem.

  • Patent number: 7343266
    Abstract: A system and method of verifying metadata in a measurement processing system is described. Each combination of metadata is associated with a key, and the keys are used to verify that operations performed using the measurements are valid based on the metadata of the respective measurements. Embodiments allow metadata verification to be made prior to operating on measurements. Embodiments also minimize the processing that results from making such checks redundantly causing slowdown in the measurement processing.
