    摘要: A system and method are disclosed for synchronizing timing for a terminal in a satellite communication system. Upon detecting a service interruption, first timing markers are extrapolated from timing information received prior to the service interruption. Second timing markers are also extrapolated from timing information received subsequent to the service interruption. Timing for the terminal is then synchronized with the gateway based on a timing difference between the first timing markers and the second timing markers.

    摘要: A system for measuring electromagnetic radiation, including at least one light source; a quantum converter arranged to be exposed to radiation emitted by the at least one light source and the electromagnetic radiation, and at least one detector for detecting optical radiation received from the quantum converter. The quantum converter includes at least a first interaction zone and a second interaction zone, and the system establishes at least a first light beam path for exposing the first interaction zone and a second light beam path for exposing the second interaction zone with radiation emitted by the at least one light source. Each laser beam path is controllable to be in an activated state enabling exposure and in a deactivated state preventing exposure of the respective interaction zone.

    摘要: A measuring device for measuring a signal of interest within a measuring signal is provided. It device comprises a trace determiner, which is adapted to consecutively determine a first stack of traces of the measuring signal, a statistics evaluator, adapted to, after each trace of said first stack of traces is determined by the trace determiner, statistically evaluate if a presence of the signal of interest is detected with a first pre-set degree of certainty, wherein the trace determiner is adapted to cease determining said traces of said first stack of traces, when the statistics evaluator has determined that the signal of interest has been detected to the first pre-set degree of certainty. Preferably a parameter determiner is, adapted to determine measuring parameters, based upon the statistical evaluation.

    摘要: A high bandwidth differential test probe for measuring a device under test is provided. The test probe comprises a first probe tip arranged at a first coaxial connector relative to a first rotational axis, and a second probe tip arranged at a second coaxial connector relative to a second rotational axis. For adjusting the distance between the first probe tip and the second probe tip, the first coaxial connector is rotatable with respect to the first rotational axis and the second coaxial connector is rotatable with respect to the second rotational axis. Additionally, a tilt angle between the first probe tip and a plane comprising both the first and second rotational axes, and a tilt angle between the second probe tip and the plane, is not equal to zero.

    摘要: A radar target simulation device for testing a device under test with respect to at least one radar scenario. The radar target simulation device includes a memory, a radar scenario simulator and at least two antennas. The memory stores the radar scenario(s) with respect to the device under test, and provides the radar scenario(s) to the radar scenario simulator. The radar scenario simulator receives radar signals from the device under test via the antennas to simulate the radar scenario(s) by manipulating the radar signals according to the radar scenario(s), generates resulting manipulated radar signals, and transmits the manipulated radar signals to the device under test via the antennas. The memory contains storage contents including storage cells, wherein each storage cell corresponds to the respective antenna of the at least two antennas.
