Patent number: 10171266Abstract: A switch-extender is connected to a measurement system and to several DUTs. It splits a signal from the measurement system into several signals so that the several DUTs receive the same signal and can therefore be tested in parallel. The switch-extender further includes at least one amplifier and/or at least one attenuator for every output port so that every signal has the same signal level no matter what the individual attenuation factor of the signal connectors or of the internal printed circuit board is. Furthermore a method for calibrating the measurement system as well as for the switch-extender and the signal connectors describes how to obtain the needed calibration values both for the downlink path and for the uplink path without changing the signal connector.Type: GrantFiled: May 6, 2016Date of Patent: January 1, 2019Assignee: ROHDE & SCHWARZ GMBH & CO.

Patent number: 9445523Abstract: The invention relates to an electronic assembly comprising a plurality of electronic component groups and a cooling device for cooling the electronic component groups. The cooling device provides a cooling-power distributor. A cooling power of the cooling device can be individually controlled by the cooling-power distributor for every component group. Furthermore, the assembly provides temperature-registering means for every component group for registering a temperature of every component group, and a load-determining device for determining a parameter for every component group which describes the load experienced by a component group on the basis of the temperature registered for this component group. A control unit controls the cooling-power distributor on the basis of the parameters determined for the component groups.Type: GrantFiled: July 5, 2011Date of Patent: September 13, 2016Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 8195391Abstract: A route finding system has a map database containing node data and edge data, wherein nodes represent points on a route and edges represent the connections between the nodes. A route search system determining an optimal route according to prescribed route parameters, wherein a route comprises at least one partial route, and a partial route comprises at least one edge, considers the difficulty of the partial routes during route finding. The abilities of the user and/or a user selection determine the influence of the difficulty of the partial routes on the route obtained during route search. Difficult partial routes are characterized by the necessity of carrying out difficult maneuvers, particularly turning maneuvers and/or crossing maneuvers, to complete the partial route.Type: GrantFiled: February 20, 2008Date of Patent: June 5, 2012Assignee: Rohde & Schwarz GmbH & Co.

Patent number: 4937773Abstract: A sine-wave oscillator produces a sine-wave signal of a digitally predetermined frequency f in successive steps by only one multiplication and one addition under control by a clock generator having a clock frequency p. During a first step the value A.sub.(i+l) =A.sub.i +B.sub.i .multidot.k is determined and during a subsequent second step the value B.sub.(i+l) =B.sub.i -A.sub.(i+l) .multidot.k is determined therefrom, A.sub.(i+l) and B.sub.(i+l) being the respective newly calculated values, A.sub.i and B.sub.i being the respective previous values calculated in a preceding step, and k being a factor k=2.multidot.sin (.pi..multidot.f/p) calculated in a computer. The period of the successive steps is selected to be 1/2 p, and for the first step A.sub.(o) =0 and B.sub.(o) =cos (.pi..multidot.f/p) are selected. At least one of the two factors A.sub.(i+l) and B.sub.(i+l) is finally converted to an analog sine-wave signal in a digital-to-analog converter.Type: GrantFiled: November 3, 1988Date of Patent: June 26, 1990Assignee: Rohde & Schwarz GmbH & Co.
