Patent number: 11416430Abstract: A port multiplier for extending ports of a radio communication test instrument comprises an input for receiving at least one input signal, a power supply unit, a control logic, and at least one output for outputting a processed signal. The port multiplier is configured to split the at least one input signal into its different components such that a radio signal component of the input signal is forwarded to the at least one output. A power signal component of the input signal is forwarded to the power supply unit. Further, a control signal component of the input signal is forwarded to the control logic. Moreover, a radio communication test system for testing a device under test is described.Type: GrantFiled: February 3, 2020Date of Patent: August 16, 2022Assignee: Rohde & Schwarz GmbH & Co. KGInventors: Gottfried Holzmann, Martin Oetjen, Matthias Jelen, Albert Moser

Patent number: 11082139Abstract: A mobile radio testing device for protocol testing of a device under test is provided. The mobile radio testing device comprises a downlink path and an uplink path, wherein the uplink path comprises at least a first analysis mode and a second analysis mode. In this context, the mobile radio testing device includes a demodulation processing unit for analyzing signals from the device under test in the first analysis mode. In addition, the second analysis mode analyzes signals from the device under test without using the demodulation processing unit.Type: GrantFiled: September 30, 2019Date of Patent: August 3, 2021Assignee: 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.
