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.

Port multiplier and radio communication test system

A coupler, in particular a resistive coupler, wherein all ports are at least partially or completely arranged in or at a connector. The coupler comprises resistors which are adapted to sum and/or divide the incoming and/or outgoing signal. The resistors are arranged at or in the connector. A sum port and/or at least two dividing ports are arranged on a substrate.

Wideband coupler

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.

Mobile radio testing device and method for protocol testing

An RF cable includes a connector housing having an RF signal output interface, a cable body having a first end portion connected to the connector housing and a second end portion comprising an RF signal input interface, an RF signal transmission path formed from the RF signal input interface through the cable body and the connector housing to the RF signal output interface, and a power measurement device integrated into the connector housing and configured to measure a power value of an RF signal transmitted through the RF signal transmission path. The RF cable further includes a measurement signal output interface, and a measurement signal transmission line connecting the power measurement device to the measurement signal output interface, the power measurement device being configured to output a measurement signal indicating the measured power value of the RF signal at the measurement signal output interface.

RF cable and cable-bound path loss determination method

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.
