Abstract: In a method for the excitation of port groups of a multi-port device under test with coherent incident waves of the same frequency, which provide defined amplitude ratios and phase differences within each port group, the waves are generated respectively by one signal generator of a vectorial network analyzer per test port. The network analyzer has unbalanced test ports. A system-error correction of the unbalanced incident and reflected waves with reference to the ports of the device under test is implemented in order to obtain corrected waves. The amplitude and phase changes required in the signal generators to fulfill the desired amplitude and phase conditions are calculated from these corrected waves.

Abstract: A high-power radiation module has thermal protection made of inorganic, oxidic material arranged between the radiator and housing. The thermal protection is made of an essentially fiber-free material that is optically inhomogeneous with respect to IR radiation and/or UV radiation The high-power radiation module has a power per unit contact area of at least 200 kW/m2. The use of a radiation module and a method for the production of a radiation module include radiators or radiation units connected electrically and held mechanically in a housing having an outlet opening for the emitted radiation.

Abstract: For measuring electronic devices under test with a network analyzer, the electronic devices to be embedded into a linear auxiliary network during their operation, as well as, during the measurement. First, system error correction data is determined for the network analyzer according to a known calibration method by connecting calibration standards. Then, the characteristic data for the auxiliary network to be used is determined and is linked with the system error correction data to form new error correction simulation data. Finally, in the subsequent measurement of devices under test connected to the network analyzer, this error correction simulation data is appropriately considered with the algorithm for system error correction that is present in the network analyzer, so that an auxiliary network virtually connected to the device under test is simulated.

Abstract: A sulphidized catalyst which contains platinum on activated carbon is described. The activity of the catalyst can be greatly improved, while retaining the same selectivity, when the platinum-containing impregnation solution contains an oxidizing agent.

Abstract: A hollow body which has a flexible envelope and can be pressurized from inside by a pressure medium, the envelope consisting of a foam material, preferably neoprene, with closed cavities whose volume can be altered by changes in the pressure medium to correspondingly alter the thermal insulation capacity of the envelope. A coating may be applied to the foam material on the outside of the hollow body to enhance the stability of its shape when inflated.
