Abstract: A coaxial RF switching matrix includes a plurality of switch modules arranged on both sides of a base plate and interconnected with each other through the base plate. The switch modules have four ports and a switch for alternate connections of a first port to a third port or a fourth port and a second port to the fourth or third port. The coaxial RF switching matrix also includes a base plate having a first side and a second side with a first group of switch modules attached to the first side of the base plate and a second group of switch modules is attached to the second side of the base plate such that at least one switch module of the first group of switch modules is connected through the base plate to at least one switch module of the second group of switch modules.

Abstract: An arrangement for calibrating a vector network analyzer (VNA) is substantially secure against operating errors and offers cost-effective calibration by connecting calibration components. Each calibration component includes a transponder and a non-volatile memory which contains, as non-changeable data, at least the type of the component and an individual identification number and, as changeable data, at least the number of calibration processes performed with this calibration component. The VNA includes a wireless interface for reading at least the non-changeable data of a respective calibration component and for incrementing the stored number of the calibration processes performed with this calibration component.

Abstract: The present invention concerns a device for dismantling vehicles, in particular for draining the latter. The device comprises, on pillars (30), a framework on which the vehicles are placed and inspection-type work platforms (40, 50, 60, 80, 90) which can optionally be pivoted to the side. At least one tank-emptying module and/or at least one liquid-collection module and/or at least one liquid-extraction module are provided on the framework.
