Abstract: The invention relates to a suction device (12) comprising a valve housing (18), a flexible partition wall (28) which runs in such a way that a control space (30) extends on one side and an intake side (21) lies on the other side, wherein the control space (30) is connected to the intake side (21) via a throttle passage (38), wherein the throttle passage (38) is formed in such a way that a flow resistance for flows is defined by the throttle passage (38) in such a way that, in the case of free suction, a negative pressure in relation to the intake side occurs in the control space (30) on account of the flow resistance.

Abstract: An automated test equipment for testing a device under test includes a control unit and a plurality of tester subunits. The control unit is configured to put the tester subunits in a state of lower activity in dependence on a current demand on the test resources.

Abstract: A calibration module for a tester, for testing a device under test, includes a pair of RF-channel terminals, a calibration device, a pair of measurement terminals and a mode selector. The pair of RF-channels terminals is configured to send or receive measurement signals to or from an RF-channel of the tester. The calibration device is configured to perform a calibration of the RF-channel based on the measurement signals sent to, or received from, the RF-channel. The pair of measurement terminals is configured to send or receive measurement signals to or from the device under test. The mode selector is configured to connect, in a calibration phase, the pair or RF-channel terminals to the calibration device for calibrating the RF-channel and to connect, in a measurement phase, the pair of RF-channel terminals to the pair of measurement terminals for routing measurement signals from the RF-channel to the device under test or vice versa.
