Abstract: A measurement apparatus has a magnet apparatus and a sensor apparatus, which can be rotated relative to one another about an axis of rotation. To generate magnetic field measurement signals, the sensor apparatus has a number of at least three magnetic field sensors, which are arranged offset from one another by an angle of rotation, each having an output to output a magnetic field measurement signal. The outputs are connected to a first signal path, in which a transformation device for transforming the magnetic field measurement signal into a plurality of phase-shifted transformation signals is arranged, which plurality is less than the number of the magnetic field sensors. Output connectors for the transformation signals are connected to an evaluation device for generating the angle position signal. A comparator is arranged in a further signal path and is connected to the measurement signal output of a magnetic field sensor, for comparing the magnetic field measurement signal of one of the magnetic field sensors with a comparator threshold value signal. For detecting a phase error, the evaluation device has a phase position comparison element, which has a first phase position comparison element input connected to an output connector of the transformation device, and a second phase position comparison element input connected to the comparator output.

Abstract: An electronic component has an integrated circuit, a capacitor, and several conductors that are connected by way of bonding wires with contact elements of the integrated circuit. Two conductors are connected to one another by way of a current path, in which the capacitor, a first electrically conductive layer connecting a first connector of the capacitor to the first conductor, and a second electrically conductive layer connecting a second connector of the capacitor to the second conductor are arranged. The integrated circuit has an impedance measuring device to measure the impedance between the conductors that are connected to one another by way of the current path, which device can be connected to the first conductor by means of a switch. The impedance measuring device is configured to determine the equivalent ohmic series resistance between the conductors. This enables the contact quality of the layers to be tested.
