摘要： A method for minimizing center frequency shift and linearity errors encountered in YIG filters, comprising the following steps: automatically generating data packages in test unit depending on the user request or containing all filter characteristic states and transmitting them to the driver circuit, adjusting the desired voltage level by means of the digital to analog converters contained in the structure of the data packages received by the driver circuit, and transmitting the adjusted voltage level to the YIG filter, measuring filter characteristics (scattering parameters) corresponding to the data packages transmitted to the YIG filter in the analyser, in order to calculate the center frequency shift of the filter, determining the center frequency and linearity calculations, and recording the characteristic features measured by the analyser in the test unit.

摘要： A waveform data acquisition module acquires the waveforms of electrical signals for multiple channels. A memory controller continuously writes a digital signal S3 to one from among a first memory unit and a second memory unit. When a given memory unit has become full, the memory controller notifies an external higher-level controller that the corresponding memory unit is full and switches the wiring target to the other memory unit.

摘要： Disclosed is a linearly moveable sliding contact element having a transport device. Linearly moveable sliding contact elements of this type having a transport device are required to electrically contact conductor paths of circuit boards with one another, the circuit boards being oriented in parallel with one another and arranged above one another. In addition, the sliding contact element is arranged on a spindle of the transport device having an outer thread. Via a rotation of the transport device, the sliding contact element can be moved in a linear manner along the spindle by the outer thread. A first bearing and a second bearing are provided at the ends of the spindle. The bearings permit a mounting of the transport device between two circuit boards arranged in parallel with one another.

摘要： An integrated circuit includes a Built-In Self-Test (BIST) circuit, a predetermined signature pattern and a Read Only Memory (ROM), wherein the predetermined signature pattern is stored in the integrated circuit. The ROM stores at least effective information and a BIST signature adjustment code, the BIST signature adjustment code is irrelevant to any functional information stored in the ROM; wherein the BIST circuit is used to test content stored in the ROM to generate a signature pattern, and compare the signature pattern with the predetermined signature pattern to judge if the content stored in the ROM has error.

摘要： The invention relates to a method and to a switching device (4) and a measurement system (1). In the method according to the invention for determining time differences between measurement signals measured by at least two couple measurement devices (2, 3), a time basis signal is first generated for the measurement devices (2, 3). A common reference signal is further generated by a signal generator (5). The common reference signal is fed to measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) via the switching device (4). A measurement signal is then fed to said measurement signal inputs (8, 9) of the coupled measuring devices (2, 3) and the time position of the measurement signals relative to the reference signal is determined in each of the coupled measuring devices (2, 3). The switching device (4), to this end, has a first measuring device connection (12) and a second measuring device connection (13) connected to the measurement signal inputs (8, 9) of the first measuring device (2) and the second measuring device (3). A reference signal is alternately fed via the measuring device connections (12, 13) of the switching device (4) to the first or the second measuring device (2, 3) by connecting the first measuring device connection (12) to the reference signal input (22) or a first measuring connection (14), or by connecting the second measuring device connection (13) to the reference signal input (22) or the second measuring connection (15).
