    摘要： The invention relates to a method for measuring objects (DUT) for measurement, by means of a network analyser (NA) with several measurement ports (P1-P3), at least one signal generator (GNl, GN2, GN3), for stimulating the object (DUT) for measurement and at least one local oscillator (LO), for measurement of the signal transmitted or reflected from the object (DUT) for measurement by the superposition principle. According to the invention, on a frequency change, only the frequency of the local oscillator (LO) or the frequency of the signal generator (GNl, Gn2 , GN3) is changed but not the frequency of the local oscillator (LO) and the signal generator (Fl) simultaneously.

    摘要： The invention relates to an apparatus for the phase synchronisation of several devices, wherein one device is the master device and the other devices are slave devices, with a phase synchronisation unit (30) for every device, each of which has: a first controlled oscillator (39) for producing a master reference signal (REF), a first phase detector (33) which, in order to control the first oscillator (39), compares the phase of a first comparison signal (Vl) derived from the master reference signal (REF) with the phase of a second comparison signal (V2) derived from an auxiliary reference signal (REF_IN) if the device is itself the master device, and a second phase detector (38) which, in order to control the first oscillator (39), compares the phase of a third comparison signal (V3) derived from the master reference signal (REF) with the phase of a reference signal (CASC_REF) coming from the phase synchronisation unit (30) of the master device if the device is not itself the master device but a slave device.

    摘要： A method for operating a measuring device, particularly a vectorial network analyzer, which can be connected to an object to be measured via at least two gates, comprising a number of excitation units each assigned to a gate, each excitation unit having a signal generator with which the assigned gate can be subjected to the action of an excitation signal. The inventive method comprises the following steps: measuring the actual phase offset (Δφactual) between the excitation signals, which are output on the gates, at measuring points, and; changing the frequency of at least one of the two signal generators during a correction time interval (Tcorr) so that a predetermined set phase offset (Δφset) is obtained at reference points between the excitation signals output on the gates.

    摘要： The invention relates to a frequency synthesiser which functions on the principle of fractional frequency synthesis. It consists of an integral frequency divider which can be regulated, and a control device in which a desired broken fractional ratio of the frequency divider can be regulated as a digital value. An adjustment value is produced in the control circuit by integration; said value is added to the integral part of the fractional division ratio. The value is used to regulate the integral division ratio of the frequency divider, so that a fractional division ratio corresponding to the desired fractional division ratio can be simulated. An IIR-low pass filter is used as a first or higher class integrator. The integration value generated at the outlet of the IIR-filter is reinjected as an adjustment value, while the fractional part is transferred to the fractionated part of the filter.
