摘要： A measuring device (e.g., a vectorial network analyzer) by means of at least two ports can be connected to a device under test and has associated excitation/receiving units (ERUs), each thereof having one port. At least one ERU has a signal generator, which can apply an excitation signal onto a device under test. Each ERU possesses two receiving apparatuses (each with a mixer in connection with an oscillator signal) to receive the excitation signal, the reflected signal from the associated port or the signal transmitted to the associated port and converts said signal into an intermediate signal. Each ERU exhibits its own oscillator separate from the signal generator, and generates the oscillator signal for the mixer of the receiving apparatus of the ERU, whereby the frequency and/or phase of the oscillator signals, can be adjusted independently of the frequency and/or phase of oscillator signals of the oscillators of other ERUs.

摘要： A coupler comprises a first line and a second line in each case with two connectors. The lines run in spatial proximity and are coupled. A first connector of the first line and a first connector of the second line are disposed in spatial proximity. A second connector of the first line and a second connector of the second line are disposed in spatial proximity. A signal does not couple or couples only with a high attenuation from the first connector of the first line to the first connector of the second line. The signal is split, in particular, at the design frequency, into largely identical parts to the second connector of the first line and the second connector of the second line. The first line and the second line in this context are strip conductors.

摘要： A method for determining the place of origin of a passive intermodulation product excites a distributed device under test with two first excitation signals (x1(t),x2(t), each with a single spectral line, of which the frequencies (f1,f2) provide a frequency spacing relative to one another. Following this, the phase (φIM3Meas) of a first passive intermodulation product generated at the place of origin in the distributed device under test from the first excitation signals ((x1(t), x2(t)) by nonlinear distortion is measured, and the delay time of the first passive intermodulation product from the place of origin to the measuring device is calculated from the measured phase (x1(t),x2(t)) and the frequency (2·f1−f2) of the first passive intermodulation product. Finally, the place of origin of the passive intermodulation product is determined from the delay time and the topology of the distributed device under test.

摘要： The present disclosure provides a method and a corresponding device for extending the illumination of an object under investigation. The object under investigation is illuminated with an electromagnetic microwave signal which is transmitted from a transmission antenna. The microwave signal reflected from the object under investigation is received by at least one reception antenna. An image of the object under investigation is reconstructed through synthetic focusing of the reflected microwave signal. At least one reflector element is arranged orientated towards the object under investigation and the microwave signals reflected from the reflector element and from the object under investigation are received in a reception antenna and used for the reconstruction of the image of the object under investigation in addition to the microwave rays from a transmission antenna which strike the object under investigation without reflection on the reflector element and are received by the reception antenna without reflection on the reflector element.
