摘要： A method, a system, and a computer program for executing high resolution spectrum monitoring. A sensor receives an input signal having a varying frequency content over time. One or more samples of the received input signal are sampled. The samples of the received input signal include one or more swept signal samples generated by sweeping, using a center frequency of the sensor, the received input signal across an entire frequency spectrum associated with the received input signal. Sampling of the samples of the received signal is performed while performing the sweeping. The signal samples are processed.

摘要： An input signal Sx in a first millimeter-wave frequency band higher than 100 GHz is input to a millimeter-wave band filter 20 in which a pair of radio wave half mirrors 30A and 30B so as to opposite to each other and which performs a resonance operation. A signal component Sa corresponding to the resonance frequency of the filter is extracted, is mixed with a first local signal L1 with a fixed frequency, and is converted into a signal in a second frequency band. The converted signal component Sb is mixed with a second local signal L2 whose frequency is swept and is converted into a signal in a predetermined intermediate frequency band. Then, the level of the signal is detected. The millimeter-wave filter 20 has high selectivity characteristics in a frequency domain higher than 100 GHz and can change its passband center frequency.

摘要： A method and a device for increasing the dynamic range and measuring accuracy of a measuring device for spectrum and/or network analysis images a high-frequency electronic signal within a frequency range into at least two spectra through a first frequency translation by means of a mixer of the measuring device. As a result of the first frequency translation, the spectrum of the high-frequency electronic signal is successively imaged within the resolution bandwidth (ΔFZF) of an intermediate frequency filter of the measuring device. At the same time, through a second frequency translation, every spectral line of interference signals generated in the measuring device comes to be disposed outside the resolution bandwidth (ΔFZF) of the intermediate frequency filter.

摘要： A spectrum analyzer includes a synchronizing signal input terminal (27A) and a sweep control signal generator (32) inserted between the synchronizing signal input terminal (27A) and a ramp address generator (23). In the case of making a frequency analysis of an input signal Sx which is a burst wave, a synchronizing signal SY, synchronized with the burst wave, is applied to the synchronizing signal input terminal (27A) from the outside and a sweep control signal SC which rises an arbitrary period of time after the synchronizing signal SY and has an arbitrary width is generated by the sweep control signal generator (32). The sweep control signal SC is applied to the ramp address generator (32), which sweeps, in each burst, a ramp voltage VR for controlling a local oscillator (16) and an address AD for effecting a write into a signal loading memory (19), and in the other periods the sweep is stopped.
