摘要： The invention relates to a method for carrying out a frequency change whilst retaining the phase relationship between several devices, in particular, network analyzers. Each device has at least one signal generator for stimulating an object for measurement and at least one local oscillator, connected to at least one mixer, for receiving a measuring signal obtained from the object for measurement by the superposition principle. On changing frequency, in a first step, only the frequency of the local oscillators of all devices is changed and the frequency of the signal generators of all devices remains unchanged. In a second step, only the frequency of at least one signal generator is changed and the frequency of the local oscillators of all devices remains unchanged.

摘要： A signal measuring device controls the width of a signal for controlling frequency sweep, in accordance with a signal to be measured. The signal measuring device includes a local oscillator (10) for generating a local signal, a mixer (12) for mixing a signal to be measured with the local signal; a frequency sweep section (14) for sweeping the frequency of the local signal, and a sweep control section (30) for terminating the sweep when the presence section of the signal to be measured has terminated. The signal to be measured is a carrier in a burst and the spectrum of the carrier is to be measured. The width of the presence section of the signal to be measured may be changed. Even if changed, it is possible to control the width of the signal for controlling the frequency sweep, in accordance with the signal to be measured since the sweep is terminated when the presence section of the signal to be measured has terminated.

摘要： An analysis operation section uses a digital signal converted by an A/D converter, and performs frequency analysis for a modulation signal and modulation analysis for the modulation signal selected by a signal selection circuit in order to modulate/analyze a digital signal level of the modulation signal as an analysis object outputted from a level converter. A controller instructs the analysis operation section to execute an analysis instruction inputted via an operation input section, sends a selection instruction to the signal selection circuit in accordance with a modulation type of the inputted modulation signal, and sets a bandwidth of an RBW filter in accordance with the modulation type when the modulation signal having a band limited by the RBW filter is selected as the modulation signal inputted to the A/D converter, and the modulation analysis instruction is inputted.

摘要： A sweep controller supplies a current to a YTO(YIG-Yttrium-Iron-Garnet Tuned Oscillator) from a current drive circuit in such a manner that frequencies corresponding to a first range in an oscillation frequency of the YTO designated as a desired frequency range for analysis with one sweep, and a second range designated as a frequency range higher than the first range for the analysis with the next one sweep are oscillated by the YTO. Moreover, the sweep controller outputs an instruction for increasing the current flowing through the YTO from the current drive circuit over a part of a period between an end of the first range and a start of the second range in order to shorten the period between the end of the first range and the start of the second range when it is detected that a difference between an end frequency of the first range and a start frequency of the second range is larger than a predetermined frequency difference.

The spectrum analyzer includes at least two measurement channels, each of the measurement channels has a frequency mixer, a local oscillator and an IF (intermediate frequency) filter for mixing an input signal to be measured with a local signal of the local oscillator to produce an IF signal which passes through the IF filter, and a demodulator provided in one of the measurement channels to demodulate the IF signal produced from the input signal to generate a trigger signal to start an operation of the other measurement channel.

摘要： The object of a spectrum analyzer of present invention is to increase a frequency stability and SPAN probability. A voltage control oscillator is rendered to a locked state based on a frequency as a reference frequency output from a direct digital synthesizer. Thereafter, the voltage control oscillator performs a sweep operation for a signal output therefrom, based on a frequency error to which a ramp signal is added by an adder, that is, based on the reference frequency output from the direct digital synthesizer.
