Embodiment Construction

[0021] The embodiment of the present invention provides a vector signal analyzer, which divides the received signal into at least two channels through the radio frequency front-end branching module, and performs radio frequency / microwave processing and analog-to-digital conversion on each channel of the signal, and then performs digital signal processing The module performs spectrum analysis or signal demodulation analysis on each signal, so as to realize the function of spectrum measurement and signal demodulation analysis at the same time.

[0022] Such as figure 2 As shown, the vector signal analyzer provided by the embodiment of the present invention includes:

[0023] The RF front-end splitting module 201 is used to divide the received signal into at least two identical signals;

[0024] An analog signal processing module 202, configured to perform radio frequency / microwave processing and analog-to-digital conversion on each signal;

[0025] The digital signal processi...

Abstract

The invention discloses a vector signal analyzer, relating to the communication technology. The vector signal analyzer comprises that: a radio frequency front splitting module used for dividing received signals into at least two paths of same signals; an analog signal processing module used for carrying out radio frequency / microwave processing and analog-to-digital conversion on each path of the signals; a digital signal processing module used for respectively carrying out spectrum analysis and signal demodulation analysis on each path of digital signals output by the analog signal processing unit. According to an embodiment of the invention, the radio frequency front splitting module divides the received signals into at least two paths, and carries out radio frequency / microwave processing and analog-to-digital conversion on each path of the signals, the digital signal processing module respectively carries out spectrum analysis and signal demodulation analysis on each path of the digital signals, thus a frequency spectrum measuring function and a signal demodulation analysis function are carried out simultaneously, synchronism of each analysis result is good, and comparison and analysis by operation personnel are facilitated.

Description

technical field [0001] The invention relates to communication technology, in particular to a vector signal analyzer. Background technique [0002] At present, vector signal analyzers for signal analysis generally have spectrum analysis functions and signal demodulation analysis functions, but since a general vector signal analyzer has only one receiver, it can only perform spectrum analysis functions or signal demodulation analysis functions at the same time , when it is necessary to observe the spectrum of the specified frequency band at the same time, and at the same time need to observe the signal quality, that is, the signal demodulation analysis, it is necessary to use two instruments, that is, one spectrum analyzer and one vector signal analyzer or two with spectrum analyzer function The vector signal analyzer also needs more auxiliary equipment to build a test environment, which is inconvenient to use and high in cost. [0003] Specifically, such as figure 1 As show...
