Embodiment Construction

[0011] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0013] Portable ultrashort wave frequency hopping radio performance tester, see attached figure 1 As shown, including the coupler connected to the station under test, a small part of the signal is coupled out from the signal emitted by the high-power transmitting station and sent to the RF processing module through its coupling end. The coupling degree is 50dB, which ensures that the detection instrument will not Burned out by the high-power ...

Abstract

The invention discloses a performance detector of a portable ultrashort wave frequency hopping station. The detector comprises a coupler which is connected with the station to be detected, and couplesa small part of signals which are transmitted by a high-power transmitting station to a radio frequency processing module through a coupling terminal; the a radio frequency processing module dividesa frequency range by various filters, and sends the obtained radio frequency signal frequency to a data acquisition card; the data acquisition card performs digital treatment on the obtained radio frequency signal frequency group; a control panel perfroms short time FFT transform on a baseband signal from the data acquisition card, calculates parameters, and sends the result to an external touch screen for display. Software radiotechnics is used to realize miniaturization, modularization and generalization and integrating part of functions of oscilloscopes, frequency spectrographs, modulationdomain analyzer and the like. The detector can realize automatic measurement of channel switching time, frequency hopping rate, frequency hopping bandwidth, frequency hopping frequency set and the like of shortwave and ultrashort wave frequency hopping stations.

Description

technical field [0001] The invention relates to the field of digital signal processing, in particular to a portable ultrashort wave frequency hopping radio performance detector. Background technique [0002] At this stage, the detection of frequency hopping radio stations mostly uses comprehensive test systems or spectrum analyzers, oscilloscopes, modulation analyzers, etc. for centralized detection. Not only the number of equipment is large but the volume is large, or the test accuracy often does not meet the ideal requirements. There is no portable frequency-hopping radio performance tester that integrates multiple functions such as spectrum analyzer, oscilloscope, and modulation analyzer. Contents of the invention [0003] The purpose of the present invention is to overcome the defects of the prior art, provide a function of integrating instruments such as oscilloscopes, spectrum analyzers, and modulation domain analyzers, which can complete the channel switching time, ...
