Abstract
patent application of the utility model discloses a radar, communication, and medical service universal receiver miniature trouble shooting meter, which consists of a wide band amplifier and the wave detector at the output terminal of the wide band amplifier. The wide band amplifier and the wave detector input terminal are provided with connecting terminals in which the output signal each extension set unit of the detected radar receiver is inducted, and the signal output terminal of the wave detector is output to an oscillometer. The technical proposal can detect and observe each extension set unit of the radar, communication, or medical service universal receiver, and has the technical characteristics of strong versatility, strong functions, small volume and convenience for operation.
Description
Technical field
The utility model relates to equipment receiver trouble hunting instruments such as radar, wireless telecommunications, medical treatment.
Background technology
To be that example describes with the radar receiver mainly below.Radar receiver is one of most important component in the radar system, and it is directly connected to the information content and the quality of common apparatus such as radar, and its technical performance and reliability thereof are most important to equipment effectivenesses such as radars.Equipment operation of receiver such as radar are in the strong electromagnetic wave environment, and its high sensitivity also makes its anti-overload ability very fragile, and are big because of its building block quantity again, operating frequency is high, adopt method of substitution to overhaul so be difficult to be equipped with sufficient accessory; Can't with attach troops to a unit in the radar system, the highest detection frequency only is the oscilloscope of tens MHz, the height that directly detects radar is put, local oscillator, frequency mixer, in the sample signal of circuit such as put; The sensitivity detector of existing receiver and noise measuring instrument can only detect the univers parameter of receiver, can not the measuring receiver height put, in put, each single-level circuit of wave detector, more can not detect local oscillator equifrequent source circuit.Take to make a receiver identical as examining-repairing instrument so have to the radar receiver composition, height is wherein put, local oscillator or frequency source, frequency mixer, in input, the output of putting with each extension unit of wave detector binding post all is set, be used for substituting a certain extension unit by the maintenance receiver.The characteristics of pointed strong, the good in anti-interference performance of this method, but can't be general to equipment such as reversed return type radars not.
Summary of the invention
Technological invention purpose of the present utility model is to provide a kind of highly versatile, can be directly shows the miniature trouble hunting instrument of radar communication medical treatment general purpose receiver of each extension unit of maintenance receiver with the radar system oscilloscope of attaching troops to a unit.The miniature trouble hunting instrument of radar communication medical treatment general purpose receiver of the present utility model technical scheme, its major technique content is: the miniature trouble hunting instrument of a kind of radar communication medical treatment general purpose receiver, it is made up of the wave detector of wide-band amplifier and wide-band amplifier output, wide-band amplifier and wave detector input are provided with the binding post of introducing each extension unit output signal of tested receiver, and the signal output part of wave detector exports oscilloscope to.
In above-mentioned overall technical architecture, its described wide-band amplifier is a wired TV amplifier.
In above-mentioned overall technical architecture, its described wave detector is the Schottky diode detector circuit.
In technique scheme, have receiver frequency source maintenance functions such as radar for making it, the self-sustained oscillation frequency source is its switching voltage prewired circuit by the multivibrator of output square-wave pulse, exports its envelope signal through wave detector.
The miniature trouble hunting instrument of radar communication medical treatment general purpose receiver of the present utility model changes continuous wave signal into pulse signal, thereby the low-frequency oscillograph that can directly utilize equipment such as radar to attach troops to a unit observes and overhauls each extension unit that comprises frequency source, thereby has highly versatile, volume is little, function is strong and easy to use technical characterstic.
