Description
Technical field
The present invention relates to the testing arrangement of short-wave radio set, especially a kind of device for quick testing of short-wave radio set combination tone.
Background technology
Combination tone is the audio frequency output that the interior each local oscillation signal of receiver and combination thereof produce, conventional short-wave radio set group at presentSynaeresis method of testing is: the equivalent aerial resistance of short wave station antenna input termination one band shielding, audio output connects audio frequencyAnalyzer manually changes short-wave radio set operating frequency with stepping Δ f in 1.6MHz～30MHz shortwave frequency range, observesAudio analyzer, write down that audio analyzer reads than the Frequency point of the low 6dB of standard signal to noise ratio, i.e. combination tone.
If frequency is calculated by stepping 1kHz, in 1.6MHz～30MHz shortwave frequency range, need manually to change 28400Frequency point, calculates by changing a Frequency point 5 seconds, and light change frequency just needs 39 hours, and test is wasted time and energy.
Summary of the invention
The technical problem solving: for the deficiencies in the prior art, the present invention proposes the quick of a kind of short-wave radio set combination toneTesting arrangement and method, solve the technical problem that prior art test combination tone is wasted time and energy.
Technical scheme: for solving the problems of the technologies described above, the present invention by the following technical solutions:
The device for quick testing of short-wave radio set combination tone and a method, comprise signal generator, audio analyzer, calculatingMachine and band shielding equivalent aerial resistance, comprise receiver in described short-wave radio set, and receiver comprises antenna input, audio frequencyOutput and serial data mouth; Signal level is inputed to antenna input by described signal generator, described audio outputThe audio frequency of output is inputed in audio analyzer and analyzes and obtain threshold value, and described band shielding equivalent aerial resistance is connected to antennaInput, described computer sends the scan frequency of stepping Δ f to serial data mouth, and receiver will by serial data mouthCurrent scan frequency and level corresponding to this frequency are sent to computer, and described computer recording exceedes the level of threshold valueCorresponding frequency is also presented on computer screen.
Apparatus of the present invention are divided into 2 steps in use, first test out threshold value, then scan, and will be instantlyLevel and threshold value that frequency is corresponding are made comparisons, once find that the level that exceeds threshold value just records its correspondence in timeFrequency, has found out combination tone.
Beneficial effect: apparatus of the present invention are simple in structure, first utilizes audio analyzer and signal generator to coordinate and obtains doorLimit value, then utilizes computer realization scanning, and judges whether in time to exceed threshold value to find out in time combination tone correspondenceFrequency. Compare traditional manual test method, the present invention can automatic scan shortwave frequency range, measures combination tone, avoidsThe action of loaded down with trivial details artificial change frequency in traditional group synaeresis test, measure accurately, save human resources, greatly shortenDetect consuming time, improved operating efficiency.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is further described.
A device for quick testing for short-wave radio set combination tone, comprises receiver 1 in described short-wave radio set, receiver 1 wrapsContaining antenna input 2, audio output 3 and serial data mouth 4, comprise signal generator 5, audio analyzer 6, meterCalculation machine 7 and band shielding equivalent aerial resistance 8; Signal level is inputed to antenna input 2 by described signal generator 5,Described audio output 3 inputs to the audio frequency of output in audio analyzer 6 and analyzes and obtain threshold value, described band shielding etc.Effect antenna resistance 8 is connected to antenna input 2, and described computer 7 sends the scanning frequency of stepping Δ f to serial data mouth 4Rate, receiver 1 is sent to computer 7 by serial data mouth 4 by current scan frequency and level corresponding to this frequency,Described computer 7 records exceed the corresponding frequency of level of threshold value and are presented on computer screen.
When use, the output level of conditioning signal generator 5, makes the short-wave radio set sound of reading on audio analyzer 6Frequently output is than the low 6dB of standard signal to noise ratio, taking signal generator 5 output signal levels now as threshold value; Then disconnect skyLine input 2 is connected with signal generator 5, accesses a band shielding equivalent aerial resistance 8, profit at antenna input 2Control short-wave radio set with computer 7 and scan with the scan frequency of stepping Δ f=1kHz in 1.6MHz～30MHz,Receiver 1 reports scan frequency and level corresponding to this frequency instantly by serial data mouth 4 to computer 7, works as meterWhen the level that calculation machine 7 is recorded to exceedes threshold value, if desired instant playback, by frequency corresponding this level at computerOn screen, show, show if do not need, continue scanning, until complete the scanning in all frequency ranges, by instituteThere is result to be presented on computer screen, finish the quick test to short-wave radio set combination tone, compare artificial frequency-selecting, utilizeThe test speed of this device greatly promotes.
The above is only the preferred embodiment of the present invention, is noted that for those skilled in the art, under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications are alsoShould be considered as protection scope of the present invention.
