Abstract
The utility model discloses a rapid testing device of short wave radio combined sound. The rapid testing device comprises a signal generator, an audio analyzer, a computer and a tape shielding equivalent antenna resistor. A short wave radio contains a receiver which comprises an antenna input end, an audio output end and a serial data port. The signal generator inputs signal level to the antenna input end. The audio output end inputs outputted audio to the audio analyzer to obtain a threshold value. The tape shielding equivalent antenna resistor is connected to the antenna input end. The computer sends scanning frequency of stepping Delta f to the serial data port. The short wave radio sends the current scanning frequency and the level corresponding to the frequency to the computer through the serial data port. The computer records the frequency corresponding to the level which exceeds the threshold value and displays the frequency on a screen.
Description
Technical field
The present invention relates to the testing apparatus 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 combination tone method of testing is at present: the equivalent aerial resistance of short wave station antenna input termination one band shielding, audio output connects audio analyzer, in 1.6MHz～30MHz shortwave frequency range, manually change short-wave radio set operating frequency with stepping Δ f, observe audio 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 28400 Frequency points, to calculate by changing a Frequency point 5 seconds, 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 a kind of device for quick testing of short-wave radio set combination tone, solves 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:
A device for quick testing for short-wave radio set combination tone, comprises signal generator, audio analyzer, computer and band shielding equivalent aerial resistance, in described short-wave radio set, comprises receiver, and receiver comprises antenna input, audio output and serial data mouth; Signal level is inputed to antenna input by described signal generator, described audio output inputs to the audio frequency of output in audio analyzer and analyzes and obtain threshold value, described band shielding equivalent aerial resistance is connected to antenna input, described computer sends the scanning frequency of stepping Δ f to serial data mouth, receiver is sent to computer by serial data mouth by current scanning frequency and level corresponding to this frequency, and described computer recording exceedes the corresponding frequency of level of threshold value and is 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 make comparisons when corresponding level and the threshold value of lower frequency, just record in time its corresponding frequency once discovery exceeds the level of threshold value, 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 threshold value, then utilizes computer realization scanning, and judges whether in time to exceed threshold value to find out in time the frequency that combination tone is corresponding.Compare traditional manual test method, the present invention can automatic scan shortwave frequency range, measures combination tone, avoid the action of artificial change frequency loaded down with trivial details in the test of traditional group synaeresis, measured accurately, saved human resources, greatly shorten detection consuming time, improved operating efficiency.

Embodiment
Below in conjunction with accompanying drawing, the present invention is further described.
A kind of device for quick testing of short-wave radio set combination tone, in described short-wave radio set, comprise receiver 1, receiver 1 comprises antenna input 2, audio output 3 and serial data mouth 4, comprises signal generator 5, audio analyzer 6, computer 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 equivalent aerial resistance 8 is connected to antenna input 2, described computer 7 sends the scanning frequency of stepping Δ f to serial data mouth 4, receiver 1 is sent to computer 7 by serial data mouth 4 by current scanning frequency and level corresponding to this frequency, and 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, exports than the low 6dB of standard signal to noise ratio the short-wave radio set audio frequency of reading on audio analyzer 6, take signal generator 5 output signal levels now as threshold value, then disconnect being connected of antenna input 2 and signal generator 5, access a band shielding equivalent aerial resistance 8 at antenna input 2, utilize computer 7 to control short-wave radio set scans with the scanning frequency of stepping Δ f=1kHz in 1.6MHz～30MHz, receiver 1 reports scanning frequency and level corresponding to this frequency instantly by serial data mouth 4 to computer 7, when the level being recorded to when computer 7 exceedes threshold value, if desired instant playback, frequency corresponding this level is shown on computer screen, show if do not need, continue scanning, until complete the scanning in all frequency ranges, all results are presented on computer screen, finish the quick test to short-wave radio set combination tone, compare artificial frequency-selecting, utilize the test speed of this device greatly to promote.
The above is only the preferred embodiment of the present invention; be 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 also should be considered as protection scope of the present invention.
