Problems solved by technology

[0002] Although the test technology of my country's airborne ultrashort wave radio stations has been developed for decades, the test method is still manually switching the instrument switch, manually reading and calculating the test data
This traditional test method has disadvantages such as low test efficiency and precision, and complicated test procedures.
When the finished product recalibration needs to get test results quickly, the production cycle is affected because the test speed is too slow

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the drawings.

[0023] The present invention provides an ultrashort wave digital radio test system, such as figure 1 Shown, including:

[0024] PC 1, power meter 4, comprehensive tester 5, probe 6, digital voltmeter 9.

[0025] The PC 1 is connected to the power meter 4, the comprehensive tester 5, and the digital voltmeter 9 respectively, and sends a control instruction signal to the comprehensive tester 5, and receives the data acquisition signals of the power meter 4, the comprehensive tester 5, and the digital voltmeter 9. Such as figure 2 As shown, the PC 1 is connected to the power meter 4, the comprehensive tester 5, and the digital voltmeter 9 through the IEEE488 interface card 2 and the IEEE488 bus 17.

[0026] The integrated tester 5 is connected to the probe 6, the radio station 10, and the PC machine 1, and executes the control command signal from the PC machine 1 during transmission, generat...

Abstract

The invention belongs to the test technique, provides an ultrashort wave digital radio test system. The system comprises a personal computer 1, a power meter 4, an integrated tester 5, a probe 6 and a digital voltmeter 9. When testing the transmitting state signals of a radio, the integrated tester 5 generates radio audio input 14; the radio modulates the radio audio input 14 into radio frequency signals; antenna signals 13 are generated through an antenna interface; the antenna signals 13 pass by the probe 6 and enter the integrated tester 5 for radio frequency signal analysis; the digital voltmeter measures the sidetone level when the radio transmits; when testing the receiving state signals of the radio, the integrated tester 5 generates radio frequency signals 12; the signals are converted into wireless signals 13 by the power meter and the probe; the wireless signals enter the radio; the radio demodulates the audio signals in the radio frequency signals; the demodulated radio audio output 16 is sent to the integrated tester 5 for analysis; and the digital voltmeter measures the amplitude. The system provided by the invention replaces the traditional manual test mode; and the test time is clearly reduced.

Description

Technical field [0001] The invention belongs to testing technology and relates to the field of computer hardware digital testing. Background technique [0002] Although the testing technology of airborne ultrashort wave radio in my country has been developed for decades, the testing method is still to manually switch the instrument on and off, and manually read and calculate the test data. This traditional test method has disadvantages such as low test efficiency and accuracy, and complicated test links. When the finished product recalibration needs to get the test results quickly, the test speed is too slow, which affects the production cycle. Summary of the invention [0003] The purpose of the present invention is to provide an ultrashort wave digital radio test system, which uses an automated digital test system to replace the traditional manual test method. [0004] The technical scheme of the present invention is: an ultrashort wave digital radio test system, including: [00...
