Radio safety guard of civil aviation airports - radio comprehensive tester
Recently, safety accidents in the field of international civil aviation have occurred frequently, which has attracted widespread attention worldwide. From aircraft landing gear failure, runway deviation to emergency landing caused by mechanical failure, these incidents not only affect the hearts of every passenger, but also once again highlight the importance of civil aviation safety. In these complex flight environments, the stability and reliability of the radio communication system are the key to ensuring flight safety. Radio comprehensive tester, as a professional detection tool for radio communication equipment, has built-in multiple test modules, which can cover a wide range of frequencies, meet the testing needs of radio equipment in different frequency bands, and escort flight safety. The following will introduce the working principle, main functions, wide application in civil aviation airports and usage of radio comprehensive tester.
Working Principle
The working principle of the radio integrated tester is based on advanced RF signal processing technology. The tester integrates multiple test instrument functions such as RF synthesis source, RF power meter, RF frequency meter, RF modulation meter, etc. When working, the tester generates RF signals of various modulation modes, such as continuous wave (CW), amplitude modulation (AM), frequency modulation (FM) and single sideband (SSB), through the RF synthesis source to stimulate the device under test. After receiving these signals, the device under test will generate corresponding response signals. The radio integrated tester uses the built-in receiving and analysis modules to measure and analyze these response signals in detail, so as to obtain various performance indicators of the device under test.
Main Functions
The radio integrated tester has multiple functions to meet the testing needs of different radio equipment in civil aviation airports:
1. RF signal generation: It can generate RF signals of various frequencies, amplitudes and modulation modes. For example, the TFN PM1200 and PM3900 radio integrated testers have built-in high-performance RF synthesis sources, and their RF signals can be used to simulate real communication environments to test the receiving and transmitting performance of radio equipment.
2. Spectrum analysis: Perform spectrum analysis on the received RF signal and measure the signal's frequency range, amplitude distribution, spectrum purity and other parameters. The TFN PM1200 and PM3900 testers are equipped with spectrum analyzers that can perform detailed spectrum analysis on the received signal and measure key parameters such as the signal's frequency, power, and bandwidth, thereby accurately evaluating the device's receiving performance.
3. Power measurement: Measure the transmit power and receiving sensitivity of the device under test. PM1200 and PM3900 have built-in RF power meters that can accurately measure the power of RF signals, including narrowband power and broadband power. This helps ensure that the device operates within the specified power range and avoids interference with other communication systems.
4. Audio signal generation and analysis: It can simulate and generate various audio signals, and measure and analyze these signals and external audio signals' parameters such as frequency and distortion through built-in analysis tools. PM1200 and PM3900 have built-in audio synthesis sources, audio voltmeters, audio frequency meters and other tools that can measure parameters such as frequency, voltage, and distortion of audio signals. This helps evaluate the audio processing capabilities of radio equipment and ensure the quality of audio communications.
5. Standing wave and cable test: It can measure the standing wave ratio, return loss and cable loss of RF transmission lines. PM1200 and PM3900 can measure the standing wave ratio of antennas and the insertion loss of transmission lines. This helps to find and solve problems with antennas and transmission lines in a timely manner and ensure the stability of communication links.
Application Scenarios
In civil aviation airports, radio integrated testers can be used in the following aspects:
1. Communication equipment testing and maintenance: used to simulate various communication signals in the airport, such as very high frequency (VHF) communication, communication between the tower and the aircraft, etc., to test the receiving and transmitting performance of these communication equipment in a real environment; used to analyze the spectrum characteristics of communication signals in the airport to ensure that the communication frequency band is not illegally occupied or interfered with, and to check the spectrum purity of the communication equipment to ensure the communication quality.
2. Power management and compliance check: measure the transmission power of each communication device in the airport to ensure that it works within the specified power range to avoid interference with other communication systems, and check the receiving sensitivity to ensure that the equipment can receive signals normally.
3. Audio communication quality assessment: used to simulate and test the voice communication system in the airport, such as the call quality between the tower and the crew. By measuring the frequency, distortion and other parameters of the audio signal, the clarity and accuracy of the audio communication are ensured.
4. Antenna and transmission line maintenance: regularly measure the standing wave ratio, return loss and cable loss of the antenna and transmission line in the airport, timely discover and solve potential problems, and ensure the stability and reliability of the communication link. This is critical to maintaining the normal operation of the airport communication system.
TFN PM1200 and PM3900 radio integrated testers feature multi-functional integration, high-precision measurement, and automated testing. Both can ensure stable performance of radio equipment. In civil aviation airports, they can be used for communication equipment testing, navigation equipment calibration, etc. to ensure flight safety and smooth communication.
