The R&S spectrum analyzer also uses a lot of engineers, so what should I do if there is a problem? It takes a long time to find the original factory and the efficiency is slow, and I don’t dare to disassemble the machine rashly. The following Agitek spectrum analyzer maintenance center shares the common faults and maintenance methods of the daily R&S spectrum analyzer:
The first is the visual inspection judgment method. The visual inspection and judgment method is a method to find out the fault and judge the fault range by observing the display condition of the inverter operation panel. For example, after powering on the inverter, observe whether there is any display on the operation panel and whether there is a fault code display. If there is a display, it means that the power supply and switching power supply are basically normal. part. In addition, when disassembling the inverter, you can observe whether the lines in the internal circuit board are moldy, whether the components are burnt, burnt, etc., whether the connectors are loose, whether the components are welded, etc. These are all observation methods to observe. Content.
The second is the instrument inspection method. The instrumentation inspection method is an important part of the R&S spectrum analyzer maintenance method. It is mainly a method to detect the relevant electrical parameters and component parameters on the circuit board of the faulty inverter through the instrumentation, so as to find the fault locations and faulty components. The commonly used instruments include pointer multimeters, digital multimeters, integrated circuit testers, oscilloscopes, signal generators, regulated adjustable power supplies, and so on. Through the above instruments to determine the part that caused the fault of the inverter, first compress the fault in a certain part, carefully check the electronic components in the circuit of a certain part, and finally find out the damaged electronic components and the cause of the fault. Take certain measures and methods to eliminate the cause of the inverter failure, so that the inverter can be repaired.
The above is the method and judgment of Agitek Spectrum Analyzer Service Center (www.ywkjt.com) to share about the possible problems of two common R&S spectrum analyzers. I hope it will be helpful for everyone to use this equipment in the future.
