There are many ways to measure frequency, as we all know the comment to see is Universal Frequency Counter.According to its working principle is divided into passive frequency measurement, comparison method, oscilloscope method and counting method.

Spectrum analyzer and oscilloscopes are commonly used electronic instruments and are widely used in many industries. There is also a big difference between the spectrum analyzer and the oscilloscope.

Spectrum analyzer can be used to measure the field strength and other test.The field is very various.The usual test instruments include Universal Frequency Counter,Function Generators,etc.

China Telecom hopes to push the telecom age rapidly. The commercial 5G network under construction will be faster and smoother with more coverage. China Telecom is also willing to cooperate with China Mobile and China Unicom in the construction of network infrastructure in the future.

Electronic Instruments is a device that refers to the testing, analysis, testing of electronic products performance, quality, safety.Generally can be summarized as electronic measuring instruments

Spectrum analyzer is divided into real-time analysis and sweep type two categories. The former can get all the required spectral information in the real time of the signal under test and analyze and display the analysis results
