​The influence of the over voltage of the output end. For example, if the voltage of the DC stabilized power supply is over 30% of the integrated circuit nominal voltage, it may cause a large number of the integrated circuit injury.

RF signal generators are essential tools for a wide range of applications, including research and development, education, and manufacturing. Professionals who require versatile and reliable signal generation often look for features such as a broad frequency range, advanced modulation capabilities, and precise signal output.

​There are two technical indicators on the DC stabilized power supply: 1.Index of characteristic, which reflect the intrinsic property of the DC stabilized power supply, such as input voltage, output voltage, current output, etc. 2.Index of quality, which reflect the good and bad of the DC stabilized power supply, such as the stability, equivale

​There are many functional control button on the spectrum analyzer panel, which are used to control and adjust the system function. The most important part which influence the signal reaction is filter bandwidth. The feature of the filter is Gaussian-Shaped Filter.

The function of the real time spectrum analyzer is to display the signal amplitude of the frequency domain in the same moment. Its working principle is there are correspondent filter and detector for different signal frequency, then transfer the signal to the CRT screen.

​The sweep-tuned spectrum analyzer is frequently-used. Its basic structure is similar with the superheterodyne receiver.
