​The structure of spectrum analyzer seems like the oscilloscope which is used for the time domain. There are many function control buttons on the board of the spectrum analyzer. As the adjustment and control of the system control, there are real time spectrum analyzer and scan tune spectrum analyzer.

​According to the different signal wave, there are four types of signal generator:1.Sinusoidal signal generator. 2.Function signal generator can generate some certain periodicity function wave form signal. 3.Pulse signal signal generator.4.Random signal generator.

​The advantages of the programmable DC power supplies is high stability, the lowest noise, low drifting liner structure. High precious programmable DC power supplier has the power measurement and compensation function.

​Spectrum analyzer is a versatile electronic measuring instruments to study on electrical signal spectrum structure, which is applied to the measurement of the signal distortion, modulation, spectral purity and frequency stability.

​The minimum output signal of the function signal generator could be less than 1mv. It is in the lead on this technology. The high-power function signal generator was the pioneer in our country. The feature of function signal generator is high stability, reliability, lower price.

​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.
