?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.

?The signal generator is a device which can provide all kinds of frequency, wave form. During the testing the amplitude characteristic, frequency characteristic, transfer characteristic and other electrical parameter of the telecommunication system or the equipment, the signal generator can be used as the signal source.

Suin’s SA9100 family of spectrum analyzers offer a frequency range of 9 KHz to 3 GHz. With their light weight, small size,and friendly user interface, the SA9100 present a bright display, powerful and reliable automatic measurements, and plenty of impressive features. Applications are widely, which include research and development, education, pro
