​The tracking generator is the common implements of the spectrum analyzer. When the output of the tracking generator is connected with the input of the spectrum analyzer, the spectrum analyzer and tracking generator can form a completely sweep frequency measuring system.

​The sensitivity of the spectrum analyzer is related with the RBW. The smaller of the RBW, the better sensitivity of the spectrum analyzer. While it will slower the scan speed.

​At first, we need to reset the central frequency, span and reference level according to the tested signal. Then under the circumstance of without overload reduce the pad value gradually. If the SNR is less than 15dB, we need to reduce the RBW.

​The programmable DC power supplies device has the dangers like high voltage, large current, please do not operate unless the relevant personnel.

We all know that the spectrum analyzer can be applied in many areas and plays a important part. We need to know more about it such as how to use it properly.

The most common spectrum analyzer is the scan tune spectrum analyzer. The modulated local oscillator generate the oscillation frequency with linear variation along time with the scan generator.
